i think i have a bit to add to this whole discussion of what is music.
i study music comp at texas christian univ.  i also study a bit of csound with
dr gerry gabel.  there seems to be a problem people are having between
traditional musical tools and using a computer.  several months ago, a
wonderful guy named noel zahler visited and gave some private lessons to us
students.  while i didnt necessarily agree with everything he said, one thing
did strike me.  he has quite some experience with csound and so i asked for a
lesson having to do with csound.  i asked him about whether i should use space
more in the music i showed him.  he said that one of the strong points about
computer music is that it allows control over where music is placed and that i
should use it all the time.  this got me to thinking.
just as you dont use a screwdriver to hammer nails, there are certain things
that are better suited to computer.  if i want to write, say, a string quartet,
i am better off using traditional methods.  and if i wanted to make more
'synthetic' sounds, i would use the computer.  now granted, there is some
crossover, but as a general rule i would not want to use csound to create a
string sound and then program in a note list.  it wiould be better and more
fruitful to use traditional instruments.
i guess what i am trying to say is that each tool has its uses and one should
not be expected to completely take over the functions of another.
