If the note events are adjusted behind the scenes to such an extent,
then the dancers are not playing the notes in the sense that a
musician would. These "adjusting" functions would seem to represent
the musical composition and a great deal of the musical performance.
Let me turn this example on its head: if somebody were to design a
system allowing "anybody to choreograph", featuring a lifelike
simulated dancer, plus a few simple controls marked "head, left arm,
right arm" and so on, and if there were "adjustment functions" which
would take a novice's input on these controls in order to make the
movement coherent, smooth and articulate, would any novice now be a
choreographer?
