(詳細はaccordion with a melody (right hand) keyboard in the chromatic B-Griff system and a twelve-button diatonic bass keyboard. It is named for a traditional combination of two violins, accordion and contrabass known as a Schrammelquartet – a group that played Schrammelmusik in the Vienna chamber music tradition. In most cases, the instrument has two or three sets of reeds tuned in unison configuration. Its sound is quite different from modern chromatic button accordions (CBAs). This is because it is much smaller and lighter than modern CBAs. The handmade reeds used may also contribute to its sound. == History == The first written notice about the existence of such instruments are from the 1854 Industrial Exhibition in Munich. The Vienna accordion builder Matthäus Bauer was mentioned as one who showed instruments with piano keyboards, and one with a "3 row machine and accidentals", mentioned in combination with the piano accordion. It seems likely that it was unisonoric and chromatic. Matthäus Bauer then held a Vienna privilegium (Patent, 1851). Advertisements in newspapers of the time show pictures of various accordions, that were mostly diatonic, but also piano and 3-row B-Griff configurations. Alfred Mirek mentions the instrument as precursor of the Bayan in his book. The first Bayan was built in 1870. By 1890 the Vienna "Harmonika" builders produced a very large range of instrument types. In 1900 there were 72 accordion builders in Vienna. They also sold copies of English concertinas, German concertinas and bandoneons. Some documented names of Vienna accordion builders that were building instruments over two generations are: Reisinger, Edmund Hochholzer, Josef Trimmel, Pospisil, Bauer, Pick, Adolf Regelstein, Franz Kuritka, Josef Barton, Budowitz; many more were not documented. Some instruments at that time had up to 46 chromatic bass buttons, some had an early version left hand bass with mechanics similar to the modern Stradella Bass, or only 36 buttons with unison single notes. But the usual Schrammelharmonika had only 12 bisonoric bass buttons. This was not a limitation, because a versatile musician could combine two or more buttons at the same time and so obtain a great variety of chords including seventh and diminished. The idea of arranging the buttons in B-Griff order goes back to a musician named Franz Walter. The oldest known and still usable instrument dates from 1874. The first instruments had fewer buttons on the treble side - 46, 49, and later 52 Buttons on three rows. After 1954 few such instruments were produced in Vienna.
