Let's see if Steve Schwartz statement makes good sense, after a more or
less by rote replacement of "repeat" by "note":

   "What I have been saying is that it takes absolutely no musical
   insight at all to play a note simply because the composer put
   it there.  I want to know what the *musical* reason is - that is,
   based on the music so far and the music in totality and the note
   in itself to be played, what does the note contribute other than
   simply make the work longer?"
