Etüde für Klavier und Ringmodulator
(2011)

Piano, Ringmodulator

ca. 11:00 min

For the performance it is necessary to have an interface which acts like a ring modulator. It should transform the real acoustic signal of the piano in real time and it has to be flexibla with his modulation frequency. I would advise to use a computer program (e.g. Max MSP) which is changing the frequency of the modulator as indicated in the score, when touching a key of the laptop, placed besides the piano. But it can also be done by another person, controling the modulator by and.

The two frequencies (440Hz and 65,4 Hz) naturally have to be adapted to to the tuning of the piano. They have to be set to exactly the same frequency as the notes a‘/low c. It is very important, that the modulated sound from the loudspeakers is set approximately to the same volume, or even a bit louder, than the original live-sound of the piano itself.
