164-603: Grotrian-Steinweg , known as Grotrian in the US, is a German manufacturer of prestige pianos . The company is based in Braunschweig , Germany, commonly known as Brunswick in English. Grotrian-Steinweg makes premium grand pianos and upright pianos . Grotrian-Steinweg's history dates back to 1835 when the first Steinweg piano factory was built by Heinrich Engelhard Steinweg (later known as Henry Steinway after his emigration to
328-551: A firestorm which spread from the Hauptbahnhof (main railway station) and quickly moved south-east, completely destroying entire boroughs such as Hammerbrook , Billbrook and Hamm South . Thousands of people perished in these densely populated working class boroughs. The raids, codenamed Operation Gomorrah by the RAF , killed at least 42,600 civilians; the precise number is not known. About one million civilians were evacuated in
492-532: A free imperial city of the Holy Roman Empire . Before the 1871 unification of Germany , it was a fully sovereign city state , and before 1919 formed a civic republic headed constitutionally by a class of hereditary Grand Burghers or Hanseaten . Beset by disasters such as the Great Fire of Hamburg , North Sea flood of 1962 and military conflicts including World War II bombing raids ,
656-561: A grand piano , the frame and strings are horizontal, with the strings extending away from the keyboard. The action lies beneath the strings and uses gravity as its means of return to a state of rest. Grand pianos range in length from approximately 1.5–3 m (4 ft 11 in – 9 ft 10 in). Some of the lengths have been given more-or-less customary names, which vary from time to time and place to place, but might include: All else being equal, longer pianos with longer strings have larger, richer sound and lower inharmonicity of
820-587: A loudspeaker . The electric pianos that became most popular in pop and rock music in the 1960s and 1970s, such as the Fender Rhodes use metal tines in place of strings and use electromagnetic pickups similar to those on an electric guitar . The resulting electrical, analogue signal can then be amplified with a keyboard amplifier or electronically manipulated with effects units . In classical music, electric pianos are mainly used as inexpensive rehearsal or practice instruments. Electric pianos, particularly
984-410: A pedal keyboard at the base, designed to be played by the feet. The pedals may play the existing bass strings on the piano, or rarely, the pedals may have their own set of bass strings and hammer mechanisms. While the typical intended use for pedal pianos is to enable a keyboardist to practice pipe organ music at home, a few players of pedal piano use it as a performance instrument. Wadia Sabra had
1148-526: A precedent in describing " initial interest confusion ": that the brand Grotrian-Steinweg could cause piano buyers to temporarily confuse its brand with the brand Steinway & Sons. The court ordered Grotrian-Steinweg to stop selling pianos in the US under the "Steinweg" name. Afterward, the company formed a business entity named Grotrian Piano Company to sell pianos in North America. On 13 January 1803, Georg Friedrich Karl Grotrian, called Friedrich,
1312-590: A quarter tone apart. By 1927, Grotrian-Steinweg was making about 3,000 pianos annually. This number dropped significantly in the 1930s during the Great Depression ; fewer than 500 pianos were made in 1931, and the workforce was reduced to less than 200. Kurt Grotrian had become seriously ill in the late 1920s, and in 1928 he made his two sons Erwin (1899–1990) and Helmut (1900–1977) shareholders. In 1929, Kurt Grotrian died of complications from his old war wound. Willi Grotrian died in 1931. In World War II ,
1476-486: A "peace cigar" and Grotrian-Steinweg subsequently stopped using the names "Steinweg" and "Grotrian-Steinweg" in the US. In 1930 the Delaware corporation was dissolved, and in the next three years exports from Grotrian-Steinweg to the US decreased then halted completely. In 1950, Grotrian-Steinweg relinquished its old 1926 trademark application, which had never been published. In 1961, Knut Grotrian-Steinweg (b. 1935) joined
1640-408: A Dutchman, Americus Backers , to design a piano in the harpsichord case—the origin of the "grand". This was achieved by about 1777. They quickly gained a reputation for the splendour and powerful tone of their instruments, with Broadwood constructing pianos that were progressively larger, louder, and more robustly constructed. They sent pianos to both Joseph Haydn and Ludwig van Beethoven , and were
1804-414: A built-in amp and speaker). Alternatively, a person can play an electronic piano with headphones in quieter settings. Digital pianos are also non-acoustic and do not have strings or hammers. They use digital audio sampling technology to reproduce the acoustic sound of each piano note accurately. They also must be connected to a power amplifier and speaker to produce sound (however, most digital pianos have

Digital pianos can include sustain pedals, weighted or semi-weighted keys, multiple voice options (e.g., sampled or synthesized imitations of electric piano, Hammond organ , violin , etc.), and MIDI interfaces. MIDI inputs and outputs connect a digital piano to other electronic instruments or musical devices. For example,
2132-633: A contract between Henry III and Hamburg's traders allowed them to establish a hanse in London. This was the first time in history that the word hanse was used for the trading guild of the Hanseatic League . In 1270, the solicitor of the senate of Hamburg , Jordan von Boitzenburg , wrote the first description of civil, criminal and procedural law for a city in Germany in the German language,
2296-483: A digital piano's MIDI out signal could be connected by a patch cord to a synth module , which would allow the performer to use the keyboard of the digital piano to play modern synthesizer sounds. Early digital pianos tended to lack a full set of pedals, but the synthesis software of later models such as the Yamaha Clavinova series synthesised the sympathetic vibration of the other strings (such as when
2460-639: A district in Hamburg called the Portugiesenviertel [ de ] (Portuguese quarter) where many Portuguese people settled and which has a variety of Portuguese restaurants, cafes and shops that attract many tourists. There are several statues, squares and streets in Hamburg that are named after Portuguese historical figures. These include the Vasco da Gama statue on the Kornhaus bridge, which
2624-476: A familiar instrument in the Western world. The piano was based on earlier technological innovations in keyboard instruments . Pipe organs had been used since antiquity, and as such the development of pipe organs enabled instrument builders to learn about creating keyboard mechanisms for sounding pitches . The first string instruments with struck strings were the hammered dulcimers , which were introduced in
2788-406: A family member play a simplified version . The piano is widely employed in classical , jazz , traditional and popular music for solo and ensemble performances, accompaniment, and for composing , songwriting and rehearsals. Despite its weight and cost, the piano's versatility, the extensive training of musicians, and its availability in venues, schools, and rehearsal spaces have made it
2952-636: A few decades of use. Beginning in 1961, the New York branch of the Steinway firm incorporated Teflon , a synthetic material developed by DuPont , for some parts of its Permafree grand action in place of cloth bushings, but abandoned the experiment in 1982 due to excessive friction and a "clicking" that developed over time; Teflon is "humidity stable" whereas the wood adjacent to the Teflon swells and shrinks with humidity changes, causing problems. More recently,
3116-563: A figure of about 143,200 Muslim migrants in Hamburg, making up 8.4% percent of the population. As of 2021 , there were more than 50 mosques in the city, including the Ahmadiyya run Fazle Omar Mosque , which is the oldest in the city, and which hosts the Islamic Centre Hamburg . A Jewish community also exists. As of 2022, around 2,500 Jews live in Hamburg. The city of Hamburg is one of 16 German states , therefore
3280-572: A form of piano wire made from cast steel ; it was "so superior to the iron wire that the English firm soon had a monopoly." A better steel wire was developed in 1840 by the Viennese firm Martin Miller, and a period of innovation and intense competition ensued, with rival brands of piano wire being tested against one another at international competitions, leading ultimately to the modern form of piano wire. Several important advances included changes to
3444-525: A harmonic produced from three octaves below. This lets close and widespread octaves sound pure, and produces virtually beatless perfect fifths . This gives the concert grand a brilliant, singing and sustaining tone quality—one of the principal reasons that full-size grands are used in the concert hall. Smaller grands satisfy the space and cost needs of domestic use; as well, they are used in some small teaching studios and smaller performance venues. Upright pianos, also called vertical pianos, are more compact with

#17327730681043608-478: A lower octave's corresponding sharp overtone rather than to a theoretically correct octave. If octaves are not stretched, single octaves sound in tune, but double—and notably triple—octaves are unacceptably narrow. Stretching a small piano's octaves to match its inherent inharmonicity level creates an imbalance among all the instrument's intervallic relationships. In a concert grand, however, the octave "stretch" retains harmonic balance, even when aligning treble notes to
3772-531: A majority interest in Grotrian-Steinweg was purchased by Parsons Music Group , a company based in Hong Kong. The Grotrian family will remain represented in the group of shareholders. Annually, the company produces about 500 upright pianos in six sizes and 100 grand pianos in five sizes. Some 20 concert grands are made per year—each one requiring 8 months of manufacture. In 2010, the company issued
3936-613: A massive, strong, cast iron frame. Also called the "plate", the iron frame sits atop the soundboard , and serves as the primary bulwark against the force of string tension that can exceed 20 tons (180 kilonewtons) in total for a modern grand piano. The single piece cast iron frame for square piano was patented in 1825 in Boston by Alpheus Babcock , combining the metal hitch pin plate (1821, claimed by Broadwood on behalf of Samuel Hervé) and resisting bars (Thom and Allen, 1820, but also claimed by Broadwood and Érard). Babcock later worked for
4100-417: A microtone piano manufactured by Pleyel in 1920. Abdallah Chahine later constructed his quartertone "Oriental piano" with the help of Austrian Hofmann . With technological advances , amplified electric pianos (1929), electronic pianos (1970s), and digital pianos (1980s) have been developed. The first electric pianos from the late 1920s used metal strings with a magnetic pickup , an amplifier and
4264-400: A musical device exploited by Liszt. When the invention became public, as revised by Henri Herz , the double escapement action gradually became standard in grand pianos and is still incorporated into all grand pianos currently produced in the 2000s. Other improvements of the mechanism included the use of firm felt hammer coverings instead of layered leather or cotton. Felt, which Jean-Henri Pape

Many carpet businesses in Speicherstadt are operated by Afghan traders, with Hamburg still a global leader in the trade of oriental rugs. Hamburg residents with a foreign citizenship as of 31 December 2016 is as follows: As elsewhere in Germany, Standard German
4592-441: A piano are made of a steel core wrapped with one or two layers of copper wire, to increase their mass whilst retaining flexibility. If all strings throughout the piano's compass were individual (monochord), the massive bass strings would overpower the upper ranges. Makers compensate for this with the use of double (bichord) strings in the tenor and triple (trichord) strings throughout the treble. The plate (harp), or metal frame, of
4756-439: A piano are made of materials selected for strength and longevity. This is especially true of the outer rim, which is most commonly made of hardwood , typically hard maple or beech , and its massiveness serves as an essentially immobile object from which the flexible soundboard can best vibrate. According to Harold A. Conklin, the purpose of a sturdy rim is so that, "... the vibrational energy will stay as much as possible in
4920-476: A piano can be played acoustically, or the keyboard can be used as a MIDI controller, which can trigger a synthesizer module or music sampler . Some electronic feature-equipped pianos such as the Yamaha Disklavier electronic player piano, introduced in 1987, are outfitted with electronic sensors for recording and electromechanical solenoids for player piano-style playback. Sensors record the movements of
5084-419: A piano is usually made of cast iron. A massive plate is advantageous. Since the strings vibrate from the plate at both ends, an insufficiently massive plate would absorb too much of the vibrational energy that should go through the bridge to the soundboard. While some manufacturers use cast steel in their plates, most prefer cast iron. Cast iron is easy to cast and machine, has flexibility sufficient for piano use,

5248-471: A piano. An inventory made by his employers, the Medici family, indicates the existence of a piano by 1700. The three Cristofori pianos that survive today date from the 1720s. Cristofori named the instrument un cimbalo di cipresso di piano e forte ("a keyboard of cypress with soft and loud"), abbreviated over time as pianoforte , fortepiano , and later reduced to only piano . Cristofori's great success
5412-434: A position in which it is ready to play again almost immediately after its key is depressed, so the player can repeat the same note rapidly when desired. Cristofori's piano action was a model for the many approaches to piano actions that followed in the next century. Cristofori's early instruments were made with thin strings and were much quieter than the modern piano, though they were louder and had more sustain compared to
5576-596: A small number of acoustic pianos in the 2010s are produced with MIDI recording and digital sound module -triggering capabilities, the 19th century was the era of the most dramatic innovations and modifications of the instrument. Modern pianos have two basic configurations, the grand piano and the upright piano, with various styles of each. There are also specialized and novelty pianos, electric pianos based on electromechanical designs, electronic pianos that synthesize piano-like tones using oscillators, and digital pianos using digital samples of acoustic piano sounds. In
5740-491: A special 175-year anniversary model, a 46.5-inch (118 cm) upright called Composé Exclusif , of which 50 were produced. In 2011, Larry Fine opined that modern Grotrian-Steinweg pianos are among the "highest quality"—on par with Bösendorfer , Hamburg-built Steinway and Fazioli , and of a higher quality than New York-built Steinway . In 2017, Grotrian-Steinweg launched the Wilhelm Grotrian brand. Made for
5904-466: A town of around 500 inhabitants. In 1030, King Mieszko II Lambert of Poland burned down the city. Valdemar II of Denmark raided and occupied Hamburg in 1201 and in 1214. The Black Death killed at least 60% of the population in 1350. Hamburg experienced several great fires in the medieval period. In 1189, by imperial charter, Frederick I "Barbarossa" granted Hamburg the status of a Free Imperial City and tax-free access (or free-trade zone ) up
6068-607: A vertical structure of the frame and strings. The mechanical action structure of the upright piano was invented in London in 1826 by Robert Wornum, and upright models became the most popular model for domestic use. Upright pianos take up less space than a grand piano and as such are a better size for use in private homes for domestic music-making and practice. The hammers move horizontally and return to their resting position via springs, which are susceptible to degradation. Upright pianos with unusually tall frames and long strings were sometimes marketed as upright grand pianos, but that label

6888-465: Is misleading. Some authors classify modern pianos according to their height and to modifications of the action that are necessary to accommodate the height. Upright pianos are generally less expensive than grand pianos. Upright pianos are widely used in churches, community centers, schools, music conservatories and university music programs as rehearsal and practice instruments, and they are popular models for in-home purchase. The toy piano , introduced in
7052-580: Is much more resistant to deformation than steel, and is especially tolerant of compression. Plate casting is an art, since dimensions are crucial and the iron shrinks about one percent during cooling. Including an extremely large piece of metal in a piano is potentially an aesthetic handicap. Piano makers overcome this by polishing, painting, and decorating the plate. Plates often include the manufacturer's ornamental medallion. In an effort to make pianos lighter, Alcoa worked with Winter and Company piano manufacturers to make pianos using an aluminum plate during

Since 1897, the seat of the government has been Hamburg City Hall (Hamburg Rathaus), with
9348-535: The Middle Ages in Europe. During the Middle Ages, there were several attempts at creating stringed keyboard instruments with struck strings. By the 17th century, the mechanisms of keyboard instruments such as the clavichord and the harpsichord were well developed. In a clavichord the strings are struck by tangents, while in a harpsichord they are mechanically plucked by quills when the performer depresses

Most notes have three strings, except for the bass, which graduates from one to two. Notes can be sustained when the keys are released by the use of pedals at the base of the instrument, which lift the dampers off the strings. The sustain pedal allows pianists to connect and overlay sound, and achieve expressive and colorful sonority. In

11972-413: The Hamburg region ( Hamburg Metropolitan Region ) is home to 5,107,429 living on 196/km (510/sq mi). There were 915,319 women and 945,440 men in Hamburg. For every 1,000 females, there were 1,033 males. In 2015, there were 19,768 births in Hamburg (of which 38.3% were to unmarried women); 6422 marriages and 3190 divorces, and 17,565 deaths. In the city, the population was spread out, with 16.1% under
12136-784: The Holocaust . By the end of 1942, the Jüdischer Religionsverband in Hamburg was dissolved as an independent legal entity and its remaining assets and staff were assumed by the Reich Association of Jews in Germany (District Northwest). On 10 June 1943, the Reich Security Main Office dissolved the association by a decree. The few remaining employees not somewhat protected by a mixed marriage were deported from Hamburg on 23 June to Theresienstadt , where most of them perished. The city
12300-642: The Lower Elbe into the North Sea. In 1265, an allegedly forged letter was presented to or by the Rath of Hamburg. This charter, along with Hamburg's proximity to the main trade routes of the North Sea and Baltic Sea , quickly made it a major port in Northern Europe. Its trade alliance with Lübeck in 1241 marks the origin and core of the powerful Hanseatic League of trading cities. On 8 November 1266,
12464-715: The River Alster to create lakes. The islands of Neuwerk , Scharhörn , and Nigehörn , 100 kilometres (60 mi) away in the Hamburg Wadden Sea National Park , are also part of the city of Hamburg. The neighbourhoods of Neuenfelde , Cranz , Francop and Finkenwerder are part of the Altes Land (old land) region, the largest contiguous fruit-producing region in Central Europe. Neugraben-Fischbek has Hamburg's highest elevation,
12628-513: The US where he founded Steinway & Sons ). In 1856, Friedrich Grotrian became a partner; in 1865 his son Wilhelm Grotrian and two associates bought the factory and the right to market their pianos as successors to the Steinweg brand. Ensuing generations of Grotrian family members led the company to become one of the finest piano manufacturers in Germany. Grotrian-Steinweg pianos were preferred by some famous pianists, and they received accolades at
12792-489: The US, in addition to a few sold by an independent dealer in New York City. Upon discovering the sales in 1928, Steinway & Sons complained to the distributor and to Grotrian-Steinweg, but in 1929 Grotrian-Steinweg sent 47 pianos to the US. A family representative of Steinway went to Germany to discuss the problem directly with the Grotrian-Steinweg family. Arriving at a private agreement, the two family leaders smoked
12956-418: The aftermath of the raids. While some of the boroughs destroyed were rebuilt as residential districts after the war, others such as Hammerbrook were entirely developed into office, retail and limited residential or industrial districts. The Hamburg Commonwealth War Graves Commission Cemetery is in the greater Ohlsdorf Cemetery in the north of Hamburg. At least 42,900 people are thought to have perished in
13120-489: The age of 18, and 18.3% were 65 years of age or older. 356 people in Hamburg were over the age of 100. According to the Statistical Office for Hamburg and Schleswig-Holstein , the number of people with a migrant background is at 34% (631,246). Immigrants come from 200 countries. 5,891 people have acquired German cititzenship in 2016. In 2016, there were 1,021,666 households, of which 17.8% had children under
13284-403: The age of 18; 54.4% of all households were made up of singles. 25.6% of all households were single parent households. The average household size was 1.8. Hamburg has the largest Portuguese community in Germany with about 30,000 people with Portuguese heritage . Many Portuguese sailors and merchants came to Hamburg beginning in the 15th century due to its port . Since the 1970s, there has been
13448-418: The best of both of the older instruments, combining the ability to play at least as loudly as a harpsichord with the ability to continuously vary dynamics by touch. Cristofori's new instrument remained relatively unknown until an Italian writer, Scipione Maffei , wrote an enthusiastic article about it in 1711, including a diagram of the mechanism, that was translated into German and widely distributed. Most of
13612-645: The boroughs and quarters have been rearranged several times. Each borough is governed by a Borough Council (German: Bezirksversammlung ) and administered by a Municipal Administrator (German: Bezirksamtsleiter ). The boroughs are not independent municipalities: their power is limited and subordinate to the Senate of Hamburg . The borough administrator is elected by the Borough Council and thereafter requires confirmation and appointment by Hamburg's Senate. The quarters have no governing bodies of their own. Since
13776-535: The building. The new partnership paid for the right to use the trademark "C.F. Th. Steinweg Nachf.", meaning, "Successor to C.F. Theodor Steinweg." ( Nachf. is an abbreviation for Nachfolger —German for successor .) The company name became "Grotrian, Helfferich, Schulz, Th. Steinweg Nachf." Wilhelm Grotrian raised two sons in the 1870s: Wilhelm "Willi" Grotrian Jr (1868–1931) and Kurt Grotrian (1870–1929). In New York City, C.F. Theodor Steinweg (H.E. Steinweg's son) changed his name to C.F. Theodore Steinway, and served as
13940-682: The business, Steinway retired to Braunschweig for his last years. He died in 1889, leaving his collection of pianos to the city's museum. The Hamburg factory proved successful in competing against Grotrian-Steinweg—both companies were known for producing premium pianos. In the 1880s, Willi Grotrian studied piano making with Wm. Knabe & Co. in Baltimore, Maryland , and with Pleyel, Wolff et Cie in Paris, France. Kurt Grotrian also studied with piano makers in other countries. Their father Wilhelm Grotrian Sr took Willi with him to Chicago in 1893; there, at
14104-506: The business. He told them, "Lads, build good pianos and the rest will take care of itself." Willi Grotrian methodically set about to improve the systems and standards the Grotrian-Steinweg company used to produce pianos. The Grotrian-Steinweg brand was well known for being of the highest quality: the company was named purveyor to some 30 "Kaisers, Kings and royal houses". The owners Franz Wilhelm Grotrian, Willi Grotrian and Kurt Grotrian were awarded an imperial and royal warrant of appointment to
14268-711: The category due to the prevailing westerlies. Nearby wetlands enjoy a maritime temperate climate. The amount of snowfall has varied greatly in recent decades. In the late 1970s and early 1980s, heavy snowfall sometimes occurred, the winters of recent years have been less cold, with snowfall just a few days per year. The warmest months are June, July, and August, with high temperatures of 20.1 to 22.5 °C (68.2 to 72.5 °F). The coldest are December, January, and February, with low temperatures of −0.3 to 1.0 °C (31.5 to 33.8 °F). The annual extreme temperatures range from −29.1 °C (−20.4 °F) on 13 February 1940, to 40.1 °C (104.2 °F) on 20 July 2022 , and
14432-534: The city embraced Lutheranism , and it received Reformed refugees from the Netherlands and France. When Jan van Valckenborgh introduced a second layer to the fortifications to protect against the Thirty Years' War in the seventeenth century, he extended Hamburg and created a "New Town" ( Neustadt ) whose street names still date from the grid system of roads he introduced. From the autumn of 1696 to
14596-453: The city from most of its hinterland and reduced Hamburg's global trade. Since German reunification in 1990, and the accession of several Central European and Baltic countries into the European Union in 2004, the Port of Hamburg has restarted ambitions for regaining its position as the region's largest deep-sea port for container shipping and its major commercial and trading centre. Hamburg
14760-442: The city has managed to recover and emerge wealthier after each catastrophe. Major regional broadcaster NDR , the printing and publishing firm Gruner + Jahr and the newspapers Der Spiegel and Die Zeit are based in the city. Hamburg is the seat of Germany's oldest stock exchange and the world's oldest merchant bank , Berenberg Bank . Media, commercial, logistical, and industrial firms with significant locations in
14924-487: The city in 1814. Hamburg re-assumed its pre-1811 status as a city-state in 1814. The Vienna Congress of 1815 confirmed Hamburg's independence and it became one of 39 sovereign states of the German Confederation (1815–1866). In 1842, about a quarter of the inner city was destroyed in the " Great Fire ". The fire started on the night of 4 May and was not extinguished until 8 May. It destroyed three churches,
15088-645: The city include multinationals Airbus , Blohm + Voss , Aurubis , Beiersdorf , Lufthansa and Unilever . Hamburg is also a major European science, research, and education hub , with several universities and institutions, including the Deutsches Elektronen-Synchrotron Laboratory DESY . The city enjoys a very high quality of living, being ranked 19th in the 2019 Mercer Quality of Living Survey. Hamburg hosts specialists in world economics and international law, including consular and diplomatic missions such as
15252-552: The city is also home to notable cultural venues such as the Elbphilharmonie and Laeiszhalle concert halls. It gave birth to movements like Hamburger Schule and paved the way for bands including the Beatles . Hamburg is also known for several theatres and a variety of musical shows. St. Pauli 's Reeperbahn is among the best-known European red light districts. Claudius Ptolemy (2nd century AD) reported
15416-462: The city. Hamburg was the departure port for many Germans and Eastern Europeans to emigrate to the United States in the late 19th and early 20th centuries. Trading communities from all over the world established themselves there. A major outbreak of cholera in 1892 was badly handled by the city government, which retained an unusual degree of independence for a German city. About 8,600 died in
15580-506: The city. The company employed about 25 people at this time. Friedrich Grotrian died on 11 December 1860, leaving his share of the company to his son Wilhelm (1843–1917). In 1865, C.F. Theodor Steinweg was needed by his family in New York to help manage Steinway & Sons after his brothers Henry and Charles died. Wilhelm Grotrian joined with two of the piano workmen—Adolph Helfferich and H.D.W. Schulz—to buy out C.F. Theodor Steinweg's share of
15744-511: The clavichord—the only previous keyboard instrument capable of dynamic nuance responding to the player's touch, the velocity with which the keys are pressed. While the clavichord allows expressive control of volume and sustain, it is relatively quiet even at its loudest. The harpsichord produces a sufficiently loud sound, especially when a coupler joins each key to both manuals of a two-manual harpsichord, but it offers no dynamic or expressive control over individual notes. The piano in some sense offers
15908-608: The coalition broke apart on 28 November 2010. On 7 March 2011 Olaf Scholz ( SPD ) became mayor. After the 2015 election the SPD and the Alliance 90/The Greens formed a coalition. Hamburg is made up of seven boroughs (German: Bezirke ) and subdivided into 104 quarters (German: Stadtteile ). There are 181 localities (German: Ortsteile ). The urban organisation is regulated by the Constitution of Hamburg and several laws. Most of
16072-678: The company. In 1966, the company formed a contract with Wurlitzer to sell Grotrian-Steinweg pianos in the US, and the Steinway company brought suit in New York. The case lasted nine years, winding its way through trial courts and district courts, presenting the litigants' counterclaims and appeals. In 1975, the United States Court of Appeals for the Second Circuit heard the arguments in Grotrian, Helfferich, Schulz, Th. Steinweg Nachf. v. Steinway & Sons . Grotrian-Steinweg,
16236-514: The court of Austria-Hungary . In Braunschweig, Grotrian-Steinweg grew to a workforce of 550 by 1913, producing about 1,600 pianos annually. The Grotrian-Steinweg Orchestra was active in Leipzig under the baton of young conductor Hermann Scherchen . Grotrian-dedicated salesrooms were operating in Leipzig, Hanover , Königsberg , Düsseldorf and Berlin. During World War I , Kurt Grotrian left
16400-584: The entry-level piano market, these pianos are designed by Grotrian-Steinweg and built by Parsons Music Group in China . In addition to the Grotrian-Steinweg brand, Grotrian-Steinweg sells the Wilhelm Grotrian brand. Made for the entry-level piano market, Wilhelm Grotrian pianos are designed by Grotrian-Steinweg and built by Parsons Music Group in Yichang , China . Piano A piano
16564-429: The factory and re-established its reputation for quality work. In the 1950s, an annual piano-playing competition was founded by the company, to identify promising young piano students. Grotrian-Steinweg sought to expand into the US in the mid-1960s. Steinway & Sons sued to prevent them from using the Steinweg name, resulting in a 1975 decision by the United States Court of Appeals for the Second Circuit . The case set
16728-621: The factory to serve in the German Army. He was soon wounded and taken prisoner of war . The elder Wilhelm Grotrian died in 1917. Willi Grotrian, his son, led the company but it was greatly reduced in manpower and orders for pianos. After the war, the company resumed as before, expanding sales in 1920 by establishing a London shop under the brand name Grotrian-Steinweg. The workforce increased to 1,000. In 1924, Grotrian-Steinweg built an unusual piano for microtonal music composer Ivan Wyschnegradsky . The piano had three manuals , and strings tuned
16892-418: The first firm to build pianos with a range of more than five octaves: five octaves and a fifth during the 1790s, six octaves by 1810 (Beethoven used the extra notes in his later works), and seven octaves by 1820. The Viennese makers similarly followed these trends; however the two schools used different piano actions: Broadwoods used a more robust action, whereas Viennese instruments were more sensitive. By
17056-677: The first name for the vicinity as Treva . The name Hamburg comes from the first permanent building on the site, a castle which the Emperor Charlemagne ordered constructed in AD 808. It rose on rocky terrain in a marsh between the River Alster and the River Elbe as a defence against Slavic incursion, and acquired the name Hammaburg , burg meaning castle or fort. The origin of the Hamma term remains uncertain, but its location
17220-511: The floor, behind the keyboard and very large sticker action . The short cottage upright or pianino with vertical stringing—made popular by Robert Wornum around 1815—was built into the 20th century. They are informally called birdcage pianos because of their prominent damper mechanism. The oblique upright, popularized in France by Roller & Blanchet during the late 1820s, was diagonally strung throughout its compass. The tiny spinet upright
17384-540: The form of upright, baby grand, and grand piano styles (including a nine-foot concert grand). Reproducing systems have ranged from relatively simple, playback-only models to professional models that can record performance data at resolutions that exceed the limits of normal MIDI data. The unit mounted under the keyboard of the piano can play MIDI or audio software on its CD. Pianos can have over 12,000 individual parts, supporting six functional features: keyboard, hammers, dampers, bridge, soundboard, and strings. Many parts of
17548-448: The framework to resonate more freely with the soundboard, creating additional coloration and complexity of the overall sound. The thick wooden posts on the underside (grands) or back (uprights) of the piano stabilize the rim structure and are made of softwood for stability. The requirement of structural strength, fulfilled by stout hardwood and thick metal, makes a piano heavy. Even a small upright can weigh 136 kg (300 lb), and
17712-415: The higher notes were too soft to allow a full dynamic range. Although this earned him some animosity from Silbermann, the criticism was apparently heeded. Bach did approve of a later instrument he saw in 1747 and even served as an agent in selling Silbermann's pianos. "Instrument: piano et forte genandt"—a reference to the instrument's ability to play soft and loud—was an expression that Bach used to help sell
17876-552: The instrument when he was acting as Silbermann's agent in 1749. Piano making flourished during the late 18th century in the Viennese school , which included Johann Andreas Stein (who worked in Augsburg , Germany) and the Viennese makers Nannette Streicher (daughter of Stein) and Anton Walter . Viennese-style pianos were built with wood frames, two strings per note, and leather-covered hammers. Some of these Viennese pianos had
18040-524: The key. Centuries of work on the mechanism of the harpsichord in particular had shown instrument builders the most effective ways to construct the case, soundboard, bridge, and mechanical action for a keyboard intended to sound strings. The English word piano is a shortened form of the Italian pianoforte , derived from gravecembalo col piano e forte ("harpsichord with soft and loud"). Variations in volume ( loudness ) are produced in response to
18204-477: The keyboard set along the long side. This design is attributed to Christian Ernst Friderici (a pupil of Gottfried Silbermann) in Germany and Johannes Zumpe in England, and it was improved by changes first introduced by Guillaume-Lebrecht Petzold in France and Alpheus Babcock in the United States. Square pianos were built in great numbers through the 1840s in Europe and the 1890s in the United States, and saw
18368-605: The keys, hammers, and pedals during a performance, and the system saves the performance data as a Standard MIDI File (SMF). On playback, the solenoids move the keys and pedals and thus reproduce the original performance. Modern Disklaviers typically include an array of electronic features, such as a built-in tone generator for playing back MIDI accompaniment tracks, speakers, MIDI connectivity that supports communication with computing devices and external MIDI instruments, additional ports for audio and SMPTE input/output (I/O), and Internet connectivity. Disklaviers have been manufactured in
18532-608: The largest German epidemic of the late 19th century, and the last major cholera epidemic in a major city of the Western world. Hamburg was a Gau within the administrative division of Nazi Germany from 1934 until 1945. During the Second World War , the Allied bombing of Hamburg devastated much of the city and the harbour. On 23 July 1943, the Royal Air Force and United States Army Air Force firebombing created
18696-583: The latest territorial reform of March 2008, the boroughs are Hamburg-Mitte , Altona , Eimsbüttel , Hamburg-Nord , Wandsbek , Bergedorf , and Harburg . Hamburg-Mitte ("Hamburg Centre") covers mostly the urban centre of the city and consists of the quarters Billbrook , Billstedt , Borgfelde , Finkenwerder , HafenCity , Hamm , Hammerbrook , Horn , Kleiner Grasbrook , Neuwerk , Rothenburgsort , St. Georg , St. Pauli , Steinwerder , Veddel , Waltershof , and Wilhelmsburg . The quarters Hamburg-Altstadt ("old town") and Neustadt ("new town") are
18860-453: The latter was measured at Hamburg-Neuwiedenthal Meteorological Station, on the same day, a high temperature record of 39.1 °C (102.4 °F) was recorded at Hamburg Airport . View climate chart 1986–2016 or 1960–1990 On 31 December 2016, there were 1,860,759 people registered as living in Hamburg in an area of 755.3 km (291.6 sq mi). The population density was 2,464/km (6,380/sq mi). The metropolitan area of
19024-529: The leader and chief technician of Steinway & Sons for fifteen years. He did not like living in the US, so he kept his home in Braunschweig and traveled back and forth as needed. In 1880 he stopped traveling overseas and started a new Steinway & Sons piano factory in Hamburg , competing with his father's old firm, now called Grotrian-Steinweg, in making pianos for European customers. After establishing
19188-510: The levers to make the hammers strike the strings. The first model, known as the Pianette , was unique in that the tuning pins extended through the instrument, so it could be tuned at the front. The prepared piano , present in some contemporary art music from the 20th and 21st century is a piano which has objects placed inside it to alter its sound, or has had its mechanism changed in some other way. The scores for music for prepared piano specify
19352-408: The modifications, for example, instructing the pianist to insert pieces of rubber, paper, metal screws, or washers in between the strings. These objects mute the strings or alter their timbre. Some Viennese fortepianos incorporated percussion effects, brought into action by levers. These would be used in pieces such as Mozart's Rondo alla Turca . The pedal piano is a rare type of piano that has
19516-500: The most visible change of any type of piano: the iron-framed, over-strung squares manufactured by Steinway & Sons were more than two-and-a-half times the size of Zumpe's wood-framed instruments from a century before. Their overwhelming popularity was the result of inexpensive construction and price, although their tone and performance were limited by narrow soundboards, simple actions and string spacing that made proper hammer alignment difficult. The tall, vertically strung upright grand
19680-499: The name "Steinweg" on its pianos. Steinway lost the case, but in January 1919, Willi and Kurt Grotrian decided to change the family surname to Grotrian-Steinweg to protect the trademark of the family business, in the hope of preventing further lawsuits. In 1925, the company established a sales presence in the US as a Delaware corporation called Grotrian-Steinweg Company. Over the next three years, Grotrian-Steinweg sold only 15 pianos in
19844-410: The next generation of piano builders started their work based on reading this article. One of these builders was Gottfried Silbermann , better known as an organ builder. Silbermann's pianos were virtual copies of Cristofori's, with one important addition: Silbermann invented the forerunner of the modern sustain pedal , which lifts all the dampers from the strings simultaneously. This innovation allows
20008-566: The office of the mayor, the meeting room for the Senate and the floor for the Hamburg Parliament . From 2001 until 2010, the mayor of Hamburg was Ole von Beust , who governed in Germany's first statewide "black-green" coalition, consisting of the conservative CDU Hamburg and the alternative GAL, which are Hamburg's regional wing of the Alliance 90/The Greens party. Von Beust was briefly succeeded by Christoph Ahlhaus in 2010, but
20172-545: The opposite coloring of modern-day pianos; the natural keys were black and the accidental keys white. It was for such instruments that Wolfgang Amadeus Mozart composed his concertos and sonatas , and replicas of them are built in the 21st century for use in authentic-instrument performance of his music. The pianos of Mozart's day had a softer tone than 21st century pianos or English pianos, with less sustaining power. The term fortepiano now distinguishes these early instruments (and modern re-creations) from later pianos. In
20336-467: The period from about 1790 to 1860, the Mozart-era piano underwent significant changes that led to the modern structure of the instrument. This revolution was in response to a preference by composers and pianists for a more powerful, sustained piano sound, which was made possible by the ongoing Industrial Revolution with resources such as high-quality piano wire for strings and precision casting for
20500-437: The pianist to sustain the notes that they have depressed even after their fingers are no longer pressing down the keys. As such, by holding a chord with the sustain pedal, pianists can relocate their hands to a different register of the keyboard in preparation for a subsequent section. Silbermann showed Johann Sebastian Bach one of his early instruments in the 1730s, but Bach did not like the instrument at that time, saying that
20664-439: The pianist's touch (pressure on the keys): the greater the pressure, the greater the force of the hammer hitting the strings and the louder the sound produced and the stronger the attack . Invented in 1700, the fortepiano was the first keyboard instrument to allow gradations of volume and tone according to how forcefully or softly the player presses or strikes the keys, unlike the pipe organ and harpsichord. The invention of
20828-440: The piano factory to his eldest son C.F. Theodor Steinweg (1825–1889) who stayed behind to run it under his own name. Meanwhile, in New York City, the Steinweg family Americanized their surname to Steinway and in 1853 they founded the piano manufacturer Steinway & Sons . Soon after taking ownership of his father's old factory, C.F. Theodor Steinweg moved it to Wolfenbüttel near Braunschweig. Here he met Friedrich Grotrian who
20992-547: The piano is credited to Bartolomeo Cristofori of Padua , Italy, who was employed by Ferdinando de' Medici, Grand Prince of Tuscany , as the Keeper of the Instruments. Cristofori was an expert harpsichord maker and was well acquainted with the body of knowledge on stringed keyboard instruments. This knowledge of keyboard mechanisms and actions helped him to develop the first pianos. It is not known when Cristofori first built
21156-413: The plaintiff, argued that their brand was long established, predating Steinway's in Germany. Steinway & Sons, defendant, counterclaimed that their brand, well known and strongly positive in the US, was weakened by consumers' confusion as to whether the pianos were related. The court affirmed the lower court's ruling in favor of the defendant that piano buyers would be misled in their "initial interest" in
21320-523: The player piano replays the performance using pneumatic devices. Modern equivalents of the player piano include the Bösendorfer CEUS, Yamaha Disklavier and QRS Pianomation, using solenoids and MIDI rather than pneumatics and rolls. A silent piano is an acoustic piano having an option to silence the strings by means of an interposing hammer bar. They are designed for private silent practice, to avoid disturbing others. Edward Ryley invented
21484-1068: The population belonged to the North Elbian Evangelical Lutheran Church , the largest religious body, and 9.9% to the Roman Catholic Church . Hamburg is seat of one of the three bishops of the Evangelical Lutheran Church in Northern Germany and seat of the Roman Catholic Archdiocese of Hamburg . According to the publication Muslimisches Leben in Deutschland (" Muslim life in Germany "), an estimated 141,900 Muslim migrants (from nearly 50 countries of origin) lived in Hamburg in 2008. About three years later (May 2011) calculations based on census data for 21 countries of origin resulted in
21648-563: The post-war work. In 1954, Grotrian-Steinweg initiated a piano-playing competition known as Grotrian-Steinweg Klavierspielwettbewerb , featuring young pianists from music schools. The competition took place in the Braunschweig location of the Hertie department store, with audience applause used as the gauge to determine the winner. In 1968, Grotrian-Steinweg entered into talks with the German National Music Council and
21812-410: The preferred choice when space and budget allow. The grand piano is also considered a necessity in venues hosting skilled pianists. The upright piano is more commonly used because of its smaller size and lower cost. When a key is depressed, the strings inside are struck by felt-coated wooden hammers. The vibrations are transmitted through a bridge to a soundboard that amplifies the sound by coupling
21976-418: The production of massive iron frames that could withstand the tremendous tension of the strings. Over time, the tonal range of the piano was also increased from the five octaves of Mozart's day to the seven octave (or more) range found on today's pianos. Early technological progress in the late 18th century owed much to the firm of Broadwood . John Broadwood joined with another Scot, Robert Stodart, and
22140-469: The quarters were former independent cities, towns or villages annexed into Hamburg proper. The last large annexation was done through the Greater Hamburg Act of 1937, when the cities Altona , Harburg , and Wandsbek were merged into the state of Hamburg. The Act of the Constitution and Administration of Hanseatic city of Hamburg established Hamburg as a state and a municipality. Some of
22304-450: The rim was constructed from several pieces of solid wood, joined and veneered, and European makers used this method well into the 20th century. A modern exception, Bösendorfer (an Austrian manufacturer of high-quality pianos) constructs their inner rims from solid spruce, the same wood that the soundboard is made from, which is notched to allow it to bend; rather than isolating the rim from vibration, their "resonance case principle" allows
22468-429: The second half of the 19th century when its population more than quadrupled to 800,000 as the growth of the city's Atlantic trade helped make it Europe's second-largest port. The Hamburg-America Line , with Albert Ballin as its director, became the world's largest transatlantic shipping company around the start of the 20th century. Shipping companies sailing to South America, Africa, India and East Asia were based in
22632-730: The separation of Church and State, freedom of the press, of assembly and association. Hamburg became a member of the North German Confederation (1866–1871) and of the German Empire (1871–1918), and maintained its self-ruling status during the Weimar Republic (1919–1933). Hamburg acceded to the German Customs Union or Zollverein in 1888, the last (along with Bremen) of the German states to join. The city experienced its fastest growth during
22796-403: The soundboard instead of dissipating uselessly in the case parts, which are inefficient radiators of sound." Hardwood rims are commonly made by laminating thin (hence flexible) strips of hardwood, bending them to the desired shape immediately after the application of glue. The bent plywood system was developed by C.F. Theodore Steinway in 1880 to reduce manufacturing time and costs. Previously,
22960-402: The soundboard is made of spruce boards glued together along the side grain. Spruce's high ratio of strength to weight minimizes acoustic impedance while offering strength sufficient to withstand the downward force of the strings. The best piano makers use quarter-sawn , defect-free spruce of close annular grain, carefully seasoning it over a long period before fabricating the soundboards. This
23124-669: The spring of 1697 the Company of Scotland trading to Africa and the Indies was active in Hamburg. While it was unsuccessful in raising capital locally, it commissioned the construction of four vessels in the port. The Caledonia , a ship of 600 tons with 56 guns, and the Instuaration (later renamed the St. Andrew ), a vessel of 350 tons, were launched in March 1697. Upon the dissolution of
23288-417: The string, such as rust on plain strings and dirt in the windings of bass strings. The higher the partial, the further sharp it runs. Pianos with shorter and thicker string (i.e., small pianos with short string scales) have more inharmonicity. The greater the inharmonicity, the more the ear perceives it as harshness of tone. The inharmonicity of piano strings requires that octaves be stretched , or tuned to
23452-418: The strings are placed in two separate planes, each with its own bridge height, allowed greater length to the bass strings and optimized the transition from unwound tenor strings to the iron or copper-wound bass strings. Over-stringing was invented by Pape during the 1820s and first patented for use in grand pianos in the United States by Henry Steinway Jr. in 1859. Some piano makers added variations to enhance
23616-448: The strings when the sustain pedal is depressed, key release, the drop of the dampers, and simulations of techniques such as re-pedalling. Digital, MIDI-equipped pianos can output a stream of MIDI data, or record and play MIDI format files on digital storage media, similar in concept to a pianola. The MIDI file records the physics of a note rather than its resulting sound and recreates the sounds from its physical properties (e.g., which note
23780-464: The strings. Inharmonicity is the degree to which the frequencies of overtones (known as partials or harmonics ) sound sharp relative to whole multiples of the fundamental frequency. This results from the piano's considerable string stiffness; as a struck string decays, its harmonics vibrate from a point very slightly from its termination toward the center (or more flexible part) of the string. The inharmonicity may also result from imperfections within
23944-513: The surname "Steinweg", unlike the French-, German- and Russian-language versions. This is likely a result of the lawsuit and a wish to minimize liability. In 1974, the Grotrian-Steinweg family built a new factory in northwest Braunschweig on Grotrian-Steinweg Street, very near Bundesautobahn 2 , a major east–west highway. After Helmut and Erwin Grotrian-Steinweg supervised the construction they retired, leaving Helmut's son Knut in charge. This factory
24108-437: The sustain pedal is depressed) and full pedal sets can now be replicated. The processing power of digital pianos has enabled highly realistic pianos using multi-gigabyte piano sample sets with as many as ninety recordings, each lasting many seconds, for each key under different conditions (e.g., there are samples of each note being struck softly, loudly, with a sharp attack, etc.). Additional samples emulate sympathetic resonance of
24272-519: The time of purchase about which manufacturer produced which piano, the court held that a "subliminal confusion" might be present at the initial attraction to the Grotrian-Steinweg brand. The company was forbidden to sell pianos in the US under the name "Steinweg" after 1977. Accordingly, in 1976 Grotrian-Steinweg formed a subsidiary brand for selling pianos in North America: Grotrian Piano Company GmbH. The case
24436-415: The tone of each note, such as Pascal Taskin (1788), Collard & Collard (1821), and Julius Blüthner , who developed Aliquot stringing in 1893. These systems were used to strengthen the tone of the highest register of notes on the piano, which up until this time were viewed as being too weak-sounding. Each used more distinctly ringing, undamped vibrations of sympathetically vibrating strings to add to
24600-550: The tone, except the Blüthner Aliquot stringing , which uses an additional fourth string in the upper two treble sections. While the hitchpins of these separately suspended Aliquot strings are raised slightly above the level of the usual tri-choir strings, they are not struck by the hammers but rather are damped by attachments of the usual dampers. Eager to copy these effects, Theodore Steinway invented duplex scaling , which used short lengths of non-speaking wire bridged by
24764-416: The town hall, and many other buildings, killing 51 people and leaving an estimated 20,000 homeless. Reconstruction took more than 40 years. After periodic political unrest, particularly in 1848 , Hamburg adopted in 1860 a semidemocratic constitution that provided for the election of the Senate, the governing body of the city-state, by adult taxpaying males. Other innovations included the separation of powers,
24928-525: The two piano brands; "a potential Steinway buyer may satisfy himself that the less expensive Grotrian-Steinweg is at least as good, if not better, than a Steinway." The court felt that Grotrian-Steinweg—a brand not very well known in the US—was unfairly given an extra measure of credibility based on the strong reputation that Steinway & Sons had built. Even though premium piano buyers were understood to be sophisticated and knowledgeable, and would not be confused at
25092-408: The way the piano was strung. There are one string for each note in the bass, two for each note in the tenor, and three for each note in the tenor. The use of a Capo d’Astro bar instead of agraffes in the uppermost treble allowed the hammers to strike the strings in their optimal position, greatly increasing that area's power. The implementation of over-stringing (also called cross-stringing ), in which
25256-408: Was a range of such Missingsch varieties, the best-known being the low-prestige ones of the working classes and the somewhat more bourgeois Hanseatendeutsch (Hanseatic German), although the term is used in appreciation. All of these are now moribund due to the influences of Standard German used by education and media. However, the former importance of Low German is indicated by several songs, such as
25420-424: Was arranged like a grand set on end, with the soundboard and bridges above the keys and tuning pins below them. " Giraffe pianos ", " pyramid pianos " and " lyre pianos " were arranged in a somewhat similar fashion, using evocatively shaped cases. The very tall cabinet piano was introduced about 1805 and was built through the 1840s. It had strings arranged vertically on a continuous frame with bridges extended nearly to
25584-635: Was born in Schöningen , Germany. He settled in Moscow to sell pianos, beginning around 1830. He joined a partnership in a small piano making firm based in Saint Petersburg , and included these pianos among the various instruments he sold in his successful Moscow music shop. In Germany, Heinrich Engelhard Steinweg (1797–1871) started making pianos in 1835 from his house in Seesen at the edge of
25748-537: Was designing a stringed keyboard instrument in which the notes are struck by a hammer. The hammer must strike the string but not remain in contact with it, because continued contact would damp the sound and stop the string from vibrating and making sound. This means that after striking the string, the hammer must quickly fall from (or rebound from) the strings. Moreover, the hammer must return to its rest position without bouncing violently (thus preventing notes from being re-played by accidental rebound), and it must return to
25912-411: Was manufactured from the mid-1930s until recent times. The low position of the hammers required the use of a "drop action" to preserve a reasonable keyboard height. Modern upright and grand pianos attained their present, 2000-era forms by the end of the 19th century. While improvements have been made in manufacturing processes, and many individual details of the instrument continue to receive attention, and
26076-494: Was struck and with what velocity). Computer based software, such as Modartt's 2006 Pianoteq , can be used to manipulate the MIDI stream in real time or subsequently to edit it. This type of software may use no samples but synthesize a sound based on aspects of the physics that went into the creation of a played note. By the 2000s, some pianos included an acoustic grand piano or upright piano combined with MIDI electronic features. Such
26240-590: Was suggested by Portuguese residents to bring visibility to the Portuguese community in Hamburg. Hamburg's Afghan community of about 50,000 people is the largest not only in Germany, but also in Europe. They first came to Hamburg in the 1970s before expanding during the Afghan conflict in the 1980s and 1990s where many Afghan migrants chose to live in Hamburg. After 2015 the Afghan population almost doubled due to
26404-659: Was surrendered to British Forces on 3 May 1945, in the Battle of Hamburg , three days after Adolf Hitler 's death. After the Second World War , Hamburg formed part of the British Zone of Occupation ; it became a state of West Germany in 1949. On 16 February 1962, a North Sea flood caused the Elbe to rise to an all-time high, inundating one-fifth of Hamburg and killing more than 300 people. The inner German border – only 50 kilometres (30 mi) east of Hamburg – separated
26568-584: Was the first instance of a court defining the concept now known as " initial interest confusion ". District Judge Lloyd Francis MacMahon wrote: "Misled into an initial interest, a potential Steinway buyer may satisfy himself that the less expensive Grotrian-Steinweg is at least as good, if not better, than a Steinway." MacMahon's idea about the "initial interest" confusion was confirmed by Appeals Court Judge William H. Timbers , writing, "such initial confusion works an injury to Steinway." The English-language section of Grotrian's website does not have any reference to
26732-403: Was the first to use in pianos in 1826, was a more consistent material, permitting wider dynamic ranges as hammer weights and string tension increased. The sostenuto pedal ( see below ), invented in 1844 by Jean-Louis Boisselot and copied by the Steinway firm in 1874, allowed for a wider range of effects. One innovation that helped create the powerful sound of the modern piano was the use of
26896-491: Was traveling for business. In 1854, Friedrich Grotrian received the Müller-Mühlenbein pharmacy as an inheritance from an uncle, so he moved back to Germany to manage it. He joined C.F. Theodor Steinweg's piano company as a partner in 1856. In 1857, C.F. Theodor Steinweg and Grotrian moved the piano factory to Braunschweig, setting up shop in a former mayor's mansion at 48 Bohlweg Street in the inner, medieval part of
