145 bars of 3/4 -- not four -- at 180 BPM, 2:54 of playing on crash, ride, hi-hat, snare, high tom, mid tom, kick and hi-hat foot.
85 out of 100. Hard, and what makes it hard is how many notes a second it asks for.
hi-hat through bars 1-2, ride through bars 3-21, silence through bars 22-26, snare through bars 27-42, ride through bars 43-46 and snare through bars 47-50, and 8 more changes after that.
The beat the song is built on is one bar, played through bars 31-38, 105 and 109, and 8 more places -- 13.4% 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 58 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 3/4, 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.
85 out of 100. Hard, and what makes it hard is how many notes a second it asks for. The beat itself is 59 out of 100; the rest of the number is everything around it.
145 bars, about 2:54 at the written tempo. The course breaks it into 58 exercises over 21 sittings, about 25 minutes each.
crash, ride, hi-hat, snare, high tom, mid tom, kick and hi-hat foot. That is most of a full kit; the part moves around it rather than sitting in one place.
