145-634: Johann Sebastian Bach wrote two sets of partitas for different instruments. Those for solo keyboard the composer published as his Opus 1 (known as the Klavierübung I). One additional suite in B minor, the Overture in the French Style (often simply called French Overture ) is sometimes also considered a partita. See Partitas for keyboard (825–830) and choral partitas for organ. The "Partita" in A minor for solo flute (BWV 1013) which takes

290-419: A fipple , like that of a recorder , whereas reed pipes produce sound via a beating reed , like that of a clarinet or saxophone. Pipes are arranged by timbre and pitch into ranks. A rank is a set of pipes of the same timbre but multiple pitches (one for each note on the keyboard), which is mounted (usually vertically) onto a windchest . The stop mechanism admits air to each rank. For a given pipe to sound,

435-432: A 4′ Octave. When both of these stops are selected and a key (for example, c′) is pressed, two pipes of the same rank will sound: the pipe normally corresponding to the key played (c′), and the pipe one octave above that (c′′). Because the 8′ rank does not have enough pipes to sound the top octave of the keyboard at 4′ pitch, it is common for an extra octave of pipes used only for the borrowed 4′ stop to be added. In this case,

580-440: A broader range of European culture. In addition to singing in the choir, he played the school's three-manual organ and harpsichords . He also came into contact with sons of aristocrats from northern Germany who had been sent to the nearby Ritter-Academie to prepare for careers in other disciplines. In January 1703, shortly after graduating from St. Michael's and being turned down for the post of organist at Sangerhausen , Bach

725-486: A cantata, BWV 191 from his 1733 Kyrie-Gloria Mass for the Dresden court in the mid-1740s, Bach expanded that setting into his Mass in B minor in the last years of his life. The complete mass was not performed during his lifetime. It is considered among the greatest choral works in history. In January 1749, Bach's daughter Elisabeth Juliane Friederica married his pupil Johann Christoph Altnickol . Bach's health

870-402: A chamber generally called the swell box . At least one side of the box is constructed from horizontal or vertical palettes known as swell shades , which operate in a similar way to Venetian blinds ; their position can be adjusted from the console. When the swell shades are open, more sound is heard than when they are closed. Sometimes the shades are exposed, but they are often concealed behind

1015-560: A charlatan and believed to have blinded hundreds of people. Bach died on 28 July 1750 from complications due to the unsuccessful treatment. An inventory drawn up a few months after Bach's death shows that his estate included five harpsichords , two lute-harpsichords , three violins , three violas , two cellos , a viola da gamba , a lute , a spinet , and 52 "sacred books", including works by Martin Luther and Josephus . C.P.E. Bach saw to it that The Art of Fugue , though unfinished,

1160-679: A church cantata monthly in the castle church. The first three cantatas in the new series Bach composed in Weimar were Himmelskönig, sei willkommen , BWV 182 , for Palm Sunday , which coincided with the Annunciation that year; Weinen, Klagen, Sorgen, Zagen , BWV 12 , for Jubilate Sunday ; and Erschallet, ihr Lieder, erklinget, ihr Saiten!   BWV 172 for Pentecost . Bach's first Christmas cantata, Christen, ätzet diesen Tag , BWV 63 , premiered in 1714 or 1715. In 1717, Bach fell out of favour in Weimar and, according to

1305-495: A composition. He chose his Canonic Variations on "Vom Himmel hoch da komm' ich her" , and a portrait painted by Elias Gottlob Haussmann that featured Bach's Canon triplex á 6 Voc . In May 1747, Bach visited the court of King Frederick II of Prussia in Potsdam . The king played a theme for Bach and challenged him to improvise a fugue based on it. Bach obliged, playing a three-part fugue on one of Frederick's fortepianos ,

1450-457: A festive cantata for the inauguration of the new council , which was published at the council's expense. Bach left Mühlhausen in 1708, returning to Weimar this time as organist and from 1714 Konzertmeister (director of music) at the ducal court, where he could work with a large, well-funded contingent of professional musicians. Bach and his wife moved into a house near the ducal palace. Later that year, their first child, Catharina Dorothea,

1595-409: A key is depressed. The stop action causes a rank of pipes to be engaged (i.e. playable by the keys) while a stop is in its "on" position. An action may be mechanical, pneumatic, or electrical (or some combination of these, such as electro-pneumatic). The key action is independent of the stop action, allowing an organ to combine a mechanical key action with an electric stop action. A key action in which

1740-608: A large extent he defined it. Fugues are as characteristic of Bach's style as, for instance, sonata form is of the composers of the Classical period . These strictly contrapuntal compositions, and most of Bach's music in general, are characterised by distinct melodic lines for each voice, where the chords formed by the notes sounding at a given point follow the rules of four-part harmony. Johann Nikolaus Forkel , Bach's first biographer, gives this description of this feature of Bach's music, which sets it apart from most other music: If

1885-417: A large range of timbres, organ stops exist at different pitch levels. A stop that sounds at unison pitch when a key is depressed is called an 8′ (pronounced "eight-foot") pitch. This refers to the speaking length of the lowest-sounding pipe in that rank, which is approximately eight feet (2.4 m). For the same reason, a stop that sounds an octave higher is at 4′ pitch, and one that sounds two octaves higher

2030-473: A lighter touch, and more flexibility in the location of the console, within a roughly 50-foot (15-m) limit. This type of construction was used in the late 19th century and early 20th century, and has had only rare application since the 1920s. A more recent development is the electric action, which uses low voltage DC to control the key and/or stop mechanisms. Electricity may control the action indirectly by activating air pressure valves (pneumatics), in which case

2175-608: A much better and newer (1716) organ than the St. Thomas Church or the St. Nicholas Church. Bach was not required to play any organ in his official duties, but it is believed he liked to play on the St. Paul's Church organ for his own pleasure. Bach broadened his composing and performing beyond the liturgy by taking over, in March 1729, the directorship of the Collegium Musicum , a secular performance ensemble Telemann started. This

2320-501: A musician, Leopold appreciated Bach's talents, paid him well, and gave him considerable latitude in composing and performing. Leopold was a Calvinist and did not use elaborate music in his worship; accordingly, most of Bach's work from this period is secular, including the orchestral suites , cello suites , sonatas and partitas for solo violin , and the Brandenburg Concertos . Bach also composed secular cantatas for

2465-479: A new type of instrument at the time. Upon his return to Leipzig he composed a set of fugues and canons and a trio sonata based on the Thema Regium ("king's theme"). Within a few weeks this music was published as The Musical Offering and dedicated to Frederick. The Schübler Chorales , a set of six chorale preludes transcribed from cantata movements Bach had written two decades earlier, were published within

2610-427: A payment in 1332 from the clergy of Notre Dame to an organist to perform on the feasts St. Louis and St. Michael. The Notre Dame School also shows how organs could have been used within the increased use of polyphony, which would have allowed for the use of more instrumental voices within the music. According to documentation from the 9th century by Walafrid Strabo, the organ was also used for music during other parts of

2755-519: A pedalboard with thirty or thirty-two notes (two and a half octaves, from C to f′ or g′). A coupler allows the stops of one division to be played from the keyboard of another division. For example, a coupler labelled "Swell to Great" allows the stops drawn in the Swell division to be played on the Great manual. This coupler is a unison coupler, because it causes the pipes of the Swell division to sound at

2900-704: A prelude and fugue in every major and minor key, displaying a dizzying variety of structural, contrapuntal and fugal techniques. Four-part harmony predates Bach, but he lived during a time when modal music in Western tradition was largely supplanted by the tonal system . In this system a piece of music progresses from one chord to the next according to certain rules, with each chord characterised by four notes. The principles of four-part harmony are found not only in Bach's four-part choral music; he also prescribes it for instance in figured bass accompaniment. The new system

3045-699: A prolonged absence from Arnstadt: after obtaining leave for four weeks, he was absent for around four months in 1705–1706 to take lessons from the organist and composer Johann Adam Reincken and to hear him and Dieterich Buxtehude play in the northern city of Lübeck . The visit to Buxtehude and Reincken involved a 450-kilometre (280 mi) journey each way, reportedly on foot. Buxtehude probably introduced Bach to his friend Reincken so that he could learn from his compositional technique (especially his mastery of fugue ), his organ playing and his skills with improvisation. Bach knew Reincken's music very well; he copied Reincken's monumental An Wasserflüssen Babylon when he

3190-466: A row of facade-pipes or a grill. The most common method of controlling the louvers is the balanced swell pedal . This device is usually placed above the centre of the pedalboard and is configured to rotate away from the organist from a near-vertical position (in which the shades are closed) to a near-horizontal position (in which the shades are open). An organ may also have a similar-looking crescendo pedal , found alongside any expression pedals. Pressing

3335-595: A similar organ for his chapel in Aachen in 812, beginning the pipe organ's establishment in Western European church music. In England, "The first organ of which any detailed record exists was built in Winchester Cathedral in the 10th century. It was a huge machine with 400 pipes, which needed two men to play it and 70 men to blow it, and its sound could be heard throughout the city." Beginning in

3480-523: A soloist) with the orchestra in instrumental cantata movements, a decade before Handel published his first organ concertos. Apart from the 5th Brandenburg Concerto and the Triple Concerto , which already had harpsichord soloists in the 1720s, Bach wrote and arranged his harpsichord concertos in the 1730s, and in his sonatas for viola da gamba and harpsichord neither instrument plays a continuo part: they are treated as equal soloists, far beyond

3625-419: A stop labelled "Open Diapason 8′ " is a single-rank diapason stop sounding at 8′ pitch. A stop labelled "Mixture V" is a five-rank mixture. Sometimes, a single rank of pipes may be able to be controlled by several stops, allowing the rank to be played at multiple pitches or on multiple manuals. Such a rank is said to be unified or borrowed . For example, an 8′ Diapason rank may also be made available as

3770-548: A sustained period of composing keyboard and orchestral works. He attained the proficiency and confidence to extend the prevailing structures and include influences from abroad. He learned to write dramatic openings and employ the dynamic rhythms and harmonic schemes found in the music of Italians such as Vivaldi , Corelli , and Torelli . Bach absorbed these stylistic aspects to a certain extent by transcribing Vivaldi's string and wind concertos for harpsichord and organ; many of these transcribed works are still regularly performed. Bach

3915-573: A translation of the court secretary's report, was jailed for almost a month before being unfavorably dismissed: "On November 6, [1717,] the quondam [former] concertmaster and organist Bach was confined to the County Judge's place of detention for too stubbornly forcing the issue of his dismissal and finally on December 2 was freed from arrest with notice of his unfavorable discharge." Leopold, Prince of Anhalt-Köthen , hired Bach to serve as his Kapellmeister (director of music) in 1717. Himself

4060-516: A warmer, richer sound than was common in the 18th century. Organs began to be built in concert halls (such as the organ at the Palais du Trocadéro in Paris), and composers such as Camille Saint-Saëns and Gustav Mahler used the organ in their orchestral works. The development of pneumatic and electro-pneumatic key actions in the late 19th century made it possible to locate the console independently of

4205-469: A water U-tube manometer , which gives the pressure as the difference in water levels in the two legs of the manometer. The difference in water level is proportional to the difference in pressure between the wind and the atmosphere. The 0.10 psi above would register as 2.75 inches of water (70  mmAq ). An Italian organ from the Renaissance period may be on only 2.2 inches (56 mm), while (in

4350-706: A way that the divisions of the organ were visibly discernible. Twentieth-century musicologists have retroactively labelled this the Werkprinzip . In France, as in Italy, Spain and Portugal, organs were primarily designed to play alternatim verses rather than accompany congregational singing . The French Classical Organ became remarkably consistent throughout France over the course of the Baroque era, more so than any other style of organ building in history, and standardized registrations developed. This type of instrument

4495-418: A year. Around the same time, the set of five canonic variations Bach had submitted when entering Mizler's society in 1747 were also printed. Two large-scale compositions occupied a central place in Bach's last years. Beginning around 1742, he wrote and revised the various canons and fugues of The Art of Fugue , which he continued to prepare for publication until shortly before his death. After extracting

4640-559: Is Shoah for Solo Violin and Sacred Temple by Jorge Grundman , which lasts an hour and a half and was finished in 2016. Listed by composer: Johann Kuhnau : a choral partita from 'Biblische Historien'. Here it is called 'Sonata 4' (a programmatic title is added). The tune or cantus firmus is the famous chorale O Haupt voll Blut und Wunden Der todtkrancke und wieder gesunde Hiskias , 6,56MB Johann Sebastian Bach Johann Sebastian Bach (31 March [ O.S. 21 March] 1685 – 28 July 1750)

4785-461: Is a very different thing when two melodies are so interwoven that they converse together like two persons upon a footing of pleasant equality. In the first case, the accompaniment is subordinate and serves merely to support the first or principal part. In the second case, the two parts are not similarly related. New melodic combinations spring from their interweaving, out of which new forms of musical expression emerge. Suppose more parts are interwoven in

4930-438: Is at 2′ pitch. Likewise, a stop that sounds an octave lower than unison pitch is at 16′ pitch, and one that sounds two octaves lower is at 32′ pitch. Stops of different pitch levels are designed to be played simultaneously. The label on a stop knob or rocker tab indicates the stop's name and its pitch in feet. Stops that control multiple ranks display a Roman numeral indicating the number of ranks present, instead of pitch. Thus,

5075-465: Is credited with inventing the organ in the 3rd century BC. He devised an instrument called the hydraulis , which delivered a wind supply maintained through water pressure to a set of pipes. The hydraulis was played in the arenas of the Roman Empire . The pumps and water regulators of the hydraulis were replaced by an inflated leather bag in the 2nd century AD, and true bellows began to appear in

5220-595: Is harmonically more innovative than his peers', employing surprisingly dissonant chords and progressions, often extensively exploring harmonic possibilities within one piece. Bach's hundreds of sacred works are usually seen as manifesting not just his craft but also a deep faith in God. He had taught Luther's Small Catechism as the Thomaskantor in Leipzig, and some of his pieces represent it. The Lutheran chorale

5365-668: Is one of the oldest instruments still used in European classical music that has commonly been credited as having derived from Greece. Its earliest predecessors were built in ancient Greece in the 3rd century BC. The word organ is derived from the Ancient Greek ὄργανον ( órganon ), a generic term for an instrument or a tool, via the Latin organum , an instrument similar to a portative organ used in ancient Roman circus games. The Greek engineer Ctesibius of Alexandria

5510-459: Is still played. Although Bach wrote no operas, he was not averse to the genre or its ornamented vocal style. In church music, Italian composers had imitated the operatic vocal style in genres such as the Neapolitan mass . In Protestant surroundings, there was more reluctance to adopt such a style for liturgical music. Kuhnau had notoriously shunned opera and Italian virtuoso vocal music. Bach

5655-518: Is the interweaving of several melodies, which emerge now in the upper, now in the middle, and now in the lower parts. From 1720, when he was thirty-five until he died in 1750, Bach's harmony consists of this melodic interweaving of independent melodies, so perfect in their union that each part seems to constitute the true melody. Herein, Bach excels all the composers in the world. At least, I have found no one to equal him in music known to me. Even in his four-part writing, we can, not infrequently, leave out

5800-494: Is used to connect the console to the windchest, electric actions allow the console to be separated at any practical distance from the rest of the organ, and to be movable. Electric stop actions can be controlled at the console by stop knobs, by pivoted tilting tablets, or rocker tabs. These are simple switches, like wall switches for room lights. Some may include electromagnets for automatic setting or resetting when combinations are selected. Computers have made it possible to connect

5945-619: The urghun (organ) as one of the typical instruments of the Eastern Roman (Byzantine) Empire . It was often used in the Hippodrome in the imperial capital of Constantinople . A Syrian visitor describes a pipe organ powered by two servants pumping "bellows like a blacksmith's" played while guests ate at the emperor's Christmas dinner in Constantinople in 911. The first Western European pipe organ with "great leaden pipes"

6090-547: The Bach-Werke-Verzeichnis (BWV, a numbered catalogue of his works) and new critical editions of his compositions. His music was further popularised through a multitude of arrangements , including the Air on the G String and " Jesu, Joy of Man's Desiring ", and of recordings, such as three different box sets with complete performances of his oeuvre marking the 250th anniversary of his death. Johann Sebastian Bach

6235-579: The Little Organ Book , containing traditional Lutheran chorale tunes set in complex textures. In 1713, Bach was offered a post in Halle when he advised the authorities during a renovation by Christoph Cuntzius of the main organ in the west gallery of the Market Church of Our Dear Lady . In the spring of 1714, Bach was promoted to Konzertmeister , an honour that entailed performing

6380-805: The Schubler Chorales and the Toccata and Fugue in D minor ; and choral works such as the St ;Matthew Passion and the Mass in B ;minor . Since the 19th century Bach Revival , he has been generally regarded as one of the greatest composers in the history of Western music. The Bach family already counted several composers when Johann Sebastian was born as the last child of a city musician, Johann Ambrosius , in Eisenach . After being orphaned at

6525-567: The organ , and an older second cousin, Johann Ludwig Bach , was a well-known composer and violinist. Bach's mother died in 1694, and his father died eight months later. The 10-year-old Bach moved in with his eldest brother, Johann Christoph Bach , the organist at St. Michael's Church in Ohrdruf , Saxe-Gotha-Altenburg . There he studied, performed, and copied music, including his brother's, despite being forbidden to do so because scores were so valuable and private and blank ledger paper

6670-540: The Brandenburg Concertos and orchestral suites, many of Bach's newly composed or reworked pieces were performed for these venues, including parts of his Clavier-Übung ( Keyboard Practice ), his violin and keyboard concertos , and the Coffee Cantata . In 1733, Bach composed a Kyrie–Gloria Mass in B minor that he later incorporated in his Mass in B minor. He presented the manuscript to

6815-523: The Collegium Musicum gave two-hour performances, in winter at the Café Zimmermann , a coffeehouse on Catherine Street off the main market square, and in summer in the proprietor's outdoor coffee garden just outside the town walls, near the East Gate. The concerts, all free of charge, ended with Gottfried Zimmermann's death in 1741. Apart from showcasing his earlier orchestral repertoire, such as

6960-593: The Organ Reform Movement . In the late 20th century, organ builders began to incorporate digital components into their key, stop, and combination actions. Besides making these mechanisms simpler and more reliable, this also makes it possible to record and play back an organist's performance using the MIDI protocol. In addition, some organ builders have incorporated digital (electronic) stops into their pipe organs. The electronic organ developed throughout

7105-599: The Passion with Bible text reflected in recitatives, arias, choruses, and chorales, but in crafting this work, Bach created an overall experience that has been found over the intervening centuries to be both musically thrilling and spiritually profound. Bach published or carefully compiled in manuscript many collections of pieces that explored the range of artistic and technical possibilities inherent in almost every genre of his time except opera . For example, The Well-Tempered Clavier comprises two books, each of which presents

7250-583: The St Matthew and St John Passions and the Great Eighteen Chorale Preludes , their final revisions. He also programmed and adapted music by composers of a younger generation, including Pergolesi ( BWV 1083 ), and his own students, such as Goldberg ( BNB I/G/2 ). In 1746 Bach was preparing to enter Lorenz Christoph Mizler 's Society of Musical Sciences  [ de ] . To be admitted, he had to submit

7395-722: The hydraulis in Ancient Greece , in the 3rd century BC, in which the wind supply was created by the weight of displaced water in an airtight container. By the 6th or 7th century AD, bellows were used to supply Byzantine organs with wind. A pipe organ with "great leaden pipes" was sent to the West by the Byzantine emperor Constantine V as a gift to Pepin the Short , King of the Franks , in 757. Pepin's son Charlemagne requested

7540-436: The liturgical year . Bach usually led performances of his cantatas , most composed within three years of his relocation to Leipzig. He assumed the office of Thomaskantor on 30 May 1723, presenting the first new cantata, Die Elenden sollen essen , BWV 75 , in the St. Nicholas Church on the first Sunday after Trinity . Bach collected his cantatas in annual cycles. Five are mentioned in obituaries, and three are extant. Of

7685-545: The musical scale . The greater the length of the pipe, the lower its resulting pitch will be. The timbre and volume of the sound produced by a pipe depends on the volume of air delivered to the pipe and the manner in which it is constructed and voiced, the latter adjusted by the builder to produce the desired tone and volume. Hence a pipe's volume cannot be readily changed while playing. Organ pipes are divided into flue pipes and reed pipes according to their design and timbre. Flue pipes produce sound by forcing air through

7830-612: The 12th century there is evidence for permanently installed organs existing in religious settings such as the Abbey of Fécamp and other locations throughout Europe. Several innovations occurred to organs in the Middle Ages, such as the creation of the portative and the positive organ. The portative organs were small and created for secular use and made of light weight delicate materials that would have been easy for one individual to transport and play on their own. The portative organ

7975-539: The 12th century, the organ began to evolve into a complex instrument capable of producing different timbres . By the 17th century, most of the sounds available on the modern classical organ had been developed. At that time, the pipe organ was the most complex human-made device —a distinction it retained until it was displaced by the telephone exchange in the late 19th century. Pipe organs are installed in churches, synagogues, concert halls, schools, mansions, other public buildings and in private properties. They are used in

8120-596: The 13th century, the portatives represented in the miniatures of illuminated manuscripts appear to have real keyboards with balanced keys, as in the Cantigas de Santa Maria . It is difficult to directly determine when larger organs were first installed in Europe. An early detailed eyewitness account from Wulfstan of Winchester gives an idea of what organs were like prior to the 13th century, after which more records of large church organs exist. In his account, he describes

8265-477: The 18th century, Bach was primarily valued as an organist , while his keyboard music, such as The Well-Tempered Clavier , was appreciated for its didactic qualities. The 19th century saw the publication of some significant Bach biographies , and by the end of that century, all of his known music had been printed. Dissemination of scholarship on the composer continued through periodicals (and later also websites) exclusively devoted to him and other publications such as

8410-418: The 20th century. Some pipe organs were replaced by digital organs because of their lower purchase price, smaller physical size, and minimal maintenance requirements. In the early 1970s, Rodgers Instruments pioneered the hybrid organ, an electronic instrument that incorporates real pipes; other builders such as Allen Organs and Johannus Orgelbouw have since built hybrid organs. Allen Organs first introduced

8555-781: The Bach family in Leipzig, but the visit did not take place. On 7 July 1720, while Bach was away in Carlsbad with Leopold, his wife, Maria Barbara Bach , suddenly died. The next year, he met Anna Magdalena Wilcke , a young, gifted soprano 16 years his junior, who performed at the court in Köthen; they married on 3 December 1721. Together they had 13 children, six of whom survived into adulthood: Gottfried Heinrich ; Elisabeth Juliane Friederica (1726–1781); Johann Christoph Friedrich and Johann Christian , who both, especially Johann Christian, became significant musicians; Johanna Carolina (1737–1781); and Regina Susanna (1742–1809). In 1723, Bach

8700-668: The Blockwerk remained grouped together under a single stop control; these stops developed into mixtures . During the Renaissance and Baroque periods, the organ's tonal colors became more varied. Organ builders fashioned stops that imitated various instruments, such as the krummhorn and the viola da gamba . Builders such as Arp Schnitger , Jasper Johannsen, Zacharias Hildebrandt and Gottfried Silbermann constructed instruments that were in themselves artistic, displaying both exquisite craftsmanship and beautiful sound. These organs featured well-balanced mechanical key actions, giving

8845-619: The Eastern Roman Empire in the 6th or 7th century AD. Some 400 pieces of a hydraulis from the year 228 AD were revealed during the 1931 archaeological excavations in the former Roman town Aquincum , province of Pannonia (present day Budapest ), which was used as a music instrument by the Aquincum fire dormitory; a modern replica produces an enjoyable sound. The 9th century Persian geographer Ibn Khurradadhbih (d. 913), in his lexicographical discussion of instruments, cited

He later extended this work into a full mass by adding a Credo , Sanctus , and Agnus Dei , the music for which was partly based on his own cantatas and partly original. Bach's appointment as Court Composer was an element of his long-term struggle to achieve greater bargaining power with the Leipzig council. Between 1737 and 1739, Bach's former pupil Carl Gotthelf Gerlach held

9135-567: The French manner with grander reeds and mixtures, though still without pedal keyboards. The Echo division began to be enclosed in the early 18th century, and in 1712, Abraham Jordan claimed his "swelling organ" at St Magnus-the-Martyr to be a new invention. The swell box and the independent pedal division appeared in English organs beginning in the 18th century. During the Romantic period,

9280-540: The Italian Girolamo Frescobaldi . He learned theology , Latin and Greek at the local gymnasium . By 3 April 1700, Bach and his school friend Georg Erdmann—who was two years older than Bach—studied at St. Michael 's School in Lüneburg , some two weeks' travel north of Ohrdruf. Their journey was probably undertaken mostly on foot. His two years there were critical in exposing Bach to

9425-509: The Leipzig offer to negotiate better terms of employment. Bach was required to instruct the Thomasschule students in singing and provide church music for the main churches in Leipzig. He was also assigned to teach Latin but was allowed to employ four "prefects" (deputies) to do this instead. The prefects also aided with musical instruction. A cantata was required for the church services on Sundays and additional church holidays during

9570-889: The Principale were 8', the "Vigesimanona" was ½'). The highest ranks "broke back", their smallest pipes replaced by pipes pitched an octave lower to produce a kind of composite treble mixture. In England, many pipe organs were destroyed or removed from churches during the English Reformation of the 16th century and the Commonwealth period. Some were relocated to private homes. At the Restoration , organ builders such as Renatus Harris and "Father" Bernard Smith brought new organ-building ideas from continental Europe. English organs evolved from small one- or two-manual instruments into three or more divisions disposed in

9715-525: The St. Paul's Church, the church of Leipzig University . But when Bach was installed as cantor in 1723, he was put in charge only of music for festal (church holiday) services at St. Paul's Church; his petition to also provide music for regular Sunday services there (for a corresponding salary increase) went all the way to the Elector but was denied. In 1725, Bach "lost interest" in working even for festal services at St. Paul's Church and decided to appear there only on "special occasions". The St. Paul's Church had

9860-554: The Swell super octave, which adds the octave above what is played on the Swell to itself), or act as a coupler to another keyboard (for example, the Swell super-octave to Great, which adds to the Great manual the ranks of the Swell division an octave above what is played). In addition, larger organs may use unison off couplers, which prevent the stops pulled in a particular division from sounding at their normal pitch. These can be used in combination with octave couplers to create innovative aural effects, and can also be used to rearrange

10005-419: The action is electro-pneumatic . In such actions, an electromagnet attracts a small pilot valve which lets wind go to a bellows (the "pneumatic" component) which opens the pallet. When electricity operates the action directly without the assistance of pneumatics, it is commonly referred to as direct electric action . In this type, the electromagnet's armature carries a disc pallet. When electrical wiring alone

10150-532: The age of 10, he lived for five years with his eldest brother, Johann Christoph , after which he continued his musical education in Lüneburg . In 1703 he returned to Thuringia , working as a musician for Protestant churches in Arnstadt and Mühlhausen and, for longer periods, at courts in Weimar , where he expanded his organ repertory, and Köthen , where he was mostly engaged with chamber music . In 1723, he

10295-545: The canons BWV 1072–1078 are in that category, as is the bulk of the Musical Offering and the Art of Fugue . Another characteristic of Bach's style is his extensive use of counterpoint , as opposed to the homophony used in his four-part chorale settings, for example. Bach's canons, and especially his fugues, are the most characteristic of this style, which he did not invent but contributed to so fundamentally that to

10440-473: The church service—the prelude and postlude the main examples—and not just for the effect of polyphony with the choir. Other possible instances of this were short interludes played on the organ either in between parts of the church service or during choral songs, but they were not played at the same time as the choir was singing. This shows that by this point in time organs were fully used within church services and not just in secular settings. Organs from earlier in

10585-485: The console and windchests using narrow data cables instead of the much larger bundles of simple electric cables. Embedded computers in the console and near the windchests communicate with each other via various complex multiplexing syntaxes, comparable to MIDI. The wind system consists of the parts that produce, store, and deliver wind to the pipes. Pipe organ wind pressures are on the order of 0.10 psi (0.69 kPa). Organ builders traditionally measure organ wind using

10730-419: The course of a piece, is another style characteristic where Bach goes beyond the norm in his time. Baroque instruments vastly limited modulation possibilities: keyboard instruments, before a workable system of temperament , limited the keys that could be modulated to, and wind instruments, especially brass instruments such as trumpets and horns , about a century before they were fitted with valves, were tied to

10875-425: The court, such as Die Zeit, die Tag und Jahre macht , BWV 134a . Despite being born in the same year and only about 130 kilometres (80 mi) apart, Bach and Handel never met. In 1719, Bach made the 35-kilometre (22 mi) journey from Köthen to Halle with the intention to meet Handel, but Handel had left town. In 1730, Bach's oldest son, Wilhelm Friedemann, travelled to Halle to invite Handel to visit

11020-542: The courts of Köthen and Weissenfels, as well as that of the Elector Frederick Augustus (who was also King of Poland ) in Dresden . Bach frequently disagreed with his employer, Leipzig's city council, which he regarded as "penny-pinching". Johann Kuhnau had been Thomaskantor in Leipzig from 1701 until his death on 5 June 1722. Bach had visited Leipzig during Kuhnau's tenure: in 1714, he attended

11165-849: The directorship of the Collegium Musicum. In 1735, Bach started preparing his first organ music publication, which was printed as the third Clavier-Übung in 1739. From around that year he started to compile and compose the set of preludes and fugues for harpsichord that became the second book of The Well-Tempered Clavier . He received the title of "Royal Court Composer" from Augustus III in 1736. From 1740 to 1748 Bach copied, transcribed, expanded or programmed music in an older polyphonic style ( stile antico ) by, among others, Palestrina ( BNB I/P/2 ), Kerll ( BWV 241 ), Torri ( BWV Anh. 30 ), Bassani ( BWV 1081 ), Gasparini ( Missa Canonica ), and Caldara ( BWV 1082 ). Bach's style shifted in

11310-452: The drum, chimes , celesta , and harp have also been imitated in organ building. The controls available to the organist, including the keyboards , couplers , expression pedals , stops, and registration aids are accessed from the console. The console is either built into the organ case or detached from it. Keyboards played by the hands are known as manuals (from the Latin mănus , meaning "hand"). The keyboard played by

11455-497: The electronic organ in 1937 and in 1971 created the first digital organ using CMOS technology borrowed from NASA which created the digital pipe organ using sound recorded from actual speaking pipes and incorporating the sounds electronically within the memory of the digital organ thus having real pipe organ sound without the actual organ pipes. A pipe organ contains one or more sets of pipes, a wind system, and one or more keyboards. The pipes produce sound when pressurized air produced by

11600-421: The extreme) solo stops in some large 20th-century organs may require up to 50 inches (1,300 mm). In isolated, extreme cases, some stops have been voiced on 100 inches (2,500 mm). With the exception of water organs , playing the organ before the invention of motors required at least one person to operate the bellows . When signaled by the organist, a calcant would operate a set of bellows, supplying

11745-506: The feet is a pedalboard (from the Latin pēs , pĕdis , meaning "foot"). Every organ has at least one manual (most have two or more), and most have a pedalboard. Each keyboard is named for a particular division of the organ (a group of ranks) and generally controls only the stops from that division. The range of the keyboards has varied widely across time and between countries. Most current specifications call for two or more manuals with sixty-one notes (five octaves, from C to c″″) and

11890-418: The figured bass. In this way, Bach played a key role in the development of genres such as the keyboard concerto. Bach wrote virtuoso music for specific instruments as well as music independent of instrumentation. For instance, the sonatas and partitas for solo violin are considered the pinnacle of what has been written for violin, within reach of only accomplished players. The music fits the instrument, using

12035-428: The first 32' contre-bombarde was installed in the great organ of Nancy Cathedral, France. Enclosed divisions became common, and registration aids were developed to make it easier for the organist to manage the great number of stops. The desire for louder, grander organs required that the stops be voiced on a higher wind pressure than before. As a result, a greater force was required to overcome the wind pressure and depress

12180-595: The form of a suite of four dances, has been given the title "partita" by its modern editors; it is sometimes transposed for oboe . Bach also wrote three partitas for solo violin in 1720 which he paired with sonatas . (He titled each of them the German Partia , but they came to be called the Italian partita , which was introduced in the Bach Gesellschaft edition in 1879, being the more common term at

12325-609: The full expansion came with the Well-Tempered Clavier , using all keys, which Bach apparently had been developing since around 1720, the Klavierbüchlein für Wilhelm Friedemann Bach being one of its earliest examples. The second page of the Klavierbüchlein für Wilhelm Friedemann Bach is an ornament notation and performance guide that Bach wrote for his eldest son when he was nine years old. Bach

12470-484: The full gamut of its possibilities and requiring virtuosity but without bravura . Notwithstanding that the music and the instrument seem inseparable, Bach transcribed some pieces in this collection for other instruments. Similarly, the virtuoso cello suites seem tailored to the instrument, the best of what is offered for it, but Bach arranged one of the suites for lute. The same applies to much of his most virtuoso keyboard music. Bach exploited an instrument's capacities to

12615-541: The full rank of pipes (now an extended rank ) is one octave longer than the keyboard. Special unpitched stops also appear in some organs. Among these are the Zimbelstern (a wheel of rotating bells), the nightingale (a pipe submerged in a small pool of water, creating the sound of a bird warbling when wind is admitted), and the effet d'orage ("thunder effect", a device that sounds the lowest bass pipes simultaneously). Standard orchestral percussion instruments such as

12760-415: The fullest while keeping the core of the music independent of the instrument on which it is performed. In this sense, it is no surprise that Bach's music is easily and often performed on instruments it was not written for, that it is transcribed so often, and that his melodies turn up in unexpected places, such as jazz music. Apart from this, Bach left several compositions without specified instrumentation:

12905-442: The genres associated with it: more than his contemporaries (who had "moved on" to the tonal system without much exception), Bach often returned to the then-antiquated modes and genres. His Chromatic Fantasia and Fugue , emulating the chromatic fantasia genre used by earlier composers such as Dowland and Sweelinck in D dorian mode (comparable to D minor in the tonal system), is an example. Modulation , or changing key in

13050-462: The key of their tuning. Bach pushed the limits: he added "strange tones" in his organ playing, confusing the singers, according to an indictment he had to face in Arnstadt, and Louis Marchand , another early experimenter with modulation, seems to have avoided confrontation with Bach because the latter went further than anyone had done before. In the "Suscepit Israel" of his 1723 Magnificat , he had

13195-431: The keyboard compass . Most organs have many ranks of pipes of differing pitch, timbre, and volume that the player can employ singly or in combination through the use of controls called stops . A pipe organ has one or more keyboards (called manuals ) played by the hands, and a pedal clavier played by the feet; each keyboard controls its own division (group of stops). The keyboard(s), pedalboard, and stops are housed in

13340-460: The keys are connected to the windchests by only rods and levers is a mechanical or tracker action . When the organist depresses a key, the corresponding rod (called a tracker) pulls open its pallet, allowing wind to enter the pipe. In a mechanical stop action, each stop control operates a valve for a whole rank of pipes. When the organist selects a stop, the valve allows wind to reach the selected rank. The first kind of control used for this purpose

13485-434: The keys. To solve this problem, Cavaillé-Coll configured the English " Barker lever " to assist in operating the key action. This is, essentially, a servomechanism that uses wind pressure from the air plenum, to augment the force that is exerted by the player's fingers. Organ builders began to prefer specifications with fewer mixtures and high-pitched stops, more 8′ and 16′ stops and wider pipe scales. These practices created

13630-459: The language of music is merely the utterance of a melodic line, a simple sequence of musical notes, it can justly be accused of poverty. The addition of a Bass puts it upon a harmonic foundation and clarifies it but defines rather than gives it added richness. A melody so accompanied—even though all the notes are not those of the true Bass—or treated with simple embellishments in the upper parts or with simple chords used to be called "homophony". But it

13775-557: The last decade of his life, showing an increased integration of polyphonic structures and canons and other elements of the stile antico . His fourth and last Clavier-Übung volume, the Goldberg Variations for two-manual harpsichord, contained nine canons and was published in 1741. During this period, Bach also continued to adapt music of contemporaries such as Handel ( BNB I/K/2 ) and Stölzel ( BWV 200 ), and gave many of his own earlier compositions, such as

13920-405: The medieval period are evidenced by surviving keyboards and casings, but no pipes. Until the mid-15th century, organs had no stop controls. Each manual controlled ranks at many pitches, known as the "Blockwerk." Around 1450, controls were designed that allowed the ranks of the Blockwerk to be played individually. These devices were the forerunners of modern stop actions. The higher-pitched ranks of

14065-744: The more than 300 cantatas he composed in Leipzig, over 100 have been lost to posterity. Most of these works expound on the Gospel readings prescribed for every Sunday and feast day in the Lutheran year. Bach started a second annual cycle on the first Sunday after the Trinity of 1724 and composed only chorale cantatas , each based on a single church hymn. These include O Ewigkeit, du Donnerwort , BWV 20 , Wachet auf, ruft uns die Stimme , BWV 140 , Nun komm, der Heiden Heiland , BWV 62 , and Wie schön leuchtet der Morgenstern , BWV 1 . Bach drew

14210-423: The most notable and largest pipe organs in the world can be viewed at List of pipe organs . A ranking of the largest organs in the world—based on the criterion constructed by Michał Szostak , i.e. 'the number of ranks and additional equipment managed from a single console'—can be found in the quarterly magazine The Organ and in the online journal Vox Humana . The origins of the pipe organ can be traced back to

14355-462: The order of the manuals to make specific pieces easier to play. Enclosure refers to a system that allows for the control of volume without requiring the addition or subtraction of stops. In a two-manual organ with Great and Swell divisions, the Swell will be enclosed. In larger organs, parts or all of the Choir and Solo divisions may also be enclosed. The pipes of an enclosed division are placed in

14500-485: The organ as "the king of instruments", a characterization still frequently applied. The Halberstadt organ was the first instrument to use a chromatic key layout across its three manuals and pedalboard, although the keys were wider than on modern instruments. The width of the keys was slightly over two and a half inches, wide enough to be struck down by the fist, as the early keys are reported to have invariably been manipulated. It had twenty bellows operated by ten men, and

14645-569: The organ became more symphonic, capable of creating a gradual crescendo. This was made possible by voicing stops in such a way that families of tone that historically had only been used separately could now be used together, creating an entirely new way of approaching organ registration. New technologies and the work of organ builders such as Eberhard Friedrich Walcker , Aristide Cavaillé-Coll , and Henry Willis made it possible to build larger organs with more stops, more variation in sound and timbre, and more divisions. For instance, as early as in 1808,

14790-448: The organ with wind. Rather than hire a calcant, an organist might practise on some other instrument such as a clavichord or harpsichord . By the mid-19th-century bellows were also operated by water engines , steam engines or gasoline engines. Starting in the 1860s bellows were gradually replaced by rotating turbines which were later directly connected to electrical motors. This made it possible for organists to practice regularly on

14935-427: The organ's console . The organ's continuous supply of wind allows it to sustain notes for as long as the corresponding keys are pressed, unlike the piano and harpsichord whose sound begins to dissipate immediately after a key is depressed. The smallest portable pipe organs may have only one or two dozen pipes and one manual; the largest organs may have over 33,000 pipes and as many as seven manuals. A list of some of

15080-481: The organ. Most organs, both new and historic, have electric blowers , although some can still be operated manually. The wind supplied is stored in one or more regulators to maintain a constant pressure in the windchests until the action allows it to flow into the pipes. Each stop usually controls one rank of pipes, although mixtures and undulating stops (such as the Voix céleste ) control multiple ranks. The name of

15225-458: The organist at the New Church, with light duties, a relatively generous salary, and a new organ tuned in a temperament that allowed music written in a wider range of keys to be played. Despite strong family connections and a musically enthusiastic employer, tension built up between Bach and the authorities after several years in the post. Bach felt discontented by the calibre of musicians he

15370-609: The organist precise control over the pipe speech. Schnitger's organs featured particularly distinctive reed timbres and large Pedal and Rückpositiv divisions. Different national styles of organ building began to develop, often due to changing political climates. In the Netherlands, the organ became a large instrument with several divisions, doubled ranks, and mounted cornets. The organs of northern Germany also had more divisions, and independent pedal divisions became increasingly common. Organ makers began designing their cases in such

15515-403: The pallet opens, wind pressure augments tension of the pallet spring, but once the pallet opens, only the spring tension is felt at the key. This sudden decrease of key pressure against the finger provides a "breakaway" feel. A later development was the tubular-pneumatic action , which uses changes of pressure within lead tubing to operate pneumatic valves throughout the instrument. This allowed

15660-489: The performance of classical music, sacred music , secular music , and popular music . In the early 20th century, pipe organs were installed in theaters to accompany the screening of films during the silent movie era; in municipal auditoria, where orchestral transcriptions were popular; and in the homes of the wealthy. The beginning of the 21st century has seen a resurgence in installations in concert halls. A substantial organ repertoire spans over 500 years. The organ

15805-665: The pipes, greatly expanding the possibilities in organ design. Electric stop actions were also developed, which allowed sophisticated combination actions to be created. Beginning in the early 20th century in Germany and in the mid-20th century in the United States, organ builders began to build historically inspired instruments modeled on Baroque organs. They returned to building mechanical key actions, voicing with lower wind pressures and thinner pipe scales, and designing specifications with more mixture stops. This became known as

15950-459: The portative and positive organs to the installation of larger organs in major churches such as the cathedrals of Winchester and Notre Dame of Paris. In this period, organs began to be used in secular and religious settings. The introduction of organ into religious settings is ambiguous, most likely because the original position of the Church was that instrumental music was not to be allowed. By

16095-441: The same free and independent manner. In that case, the apparatus of language is correspondingly enlarged and becomes practically inexhaustible if, in addition, varieties of form and rhythm are introduced. Hence, harmony becomes no longer a mere accompaniment of melody but rather a potent agency for augmenting the richness and expressiveness of musical conversation. To serve that end, a simple accompaniment will not suffice. True harmony

16240-401: The same pitch as the keys played on the Great manual. Coupling allows stops from different divisions to be combined to create various tonal effects. It also allows every stop of the organ to be played simultaneously from one manual. Octave couplers , which add the pipes an octave above (super-octave) or below (sub-octave) each note that is played, may operate on one division only (for example,

16385-674: The service at the St. Thomas Church on the first Sunday of Advent, and in 1717 he had tested the organ of the St. Paul's Church . In 1716, Bach and Kuhnau met on the occasion of the testing and inauguration of an organ in Halle. The position was offered to Bach only after it had been offered to Georg Philipp Telemann and then to Christoph Graupner , both of whom chose to stay where they were—Telemann in Hamburg and Graupner in Darmstadt—after using

16530-477: The soprano and alto choristers from the school and the tenors and basses from the school and elsewhere in Leipzig. Performing at weddings and funerals provided extra income for these groups; probably for this purpose, and for in-school training, he wrote at least six motets . As part of his regular church work, he performed other composers' motets, which served as formal models for his own. Bach's predecessor as cantor, Johann Kuhnau, had also been music director for

16675-599: The sound of the organ: "among them bells outstanding in tone and size, and an organ [sounding] through bronze pipes prepared according to the musical proportions." This is one of the earliest accounts of organs in Europe and also indicates that the organ was large and more permanent than other evidence would suggest. The first organ documented to have been permanently installed was one installed in 1361 in Halberstadt , Germany. The first documented permanent organ installation likely prompted Guillaume de Machaut to describe

16820-448: The stop governing the pipe's rank must be engaged, and the key corresponding to its pitch must be depressed. Ranks of pipes are organized into groups called divisions. Each division generally is played from its own keyboard and conceptually comprises an individual instrument within the organ. An organ contains two actions, or systems of moving parts: the keys, and the stops. The key action causes wind to be admitted into an organ pipe while

16965-748: The stop reflects not only the stop's timbre and construction, but also the style of the organ in which it resides. For example, the names on an organ built in the north German Baroque style generally will be derived from the German language, while the names of similar stops on an organ in the French Romantic style will usually be French. Most countries tend to use only their own languages for stop nomenclature. English-speaking nations as well as Japan are more receptive to foreign nomenclature. Stop names are not standardized: two otherwise identical stops from different organs may have different names. To facilitate

17110-540: The time.) See: Sonatas and partitas for solo violin . The most prolific composer of partitas for harpsichord was Christoph Graupner , whose works in the form number about 57. The first set was published in 1718 and dedicated to his patron Ernest Louis, Landgrave of Hesse-Darmstadt . The last of his partitas exist in manuscripts dated 1750. They are difficult and virtuosic pieces which exhibit an astonishing variety of musical styles. See: List of harpsichord pieces by Christoph Graupner . The longest partita ever written so far

17255-1014: The title of court composer in 1736. In the last decades of his life, Bach reworked and extended many of his earlier compositions. He died of complications after a botched eye surgery in 1750 at the age of 65. Bach enriched established German styles through his mastery of counterpoint , harmonic and motivic organisation, and his adaptation of rhythms, forms, and textures from abroad, particularly Italy and France. His compositions include hundreds of cantatas , both sacred and secular . He composed Latin church music , Passions , oratorios , and motets . He often adopted Lutheran hymns , not only in his larger vocal works but, for instance, also in his four-part chorales and his sacred songs . Bach wrote extensively for organ and for other keyboard instruments . He composed concertos , for instance for violin and for harpsichord , and suites , as chamber music as well as for orchestra . Many of his works employ contrapuntal techniques like canon and fugue . In

17400-513: The trumpets in E-flat play a melody in the enharmonic scale of C minor. The major development in Bach's time to which he contributed in no small way was a temperament for keyboard instruments that allowed their use in every key (12 major and 12 minor) and also modulation without retuning. His Capriccio on the departure of a beloved brother , a very early work, showed a gusto for modulation unlike any contemporary work it has been compared to, but

17545-431: The upper and lower parts and still find the middle parts harmonious and agreeable. Pipe organ The pipe organ is a musical instrument that produces sound by driving pressurised air (called wind ) through the organ pipes selected from a keyboard . Because each pipe produces a single pitch, the pipes are provided in sets called ranks , each of which has a common timbre , volume, and construction throughout

17690-399: The wind pressure was so high that the player had to use the full strength of their arm to hold down a key. Records of other organs permanently installed and used in worship services in the late 13th and 14th centuries are found in large cathedrals such as Notre Dame , the latter documenting organists hired to by the church and the installation of larger and permanent organs. The earliest is

17835-455: The wind system passes through them. An action connects the keyboards to the pipes. Stops allow the organist to control which ranks of pipes sound at a given time. The organist operates the stops and the keyboards from the console . Organ pipes are made from either wood or metal and produce sound ("speak") when air under pressure ("wind") is directed through them. As one pipe produces a single pitch , multiple pipes are necessary to accommodate

17980-704: Was 15 years old. Bach later wrote several other works on the same theme. When Bach revisited Reincken in 1720 and showed him his improvisatory skills on the organ, Reincken reportedly remarked: "I thought that this art was dead, but I see that it lives in you." In 1706, Bach applied for a post as organist at the Blasius Church in Mühlhausen . As part of his application, he had a cantata performed on Easter, 24 April 1707, likely an early version of his Christ lag in Todes Banden . Bach's application

18125-400: Was a "flue-piped keyboard instrument, played with one hand while the other operated the bellows." Its portability made the portative useful for the accompaniment of both sacred and secular music in a variety of settings. The positive organ was larger than the portative organ but was still small enough to be portable and used in a variety of settings like the portative organ. Toward the middle of

18270-410: Was a German composer and musician of the late Baroque period . He is known for his prolific output across a variety of instruments and forms, including orchestral music such as the Brandenburg Concertos ; solo instrumental works such as the cello suites and sonatas and partitas for solo violin ; keyboard works such as the Goldberg Variations and The Well-Tempered Clavier ; organ works such as

18415-433: Was a draw stop knob , which the organist selects by pulling (or drawing) toward himself/herself. Pulling all of the knobs thus activates all available pipes, and is the origin of the idiom " to pull out all the stops ". More modern stop selectors, utilized in electric actions, are ordinary electrical switches and/or magnetic valves operated by a rocker tab. Tracker action has been used from antiquity to modern times. Before

18560-598: Was accepted a month later, and he took up the post in July. The position included significantly higher remuneration, improved conditions, and a better choir. Four months after arriving at Mühlhausen, Bach married Maria Barbara Bach , his second cousin. Bach convinced the church and town government at Mühlhausen to fund an expensive renovation of the organ at the Blasius Church. In 1708, Bach wrote Gott ist mein König ,

18705-690: Was appointed Thomaskantor director of church music in Leipzig. He had to direct the St. Thomas School and provide four churches with music, the St. Thomas Church , the St. Nicholas Church , and to a lesser extent, the New Church and St. Peter's Church . This was "the leading cantorate in Protestant Germany", located in the mercantile city in the Electorate of Saxony , which he held for 27 years, until his death. During that time he gained further prestige through honorary appointments at

18850-471: Was appointed court musician in the chapel of Duke Johann Ernst III in Weimar . His role there is unclear, but it probably included menial, non-musical duties. During his seven-month tenure at Weimar, his reputation as a keyboardist spread so widely that he was invited to inspect the new organ and give the inaugural recital at the New Church (now Bach Church ) in Arnstadt , about 30 kilometres (19 mi) southwest of Weimar. On 14 August 1703, he became

18995-404: Was at the core of Bach's style, and his compositions are to a large extent considered to have laid down the rules for the evolving scheme that dominated musical expression in the next centuries. Some examples of this characteristic of Bach's style and its influence: Bach's insistence on the tonal system and contribution to shaping it did not imply he was less at ease with the older modal system and

19140-512: Was born in Eisenach , the capital of the duchy of Saxe-Eisenach , in present-day Germany, on 21 March 1685 O.S. (31 March 1685 N.S. ). He was the eighth and youngest child of Johann Ambrosius Bach , the director of the town musicians, and Maria Elisabeth Lämmerhirt . His father likely taught him violin and basic music theory . His uncles were all professional musicians who worked as church organists, court chamber musicians, and composers. One uncle, Johann Christoph Bach , introduced him to

19285-495: Was born, and Maria Barbara's elder, unmarried sister joined them. She remained to help run the household until she died in 1729. Three sons were also born in Weimar: Wilhelm Friedemann , Carl Philipp Emanuel , and Johann Gottfried Bernhard . Johann Sebastian and Maria Barbara had three more children—twins born in 1713 and a single birth; none survived past their first birthday. Bach's time in Weimar began

19430-420: Was collaborating with. He called one of them, Geyersbach, a "Zippel Fagottist" ( weenie bassoonist ). Late one evening, Geyersbach went after Bach with a stick. Bach filed a complaint against Geyersbach with the authorities. They acquitted Geyersbach with a minor reprimand and ordered Bach to be more moderate about the musical qualities he expected from his students. Some months later, Bach upset his employer with

19575-474: Was costly. He received valuable teaching from his brother, who instructed him on the clavichord . Johann Christoph exposed him to the works of great composers of the day, including South Germans such as Johann Caspar Kerll , Johann Jakob Froberger , and Johann Pachelbel (under whom Johann Christoph had studied); North Germans; Frenchmen such as Jean-Baptiste Lully , Louis Marchand , and Marin Marais ; and

19720-506: Was declining. On 2 June, Heinrich von Brühl wrote to one of the Leipzig burgomasters to request that his music director, Gottlob Harrer , fill the Thomaskantor and Director musices posts "upon the eventual ... decease of Mr. Bach". Becoming blind, Bach underwent eye surgery in March 1750 and again in April by the British eye surgeon John Taylor , a man widely understood today as

19865-423: Was elaborately described by Dom Bédos de Celles in his treatise L'art du facteur d'orgues ( The Art of Organ Building ). The Italian Baroque organ was often a single-manual instrument, without pedals. It was built on a full diapason chorus of octaves and fifths. The stop-names indicated the pitch relative to the fundamental ("Principale") and typically reached extremely short nominal pipe-lengths (for example, if

20010-576: Was generally quite specific on ornamentation in his compositions (in his time, much ornamentation was not written out by composers but rather considered a liberty of the performer), and his ornamentation was often quite elaborate. For instance, the "Aria" of the Goldberg Variations has rich ornamentation in nearly every measure. Bach's approach to ornamentation can also be seen in a keyboard arrangement he made of Marcello 's Oboe Concerto : he added explicit ornamentation, which centuries later

20155-532: Was hired as Thomaskantor ( cantor at St Thomas's ) in Leipzig . There, he composed music for the principal Lutheran churches of the city and its university's student ensemble Collegium Musicum . In 1726, he began publishing his keyboard and organ music. In Leipzig, as had happened during some of his earlier positions, he had difficult relations with his employer. This situation was somewhat remedied when his sovereign, Augustus III of Poland , granted him

20300-409: Was less moved. After a performance of his St Matthew Passion , someone said it all sounded much like opera. In concerted playing in Bach's time, the basso continuo, consisting of instruments such as organ, viola da gamba , or harpsichord, usually had the role of accompaniment, providing a piece's harmonic and rhythmic foundation. Beginning in the 1720s, Bach had the organ play concertante (i.e., as
