The BACH.Bow is a convex curved bow which, unlike the ordinary bow, renders possible polyphonic playing on the various strings of the instrument.
In 1989, Michael Bach Bachtischa began developing it, encouraged by John Cage, Dieter Schnebel, Karlheinz Stockhausen, Walter Zimmermann, Mstislav Rostropovich, Janos Starker, Lorin Maazel and Luigi Colani – and since then many pieces have been composed especially for it.
The BACH.Bow is particularly well-suited to the solo repertoire for violin and cello of Johann Sebastian Bach and was specifically developed for this purpose, as it requires both polyphonic and monophonic playing.
In 1996 Michael Bach Bachtischa established the studio BACH.Bogen in Stuttgart, Germany and Wissembourg, France.
