i remember coming up with a composition idea in
college which my composition professor rejected.
the concept was to define rhythmic motives and song
structure and leave most note choices to the performers.
(from pitch class sets, chord changes,
etc...)
he said i was "just trying to get out of
the work"
later he wound up using the idea in one of his
compositions...
wheeeeee
interestingly, i have known some very good
performers that were quite nervous about doing improv,
but were ok with "aleatoric" music...
