86 bars of 4/4 at 120 BPM, about 2:52 of playing, on crash, ride, hi-hat, snare, high tom, mid tom, floor tom and kick.
26 out of 100 -- a fair first song -- with how often it moves around the kit the part that decides it.
ride through bars 1-12, toms through bars 13-14, hi-hat through bars 15-20, kick and crashes through bars 21-22, hi-hat through bars 23-28 and ride through bars 29-68, and 1 more change after that.
The beat the song is built on is one bar, played through bars 3-4, 7-8 and 11-12, and 8 more places -- 32.8% of every bar the kit plays. That is the spine of it; everything else is what happens around it.
