110 bars at 180 BPM -- fast, and 2:30 of it without a break -- on crash, ride, hi-hat, snare, high tom, mid tom, floor tom and kick.
77 out of 100: demanding, mostly on how many notes a second it asks for.
snare through bars 1-8, hi-hat through bars 9-26, snare through bars 27-33, toms through bars 34-36, snare through bars 37-44 and hi-hat through bars 45-48, and 8 more changes after that.
The beat the song is built on is one bar, played through bars 1-3, 5-7 and 9-11, and 6 more places -- 25% of every bar the kit plays. That is the spine of it; everything else is what happens around it.

It cuts the song into 50 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.
180 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.
77 out of 100: demanding, mostly on 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.
110 bars, about 2:30 at the written tempo. The course breaks it into 50 exercises over 16 sittings, about 26 minutes each.
crash, ride, 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.
