Trois Cent Drones

for toy piano and live-electronics

Listen | Score | Performances | Reviews


This composition is an transformation of the original piano piece Trois cent notes where the resonances of the sympathetic strings of the grand piano are simulated by electronic means. By this, the toy piano becomes a new instrument with an artificial sustain pedal.

In order to perform the piece, please contact the author for sending you the required software for the live-electronics which have to be performed by a second musician.

Although notated solely in quavers, the tempo encompasses a wide range from very slow to extremely fast. Starting with a speed of MM = 50, it gradually accelerates to MM = 400 which equals three “time octaves”, speaking with Karlheinz Stockhausen (cf. his famous article ...how time passes... from 1957). A similar transition also happens in the harmonic domain where the range of three octaves (from F to f”) finally collapses into a single pitch (f'):
