90 bars at 213 BPM -- fast, and 2:02 of it without a break -- on crash, hi-hat, snare, high tom, mid tom, floor tom and kick.
80 out of 100. Hard, and what makes it hard is how many notes a second it asks for.
snare through bars 1-4, toms through bars 5-6, snare through bars 7-49, kick and crashes through bars 50-51, snare through bars 52-62 and toms through bars 63-64, and 3 more changes after that.
The beat the song is built on is one bar, played through bars 38-48 -- 14.3% of every bar the kit plays. This one moves around more than most: the beat is where to start, not the whole job.

It cuts the song into 30 exercises -- the grooves, the fills, and the joins between sections, which is where players actually come off -- and puts them in the order a teacher would. Each one opens on a reduction you can already play and adds the notes back a rung at a time, with a tempo to reach and a gate to pass before the next.
213 BPM, in 4/4, with the time kept in thirty-second notes. At that speed the thirty-second notes are the whole difficulty, so the room will take it down to a quarter of it and climb back.
80 out of 100. Hard, and what makes it hard is how many notes a second it asks for. The beat itself is 60 out of 100; the rest of the number is everything around it.
90 bars, about 2:02 at the written tempo. The course breaks it into 30 exercises over 13 sittings, about 23 minutes each.
crash, hi-hat, snare, high tom, mid tom, floor tom and kick. That is most of a full kit; the part moves around it rather than sitting in one place.
