The musical score may be prescriptive to the performer, but descriptive
to the listener... ipso facto
Hugh Le Caine's 'Spectrogram' (a 16 channel control voltage source -- the
Coded Music System of 1952) in its 1959 reincarnation used a roll of
paper which went between a very bright light and a row of photocells. The
McGill model had space for 100 channels, although only 16 were installed.
The width of the _black_ (india ink) lines determined the amplitude of
the control voltage. The output voltages were also cross-patchable,
making it possibly an early version of the vocoder.
In this case, the 'score' could have looked like a very crude (16 band)
spectrogram. Istvan Anhalt's Electronic Composition III (Birds and Bells)
was composed from materials created by this instrument and a bank of 16
It seems LeCaine had wanted to provide a way to more easily assemble
works such as Stockhausen's Studie II, by 'drawing' the piece.
