Soyka shows short films about the Enharmonic Microtonal Organ of
Hans-André Stamm, about the Seminar MICROTONAL MUSIC at Conservatory
Prayner, Vienna, and about rehearsals with microtonal music there.
The organ was built 1979 in Belgium (Schumacher), according the
construction ideas of Martin Vogel (Bonn 1968). Each octava of this
instrument has 48 microtones. The keyboard-system uses the 5th and
the 7th partial-tone e.g. in just-intonation, together with some
enharmonic microtones. The notation is very clear. The special microtonal
keyboard-system of this organ is easy to play, but the instrument
has two manuals with traditional keyboard-system, too. CDs with
new tonal music by Hans-André Stamm and Ulf-Diether Soyka can be
heared. Discussion about methods of composing with this instrument.
