Or their musical thoughts rarely last beyond one phrase. I would call it musical attention deficit disorder (MADD).
The scary thing is that this MADDness might never stop. Who has time for melody when there are so many toys that need to be featured? You need a high brass feature, a middle brass feature and a low brass feature (perhaps separate features for baris and tubas). Battery and pit need two features each. Electronics, the biggest culprit, must be featured in six different ways:
1. As a transitional crutch - the more transitions you have (i.e. the more you cut up the music into smaller pieces), the more you score there.
2. Soundscape show intro - starting your show with a minute of electronics makes 9 minutes of actual music performance seem like a 10-minute show.
3. Pit amplification.
4. Brass solo amplification - this is now mandatory.
5. Field microphone usage - either using a mic for a sextet/octet, or an array of mics for staged sectional features.
6. Mount mics on instruments and amplify them anytime/anywhere in the show.
After attending to all that, there are only a couple of minutes available for musical thoughts of greater length.
