Everything that anyone has ever done, someone is still doing. It’s already been pointed out in Frank’s thread that LPs, CDs, cassettes, and so on will continue to be produced and consumed into foreseeable perpetuity, if only for their fetish value: Buying an album in .mp3 form is a different act than buying it on CD, which in turn is different from buying it on vinyl, and these differences themselves hold meaning for many consumers.
Given the simple arithmetic of these cattle calls—many scores will be sent, only one chosen—rejection is par for the course. It never bothers me, though: I reason that even though there are plenty of criteria a panel of judges might consider in choosing a selection, it’s very difficult for someone who is grossly incompetent to come out on top; if it doesn’t go my way, the person who did snag the performance, commission, or prize probably won it fair and square. It’s not a referendum on how bad my piece is but rather on how great someone else’s is, and that’s fine by me.
If an amateur is writing music with the expectation that it will be performed (and if this expectation is met) the situation gets much more uncomfortable for us professional composers to confront: What separates the amateur, a composer whose music receives program space, from me, a composer whose music receives program space?
Western musicians are accustomed to digesting note material (which is to say dots and lines) first and verbal material later or not at all. In the score of YLEM, for instance, Stockhausen specifies several pitch-classes by name, and of course we were very careful to play the right ones at the right times. “Play a tone for so long until you hear its individual vibrations” is an instruction no less concrete (although perhaps a bit more psychoacoustically challenging) than a B-flat quarter-note in the middle of the treble clef, but it’s not presented in the code that musicians are conditioned to take seriously.
