String Quartet and Tape
Two of the three sound layers A, B and C are to be reproduced as playback (the playback on the
included CD offers an alternative):
- First, sound layer B is recorded on tape.
- All four instruments are then to be tuned one quarter-tone highter during the following recording of
sound layer A.
- Sound layer C is to be played live.
Of the three ad libitum coloured light parts, Luce 1 and 2 correspond to sound layers A and B, Luce 3
to sound layer C.
