104 bars of 5/4 -- not four -- at 160 BPM, 3:05 of playing on crash, ride, hi-hat, snare, high tom, mid tom, floor tom, kick and hi-hat foot.
77 out of 100: demanding, mostly on the independence between the hands and the feet.
hi-hat through bars 1-2, kick and crashes through bars 3-10, snare through bars 11-16, hi-hat through bars 17-24, ride through bars 25-44 and snare through bars 45-48, and 8 more changes after that.
The beat the song is built on is a 2-bar phrase, played through bars 7, 9-10 and 17, and 7 more places -- 16.4% 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 43 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.
160 BPM, in 5/4, 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 the independence between the hands and the feet. The beat itself is 50 out of 100; the rest of the number is everything around it.
104 bars, about 3:05 at the written tempo. The course breaks it into 43 exercises over 14 sittings, about 26 minutes each.
