As you think about Writing for DrumLine Battle, there's a few rules you'll want to keep in mind:
1. Basically Any Instrument is OK as long as you can carry it on and carry it off. No 23 Octave Marimbas on wheels.
2. There are restrictions on power sources, but guitars and basses with Amps can be used.
3. The performance time needs to be between 90 seconds and 120 seconds. (min half to two minutes).
So, get creative and let's get some music written!
