Electromechanics combines processes and procedures drawn from electrical engineering and mechanical engineering . Electromechanics focuses on the interaction of electrical and mechanical systems as a whole and how the two systems interact with each other. This process is especially prominent in systems such as those of DC or AC rotating electrical machines which can be designed and operated to generate power from a mechanical process ( generator ) or used to power a mechanical effect ( motor ). Electrical engineering in this context also encompasses electronics engineering .
135-496: The Mellotron is an electro-mechanical musical instrument developed in Birmingham , England, in 1963. It is played by pressing its keys, each of which causes a length of magnetic tape to contact a capstan , which pulls it across a playback head . As the key is released, the tape is retracted by a spring to its initial position. Different portions of the tape can be played to access different sounds. The Mellotron evolved from
270-426: A cellist or violoncellist , it enjoys a large solo repertoire with and without accompaniment , as well as numerous concerti . As a solo instrument, the cello uses its whole range, from baritone to soprano, and in chamber music, such as string quartets and the orchestra 's string section , it often plays the bass part, where it may be reinforced an octave lower by the double basses . Figured bass music of
405-476: A Moroccan -sounding horn section, " She's a Rainbow ", " 2000 Light Years from Home " and " Jigsaw Puzzle ". The Mellotron became a key instrument in progressive rock . King Crimson bought two Mellotrons when forming in 1969. They were aware of Pinder's contributions to the Moody Blues and did not want to sound similar, but concluded there was no other way of generating the orchestral sound. The instrument

The French electronic duo Air extensively used a M400 on their two first albums Moon Safari in 1998 and The Virgin Suicides in 1999. Spock's Beard 's Ryo Okumoto is a fan of the Mellotron, saying it characterises the sound of the band. Porcupine Tree 's Steven Wilson has acquired one of King Crimson's old Mellotrons and, in 2013, gave
2430-575: A performance scholarship for cello, played a prominent cello part in "As You Said" on Cream 's Wheels of Fire studio album (1968). In the 1970s, the Electric Light Orchestra enjoyed great commercial success taking inspiration from so-called "Beatlesque" arrangements, adding the cello (and violin) to the standard rock combo line-up and in 1978 the UK-based rock band Colosseum II collaborated with cellist Julian Lloyd Webber on
2565-423: A popular misconception, the cello did not evolve from the viola da gamba, but existed alongside it for about two and a half centuries. The violin family is also known as the viola da braccio (meaning viola for the arm) family, a reference to the primary way the members of the family are held. This is to distinguish it from the viola da gamba (meaning viola for the leg) family, in which all the members are all held with
2700-611: A potential customer, the BBC became interested in the possibilities of the instrument, hoping it would allow them to increase throughput at the Radiophonic Workshop . Two custom-made models loaded with sound effects were acquired in 1963, but the Radiophonic Workshop were unenthusiastic and problems with fluctuating tape speed and noise meant the sound was not up to professional broadcast quality. They ended up in

Pinder says he introduced John Lennon and Paul McCartney to the Mellotron, and convinced each of them to buy one. The Beatles hired a machine and used it on their single " Strawberry Fields Forever ", recorded in various takes between November and December 1966. Author Mark Cunningham describes
3375-409: A solid wooden cylinder which is wedged between the top and bottom plates. The bass bar, found under the bass foot of the bridge, serves to support the cello's top and distribute the vibrations from the strings to the body of the instrument. The soundpost, found under the treble side of the bridge, connects the back and front of the cello. Like the bridge, the soundpost is not glued but is kept in place by
3510-629: A solo cellist accompanied by an entire orchestra. There are numerous cello concertos – where a solo cello is accompanied by an orchestra – notably 25 by Vivaldi , 12 by Boccherini, at least three by Haydn , three by C. P. E. Bach, two by Saint-Saëns , two by Dvořák, and one each by Robert Schumann, Lalo , and Elgar. There were also some composers who, while not otherwise cellists, did write cello-specific repertoire, such as Nikolaus Kraft , who wrote six cello concertos. Beethoven 's Triple Concerto for Cello, Violin and Piano and Brahms ' Double Concerto for Cello and Violin are also part of

The cello's light sound was not as suitable for church and ensemble playing, so it had to be doubled by organ , theorbo , or violone . Around 1700, Italian players popularized the cello in northern Europe, although
4050-504: A time when a typical house cost £2,000–£3,000. Fransen failed to explain to the Bradleys that he was not the owner of the concept, and Chamberlin was unhappy with the fact that someone overseas was copying his idea. After some acrimony between the two parties, a deal was struck between them in 1966, whereby they would both continue to manufacture instruments independently. Bradmatic renamed themselves Streetly Electronics in 1970. In 1970,
4185-463: A typical guitar, the performer would only be able to bow the leftmost and rightmost two strings or bow all the strings. The performer would not be able to play the inner two strings alone. The nut is a raised piece of wood, fitted where the fingerboard meets the pegbox, in which the strings rest in shallow slots or grooves to keep them the correct distance apart. The pegbox houses four tapered tuning pegs , one for each string. The pegs are used to tune

Similarly, there is a choice of six lead stations, each containing three lead instruments which can be mixed. In the centre of the Mellotron, there is a tuning button that allows a variation in pitch (tempo, in the case of the rhythm tracks). Later models do not have
4995-492: Is a member of the traditional string quartet as well as string quintets , sextet or trios and other mixed ensembles. There are also pieces written for two, three, four, or more cellos; this type of ensemble is also called a "cello choir" and its sound is familiar from the introduction to Rossini 's William Tell Overture as well as Zaccharia's prayer scene in Verdi 's Nabucco . Tchaikovsky 's 1812 Overture also starts with
5130-427: Is a middle pitched bowed (sometimes plucked and occasionally hit ) string instrument of the violin family . Its four strings are usually tuned in perfect fifths : from low to high, C 2 , G 2 , D 3 and A 3 . The viola 's four strings are each an octave higher. Music for the cello is generally written in the bass clef , tenor clef, alto clef and treble clef used for higher-range passages. Played by
5265-879: Is becoming well known for playing the cello like a guitar, with her cover of The Beatles ' " Blackbird ". The cello is typically made from carved wood, although other materials such as carbon fiber or aluminum may be used. A traditional cello has a spruce top, with maple for the back, sides, and neck. Other woods, such as poplar or willow , are sometimes used for the back and sides. Less expensive cellos frequently have tops and backs made of laminated wood . Laminated cellos are widely used in elementary and secondary school orchestras and youth orchestras , because they are much more durable than carved wood cellos (i.e., they are less likely to crack if bumped or dropped) and they are much less expensive. The top and back are traditionally hand-carved, though less expensive cellos are often machine-produced. The sides, or ribs, are made by heating
5400-411: Is derived from the root viola , which was derived from Medieval Latin vitula , meaning stringed instrument. Cellos are tuned in fifths , starting with C 2 (two octaves below middle C ), followed by G 2 , D 3 , and then A 3 . It is tuned in the exact same intervals and strings as the viola , but an octave lower. Similar to the double bass , the cello has an endpin that rests on
5535-451: Is located on stage left (the audience's right) in the front, opposite the first violin section. However, some orchestras and conductors prefer switching the positioning of the viola and cello sections. The principal cellist is the section leader, determining bowings for the section in conjunction with other string principals, playing solos, and leading entrances (when the section begins to play its part). Principal players always sit closest to

5670-520: Is much harder and more expensive. Ebonized parts such as tuning pegs may crack or split, and the black surface of the fingerboard will eventually wear down to reveal the lighter wood underneath. Historically, cello strings had cores made out of catgut , which, despite its name, is made from sheep or goat intestines. Most modern strings used in the 2010s are wound with metallic materials like aluminum , titanium and chromium . Cellists may mix different types of strings on their instruments. The pitches of
5805-401: Is not glued but rather held in place by the tension of the strings. The bridge is usually positioned by the cross point of the "f-hole" (i.e., where the horizontal line occurs in the "f"). The f-holes , named for their shape, are located on either side of the bridge and allow air to move in and out of the instrument as part of the sound-production process. The f-holes also act as access points to
5940-462: Is played. Pressing a key harder allows the head to come into contact under greater pressure, to the extent that the Mellotron responds to aftertouch . Another factor in the Mellotron's sound is that the individual notes were recorded in isolation. For a musician accustomed to playing in an orchestral setting, this was unusual, and meant that they had nothing against which to intonate. Noted cellist Reginald Kilbey refused to downtune his cello to cover
6075-458: Is pulled out to lengthen it. The endpin is locked into the player's preferred length with a screw mechanism. The adjustable nature of endpins enables performers of different ages and body sizes to adjust the endpin length to suit them. In the Baroque period, the cello was held between the calves, as there was no endpin at that time. The endpin was "introduced by Adrien Servais c. 1845 to give
6210-422: Is the second largest stringed instrument (the double bass is the largest). Thus, the name "violoncello" contained both the augmentative " -one " ("big") and the diminutive " -cello " ("little"). By the turn of the 20th century, it had become common to shorten the name to 'cello, with the apostrophe indicating the missing stem. It is now customary to use "cello" without apostrophe as the full designation. Viol
6345-626: Is to bring the instrument in for a particular song. In the 1960s, artists such as the Beatles and Cher used the cello in popular music, in songs such as The Beatles' " Yesterday ", " Eleanor Rigby " and " Strawberry Fields Forever ", and Cher's " Bang Bang (My Baby Shot Me Down) ". " Good Vibrations " by the Beach Boys includes the cello in its instrumental ensemble, which includes a number of instruments unusual for this sort of music. Bass guitarist Jack Bruce , who had originally studied music on
6480-563: The American Music Awards . The instrument has also been modified for Indian classical music by Nancy Lesh and Saskia Rao-de Haas . The violin family , including cello-sized instruments, emerged c. 1500 as a family of instruments distinct from the viola da gamba family. The earliest depictions of the violin family, from Italy c. 1530 , show three sizes of instruments, roughly corresponding to what we now call violins , violas , and cellos. Contrary to
6615-537: The Baroque era typically assumes a cello, viola da gamba or bassoon as part of the basso continuo group alongside chordal instruments such as organ , harpsichord , lute , or theorbo . Cellos are found in many other ensembles, from modern Chinese orchestras to cello rock bands. The name cello is derived from the ending of the Italian violoncello , which means "little violone ". Violone ("big viola")
6750-713: The Berlin Philharmonic Orchestra (or "the Twelve" as they have since taken to being called) specialize in this repertoire and have commissioned many works, including arrangements of well-known popular songs. The cello is less common in popular music than in classical music. Several bands feature a cello in their standard line-up, including Hoppy Jones of the Ink Spots and Joe Kwon of the Avett Brothers . The more common use in pop and rock
6885-577: The Sparrow Quartet and the "Cajun cellist" Sean Grissom, as well as Vyvienne Long , who, in addition to her own projects, has played for those of Damien Rice . Cellists such as Natalie Haas , Abby Newton, and Liz Davis Maxfield have contributed significantly to the use of cello playing in Celtic folk music, often with the cello featured as a primary melodic instrument and employing the skills and techniques of traditional fiddle playing.

This equipment became cheaper because it used more reliably integrated microcontroller circuits containing ultimately a few million transistors, and a program to carry out the same task through logic. With electromechanical components there were only moving parts, such as mechanical electric actuators . This more reliable logic has replaced most electromechanical devices, because any point in
7695-404: The 20th century, the cello repertoire grew immensely. This was partly due to the influence of virtuoso cellist Mstislav Rostropovich, who inspired, commissioned, and premiered dozens of new works.

Other notable examples include Hindemith 's and Ysaÿe 's Sonatas for Solo Cello, Dutilleux's Trois Strophes sur le Nom de Sacher , Berio's Les Mots Sont Allés , Cassadó 's Suite for Solo Cello, Ligeti's Solo Sonata , Carter's two Figment s and Xenakis ' Nomos Alpha and Kottos . There are also modern solo pieces written for cello, such as Julie-O by Mark Summer . The cello
9585-445: The bestselling M400, dispensed with the accompaniments and some sound selection controls so it could be used by touring musicians. The instrument's popularity declined in the 1980s after the introduction of polyphonic synthesizers and samplers , despite high-profile performers such as Orchestral Manoeuvres in the Dark and XTC continuing to use the instrument. Production of the Mellotron ceased in 1986, but it regained popularity in
9720-617: The bow under the hand) back and increase the tension of the hair. Rosin is applied by the player to make the hair sticky. Bows need to be re-haired periodically. Baroque -style (1600–1750) cello bows were much thicker and were formed with a larger outward arch than modern cello bows. The inward arch of a modern cello bow produces greater tension, which in turn produces a louder sound. The cello bow has also been used to play electric guitars . Jimmy Page pioneered its application on tracks such as " Dazed and Confused ". The post-rock Icelandic band Sigur Rós 's lead singer often plays guitar using
9855-407: The calves of the player. Modern bows curve in and are held at the frog ; Baroque bows curve out and are held closer to the bow's point of balance. Modern strings are normally flatwound with a metal (or synthetic) core; Baroque strings are made of gut , with the G and C strings wire-wound. Modern cellos often have fine tuners connecting the strings to the tailpiece, which makes it much easier to tune
9990-678: The cello are Johann Sebastian Bach 's six unaccompanied Suites . Other significant works include Sonatas and Concertos by Antonio Vivaldi , and solo sonatas by Francesco Geminiani and Giovanni Bononcini . Domenico Gabrielli was one of the first composers to treat the cello as a solo instrument. As a basso continuo instrument the cello may have been used in works by Francesca Caccini (1587–1641), Barbara Strozzi (1619–1677) with pieces such as Il primo libro di madrigali, per 2–5 voci e basso continuo, op. 1 and Elisabeth Jacquet de La Guerre (1665–1729), who wrote six sonatas for violin and basso continuo. Francesco Supriani 's Principij da imparare
10125-719: The cello as a solo instrument; both tuned their instruments in fourths, an octave above the double bass. Fred Katz (who was not a bassist) was one of the first notable jazz cellists to use the instrument's standard tuning and arco technique. Contemporary jazz cellists include Abdul Wadud , Diedre Murray , Ron Carter , Dave Holland , David Darling , Lucio Amanti , Akua Dixon , Ernst Reijseger , Fred Lonberg-Holm , Tom Cora and Erik Friedlander . Modern musical theatre pieces like Jason Robert Brown's The Last Five Years , Duncan Sheik's Spring Awakening , Adam Guettel's Floyd Collins , and Ricky Ian Gordon's My Life with Albertine use small string ensembles (including solo cellos) to
10260-534: The cello by either tightening or loosening the string. The pegs are called "friction pegs", because they maintain their position by friction. The scroll is a traditional ornamental part of the cello and a feature of all other members of the violin family . Ebony is usually used for the tuning pegs, fingerboard, and nut, but other hardwoods, such as boxwood or rosewood , can be used. Black fittings on low-cost instruments are often made from inexpensive wood that has been blackened or "ebonized" to look like ebony , which
10395-480: The cello existed before the 18th century and those that do exist contain little value to the performer beyond simple accounts of instrumental technique. One of the earliest cello manuals is Michel Corrette 's Méthode, thèorique et pratique pour apprendre en peu de temps le violoncelle dans sa perfection (Paris, 1741). Cellos are part of the standard symphony orchestra , which usually includes eight to twelve cellists. The cello section, in standard orchestral seating,
10530-419: The cello from slipping on the floor. Many cellists use a rubber pad with a metal cup to keep the tip from slipping on the floor. A number of accessories exist to keep the endpin from slipping; these include ropes that attach to the chair leg and other devices. The bridge holds the strings above the cello and transfers their vibrations to the top of the instrument and the soundpost inside (see below). The bridge
10665-436: The concept of stations and have a single knob to select a sound, along with the tuning control. However, the frame containing the tapes is designed to be removed, and replaced with one with different sounds. Although the Mellotron was designed to reproduce the sound of the original instrument, replaying a tape creates minor fluctuations in pitch ( wow and flutter ) and amplitude, so a note sounds slightly different each time it
10800-416: The concertante repertoire, although in both cases the cello shares solo duties with at least one other instrument. Moreover, several composers wrote large-scale pieces for cello and orchestra, which are concertos in all but name. Some familiar "concertos" are Richard Strauss ' tone poem Don Quixote , Tchaikovsky 's Variations on a Rococo Theme , Bloch 's Schelomo and Bruch 's Kol Nidrei . In
10935-404: The early 21st century, there has been research on nanoelectromechanical systems (NEMS). Today, electromechanical processes are mainly used by power companies. All fuel based generators convert mechanical movement to electrical power. Some renewable energies such as wind and hydroelectric are powered by mechanical systems that also convert movement to electricity. In the last thirty years of
11070-597: The first Camille Saint-Saëns Concerto , as well as the two sonatas and the Double Concerto by Johannes Brahms . A review of compositions for cello in the Romantic era must include the German composer Fanny Mendelssohn (1805–1847), who wrote Fantasia in G Minor for cello and piano and a Capriccio in A-flat for cello. Compositions from the late 19th and early 20th century include three cello sonatas (including
11205-527: The first planar transistors, the first in which drain and source were adjacent at the same surface. MOSFET scaling , the miniaturisation of MOSFETs on IC chips, led to the miniaturisation of electronics (as predicted by Moore's law and Dennard scaling ). This laid the foundations for the miniaturisation of mechanical systems, with the development of micromachining technology based on silicon semiconductor devices , as engineers began realizing that silicon chips and MOSFETs could interact and communicate with
11340-519: The first pop songs featuring the Mellotron was Manfred Mann 's " Semi-Detached, Suburban Mr. James " (1966). The Beatles used it on tracks including the hit single " Strawberry Fields Forever " (1967). The Moody Blues keyboardist Mike Pinder used it extensively on the band's 1967 album Days of Future Passed as well as the group's following six albums. During the 1970s, the Mellotron became common in progressive rock , used by groups such as King Crimson , Yes and Genesis . Later models, such as
11475-406: The floor to support the instrument's weight. The cello is most closely associated with European classical music . The instrument is a part of the standard orchestra , as part of the string section , and is the bass voice of the string quartet (although many composers give it a melodic role as well), as well as being part of many other chamber groups. Among the most well-known Baroque works for
11610-592: The home and the characteristics of the instrument attracted a number of celebrities. Among the early Mellotron owners were Princess Margaret , Peter Sellers , King Hussein of Jordan and Scientology founder L. Ron Hubbard (whose Mellotron was installed in the Church of Scientology's head UK office at Saint Hill Manor ). According to Robin Douglas-Home , Princess Margaret "adored it; ( Lord Snowdon ) positively loathed it". After Mellotronics had targeted them as
11745-460: The home or in clubs and were not designed for touring bands. Even the later M400, which was designed to be as portable as possible, weighed over 122 pounds (55 kg). Smoke, variations in temperature, and humidity were also detrimental to the instrument's reliability. Moving the instrument between cold storage rooms and brightly lit stages could cause the tapes to stretch and stick on the capstan. Leslie Bradley recalls receiving some Mellotrons in for
11880-421: The important three periods of his compositional evolution. Other outstanding examples include the three Concerti by Carl Philipp Emanuel Bach , Capricci by dall'Abaco, and Sonatas by Flackton, Boismortier, and Luigi Boccherini . A Divertimento for Piano, Clarinet, Viola and Cello is among the surviving works by Duchess Anna Amalia of Brunswick-Wolfenbüttel (1739–1807). Wolfgang Amadeus Mozart supposedly wrote
12015-428: The indie rock band Canada employs two cello players in their lineup. The orch-rock group The Polyphonic Spree , which has pioneered the use of stringed and symphonic instruments, employs the cello in creative ways for many of their " psychedelic -esque" melodies. The first-wave screamo band I Would Set Myself On Fire For You featured a cello as well as a viola to create a more folk -oriented sound. The band Panic! at
12150-411: The instrument greater stability". Modern endpins are retractable and adjustable; older ones were removed when not in use. (The word "endpin" sometimes also refers to the button of wood located at this place in all instruments in the violin family, but this is usually called "tailpin". ) The sharp tip of the cello's endpin is sometimes capped with a rubber tip that protects the tip from dulling and prevents
12285-484: The instrument in a different way to a typical orchestra, using block chords, and later stated that he used it in the same manner as a synth pad on later albums. His unaccompanied introduction to " Watcher of the Skies " on the album Foxtrot (1972), played on a Mk II with combined strings and brass, became significant enough that Streetly Electronics provided a "Watcher Mix" sound with the M4000. Banks claims to still have
12420-408: The instrument, but such pins are rendered ineffective by the flexibility of the gut strings used on Baroque cellos. Overall, the modern instrument has much higher string tension than the Baroque cello, resulting in a louder, more projecting tone, with fewer overtones. In addition, the instrument was less standardized in size and number of strings; a smaller, five-string variant (the violoncello piccolo)
12555-426: The interior of the cello for repairs or maintenance. Sometimes a small length of rubber hose containing a water-soaked sponge, called a Dampit, is inserted through the f-holes and serves as a humidifier. This keeps the wood components of the cello from drying out. Internally, the cello has two important features: a bass bar , which is glued to the underside of the top of the instrument, and a round wooden sound post ,
12690-412: The introduction to Strawberry Fields Forever ) actually comprises recordings from an alto flute and a soprano flute, which accounts for some of the odd tuning that appears when chords are played. Other sounds such as the brass opted for a layered effect where instruments were recorded within their correct range. Others recorded more recently, such as the bass clarinet opt instead to drop the tuning on
12825-414: The late 19th century were less successful. Electric typewriters developed, up to the 1980s, as "power-assisted typewriters". They contained a single electrical component, the motor. Where the keystroke had previously moved a typebar directly, now it engaged mechanical linkages that directed mechanical power from the motor into the typebar. This was also true of the later IBM Selectric . At Bell Labs , in
12960-505: The legs. The likely predecessors of the violin family include the lira da braccio and the rebec . The earliest surviving cellos are made by Andrea Amati , the first known member of the celebrated Amati family of luthiers . The direct ancestor to the violoncello was the bass violin . Monteverdi referred to the instrument as "basso de viola da braccio" in Orfeo (1607). Although the first bass violin , possibly invented as early as 1538,
13095-493: The lower part of the cello. The tailpiece is the part of the cello to which the "ball ends" of the strings are attached by passing them through holes. The tailpiece is attached to the bottom of the cello. The tailpiece is traditionally made of ebony or another hardwood, but can also be made of plastic or steel on lower-cost instruments. It attaches the strings to the lower end of the cello and can have one or more fine tuners. The fine tuners are used to make smaller adjustments to
13230-451: The lower range of the Mellotron, and so the bottom notes are actually performed on a double bass (His refusal was based on the fact that him playing these notes on his cello would be robbing a double bassist of the session fee. When the double bassist turned up for the next session it was found to be Kilbey with a different instrument, thereby collecting a double fee for both appearances). According to Mellotron author Nick Awde , one note of
13365-529: The lowest notes by pitching them electronically. The Mellotron choir was recorded in two halves: four men in one studio, and four women in another adjacent, thereby allowing for the actual recording of three sounds concurrently. In this, the male singers from the Ted Taylor Choir were allowed to drop the highest notes back to the previous octave as they were considerably out of their natural range. The original Mellotrons were intended to be used in
13500-418: The magnet caused the wire to spin. Ten years later the first electric generator was invented, again by Michael Faraday. This generator consisted of a magnet passing through a coil of wire and inducing current that was measured by a galvanometer. Faraday's research and experiments into electricity are the basis of most of modern electromechanical principles known today. Interest in electromechanics surged with
13635-556: The middle 20th century in Sweden , the United States , Canada , and Great Britain , and these quickly spread to the rest of the world. Electromechanical systems saw a massive leap in progress from 1910-1945 as the world was put into global war twice. World War I saw a burst of new electromechanics as spotlights and radios were used by all countries. By World War II , countries had developed and centralized their military around
13770-424: The model M400 was released, which contained 35 notes (G–F) and a removable tape frame. It sold over 1,800 units. In the early 1970s, hundreds of the instruments were assembled and sold by EMI under exclusive licence. Following a financial and trademark dispute through a US distribution agreement, the Mellotron name was acquired by American-based Sound Sales. Streetly-manufactured instruments after 1976 were sold under
13905-421: The modern instrument in several ways. The neck has a different form and angle, which matches the baroque bass-bar and stringing. The fingerboard is usually shorter than that of the modern cello, as the highest notes are not often called for in baroque music. Modern cellos have an endpin at the bottom to support the instrument (and transmit some of the sound through the floor), while Baroque cellos are held only by
14040-492: The name Novatron . The American Mellotron distributor, Sound Sales, produced their own Mellotron model, the 4-Track, in the early 1980s. At the same time Streetly Electronics produced a road-cased version of the 400 – the T550 Novatron. By the mid-1980s, both Sound Sales and Streetly Electronics suffered severe financial setbacks, losing their market to synthesizers and solid-state electronic samplers , which rendered
14175-417: The open strings are C, G, D, and A (black note heads in the playing range figure above), unless alternative tuning ( scordatura ) is specified by the composer. Some composers (e.g. Ottorino Respighi in the final movement of The Pines of Rome ) ask that the low C be tuned down to a B-flat so that the performer can play a different low note on the lowest open string. The tailpiece and endpin are found in
14310-437: The original design. The Bradleys subsequently met bandleader Eric Robinson , who agreed to help finance the recording of the necessary instruments and sounds. Together with the Bradleys and television celebrity David Nixon (Robinson's son-in-law), they formed a company, Mellotronics, in order to market the instrument. Robinson was particularly enthusiastic about the Mellotron, because he felt it would revitalise his career, which
14445-513: The part in "Strawberry Fields Forever" as "probably the most famous Mellotron figure of all-time". Although producer George Martin was unconvinced by the instrument, describing it "as if a Neanderthal piano had impregnated a primitive electronic keyboard", they continued to compose and record with various Mellotrons for the albums Magical Mystery Tour (1967) and The Beatles (1968, also known as "the White Album"). McCartney went on to use
14580-419: The pitch of the string. The fine tuners can increase the tension of each string (raising the pitch) or decrease the tension of the string (lowering the pitch). When the performer is putting on a new string, the fine tuner for that string is normally reset to a middle position, and then the peg is turned to bring the string up to pitch. The fine turners are used for subtle, minor adjustments to pitch, such as tuning
14715-416: The preferences of their teacher. Bows are also made from other materials, such as carbon fibre—stronger than wood—and fiberglass (often used to make inexpensive, lower-quality student bows). An average cello bow is 73 cm (29 in) long (shorter than a violin or viola bow) 3 cm (1.2 in) high (from the frog to the stick) and 1.5 cm (0.59 in) wide. The frog of a cello bow typically has
14850-422: The recording Variations . Most notably, Pink Floyd included a cello solo in their 1970 epic instrumental " Atom Heart Mother ". Bass guitarist Mike Rutherford of Genesis was originally a cellist and included some cello parts in their Foxtrot album. Established non-traditional cello groups include Apocalyptica , a group of Finnish cellists best known for their versions of Metallica songs; Rasputina ,
14985-586: The recordings on them if played. Although tape samplers had been explored in research studios, the first commercially available keyboard-driven tape instruments were built and sold by California-based Harry Chamberlin . The concept of the Mellotron originated when Chamberlin's sales agent, Bill Fransen, brought two of Chamberlin's Musicmaster 600 instruments to England in 1962 to search for someone who could manufacture 70 matching tape heads for future Chamberlins. He met Frank, Norman, and Les Bradley of tape engineering company Bradmatic Ltd, who said they could improve on
15120-417: The removal of the top. Theoretically, hide glue is weaker than the body's wood, so as the top or back shrinks side-to-side, the glue holding it lets go and the plate does not crack. Cellists repairing cracks in their cello do not use regular wood glue , because it cannot be steamed open when a repair has to be made by a luthier . Traditionally, bows are made from pernambuco or brazilwood . Both come from
15255-562: The research into long distance communication. The Industrial Revolution 's rapid increase in production gave rise to a demand for intracontinental communication, allowing electromechanics to make its way into public service. Relays originated with telegraphy as electromechanical devices were used to regenerate telegraph signals. The Strowger switch , the Panel switch , and similar devices were widely used in early automated telephone exchanges . Crossbar switches were first widely installed in
15390-789: The rim of the instrument but spreads no further. Without purfling, cracks can spread up or down the top or back. Playing, traveling and the weather all affect the cello and can increase a crack if purfling is not in place. The fingerboard and pegs on a cello are generally made from ebony , as it is strong and does not wear out easily. In the late 1920s and early 1930s, the Aluminum Company of America (Alcoa) as well as German luthier G.A. Pfretzschner produced an unknown number of aluminum cellos (in addition to aluminum double basses and violins). Cello manufacturer Luis & Clark constructs cellos from carbon fibre . Carbon fibre instruments are particularly suitable for outdoor playing because of
15525-411: The same species of tree ( Caesalpinia echinata ), but Pernambuco, used for higher-quality bows, is the heartwood of the tree and is darker in color than brazilwood (which is sometimes stained to compensate). Pernambuco is a heavy, resinous wood with great elasticity, which makes it an ideal wood for instrument bows. Horsehair is stretched out between the two ends of the bow. The taut horsehair is drawn over
15660-427: The similar Chamberlin , but could be mass-produced more efficiently. The first models were designed for the home and contained a variety of sounds, including automatic accompaniments. Bandleader Eric Robinson and television personality David Nixon helped promote the first instruments, and celebrities such as Princess Margaret were early adopters. It was adopted by rock and pop groups in the mid to late 1960s. One of
15795-921: The standard repertoire. Other major composers who wrote concertante works for him include Messiaen , Jolivet , Berio , and Penderecki . In addition, Arnold , Barber , Glass , Hindemith , Honegger , Ligeti, Myaskovsky , Penderecki, Rodrigo , Villa-Lobos and Walton wrote major concertos for other cellists, notably for Gaspar Cassadó , Aldo Parisot , Gregor Piatigorsky, Siegfried Palm and Julian Lloyd Webber . There are also many sonatas for cello and piano . Those written by Beethoven , Mendelssohn , Chopin , Brahms , Grieg , Rachmaninoff , Debussy , Fauré , Shostakovich, Prokofiev, Poulenc , Carter , and Britten are particularly well known. Other important pieces for cello and piano include Schumann's five Stücke im Volkston and transcriptions like Schubert 's Arpeggione Sonata (originally for arpeggione and piano), César Franck 's Cello Sonata (originally
15930-473: The stock of available instruments to repair and restore was diminishing, so they decided to build a new model, which became the M4000. The instrument combined the features of several previous models, and featured the layout and chassis of an M400 but with a digital bank selector that emulated the mechanical original in the Mk II. The first notable musician to use the Mellotron was variety pianist Geoff Unwin , who
16065-404: The strength of the material and its resistance to humidity and temperature fluctuations. Luis & Clark has produced over 1000 cellos, some of which are owned by cellists such as Yo-Yo Ma and Josephine van Lier . Above the main body is the carved neck. The neck has a curved cross-section on its underside, which is where the player's thumb runs along the neck during playing. The neck leads to
16200-458: The string sounds contains the sound of a chair being scraped in the background. When the Chamberlin was first developed, the initial recorded sound used was that of three violins, thereby committing the instrument range to G2 to F5, being the range of the violin . Unfortunately, as with the cello, many other instruments did not conform to this range. The noted solo flute (which appears on
16335-410: The strings, while being held roughly parallel to the bridge and perpendicular to the strings, to produce sound. A small knob is twisted to increase or decrease the tension of the horsehair. The tension on the bow is released when the instrument is not being used. The amount of tension a cellist puts on the bow hair depends on the preferences of the player, the style of music being played, and for students,
16470-545: The surroundings and process things such as chemicals , motions and light . One of the first silicon pressure sensors was isotropically micromachined by Honeywell in 1962. An early example of a MEMS device is the resonant-gate transistor, an adaptation of the MOSFET, developed by Harvey C. Nathanson in 1965. During the 1970s to early 1980s, a number of MOSFET microsensors were developed for measuring physical , chemical , biological and environmental parameters. In
16605-435: The tensions of the bridge and strings. Together, the bass bar and sound post transfer the strings' vibrations to the top (front) of the instrument (and to a lesser extent the back), acting as a diaphragm to produce the instrument's sound. Cellos are constructed and repaired using hide glue , which is strong but reversible, allowing for disassembly when needed. Tops may be glued on with diluted glue since some repairs call for
16740-413: The term is usually understood to refer to devices which involve an electrical signal to create mechanical movement, or vice versa mechanical movement to create an electric signal. Often involving electromagnetic principles such as in relays , which allow a voltage or current to control another, usually isolated circuit voltage or current by mechanically switching sets of contacts, and solenoids , by which
16875-473: The versatility and power of electromechanics. One example of these still used today is the alternator , which was created to power military equipment in the 1950s and later repurposed for automobiles in the 1960s. Post-war America greatly benefited from the military's development of electromechanics as household work was quickly replaced by electromechanical systems such as microwaves, refrigerators, and washing machines. The electromechanical television systems of
17010-418: The wood and bending it around forms. The cello body has a wide top bout, narrow middle formed by two C-bouts, and wide bottom bout, with the bridge and F holes just below the middle. The top and back of the cello have a decorative border inlay known as purfling . While purfling is attractive, it is also functional: if the instrument is struck, the purfling can prevent cracking of the wood. A crack may form at
17145-500: Was a large-sized member of viol (viola da gamba) family or the violin ( viola da braccio ) family. The term "violone" today usually refers to the lowest-pitched instrument of the viols, a family of stringed instruments that went out of fashion around the end of the 17th century in most countries except England and, especially, France, where they survived another half-century before the louder violin family came into greater favour in that country as well. In modern symphony orchestras, it
17280-484: Was commonly used as a solo instrument and five-string instruments are occasionally specified in the Baroque repertoire. BWV 1012 (Bach's 6th Cello Suite) was written for 5 string Cello but since its additional High E String is an Octave below the same string on the Violin, anything written for the Violin can be played on the 5 string Cello, sounding an Octave lower than written. Few educational works specifically devoted to
17415-429: Was invented in 1822 by Michael Faraday . The motor was developed only a year after Hans Christian Ørsted discovered that the flow of electric current creates a proportional magnetic field. This early motor was simply a wire partially submerged into a glass of mercury with a magnet at the bottom. When the wire was connected to a battery a magnetic field was created and this interaction with the magnetic field given off by
17550-457: Was most likely inspired by the viol, it was created to be used in consort with the violin. The bass violin was actually often referred to as a " violone ", or "large viola", as were the viols of the same period. Instruments that share features with both the bass violin and the viola da gamba appear in Italian art of the early 16th century. The invention of wire-wound strings (fine wire around
17685-415: Was originally played by Ian McDonald, and subsequently by Robert Fripp upon McDonald's departure. Later member David Cross recalled he did not particularly want to play the Mellotron, but felt that it was simply what he needed to do as a member of the band. Tony Banks bought a Mellotron from Fripp in 1971, which he claimed was previously used by King Crimson, to use with Genesis . He decided to approach
17820-404: Was specifically hired by Robinson in 1962 to promote the use of the instrument. He toured with a Mk II Mellotron and made numerous appearances on television and radio. Unwin claimed that the automatic backing tracks on the Mk II's left-hand keyboard allowed him to provide more accomplished performances than his own basic skills on the piano could provide. The earlier 1960s Mk II units were made for
17955-517: Was then on the wane. He arranged the recording sessions at IBC Studios in London, which he co-owned with George Clouston. The first model to be commercially manufactured was the Mk I in 1963. An updated version, the Mk II, was released the following year which featured the full set of sounds selectable by banks and stations. The instrument was expensive, costing £1,000 (equivalent to £26,449 in 2023), at
18090-399: Was used by Patrick Moraz . The Birotron was a similar concept based around 8-track cartridges , used by Wakeman. Electro-mechanical Electromechanical devices are ones which have both electrical and mechanical processes. Strictly speaking, a manually operated switch is an electromechanical component due to the mechanical movement causing an electrical output. Though this is true,
18225-564: Was writing for cello in the mid 20th century with Concerto No. 1 for Cello and Orchestra (1951), Concerto No. 2 for Cello and Orchestra (1963) and in 1964 composed her Quartet for four cellos. In the 2010s, the instrument is found in popular music , but was more commonly used in 1970s pop and disco music. Today it is sometimes featured in pop and rock recordings, examples of which are noted later in this article. The cello has also appeared in major hip-hop and R & B performances, such as singers Rihanna and Ne-Yo 's 2007 performance at
