126 bars of 3/4 -- not four -- at 75 BPM, 5:52 of playing on crash, ride, hi-hat, snare, high tom, mid tom, floor tom, kick and hi-hat foot.
79 out of 100: demanding, mostly on how much of it falls off the beat.
silence through bars 1-4, hi-hat through bars 5-13, silence through bars 14-16, ride through bars 17-20, hi-hat through bars 21-29 and silence through bars 30-33, and 4 more changes after that.
The beat the song is built on is one bar, played through bars 40, 45-46 and 48-50, and 9 more places -- 22.6% 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 47 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.
75 BPM, in 3/4, with the time kept in thirty-second notes. Slow enough to hear every mistake, which is why the room lets you sit at the written tempo rather than under it.
79 out of 100: demanding, mostly on how much of it falls off the beat. The beat itself is 47 out of 100; the rest of the number is everything around it.
126 bars, about 5:52 at the written tempo. The course breaks it into 47 exercises over 16 sittings, about 25 minutes each.
crash, ride, hi-hat, snare, high tom, mid tom, floor tom, kick and hi-hat foot. That is most of a full kit; the part moves around it rather than sitting in one place.
