The beat the song is built on is one bar, played through bars 11, 43 and 45, and 14 more places -- 15% of every bar the kit plays. This one moves around more than most: the beat is where to start, not the whole job.
It is played on crash, snare and kick, counted in thirty-second notes. On its own it scores 41 out of 100 -- a fair first song -- and the thing that decides that is the independence between the hands and the feet.
The whole song is 66 out of 100, so the beat is not the hard part: what costs you is everything around it, the joins and the fills.
A part this hard is not learned by playing it slowly and hoping. The room opens it on its simplest reduction -- the timekeeper alone, at 66 BPM -- and adds the notes back over 3 rungs, each with a tempo to reach and a gate to pass before the next.
Tempo goes 66, 77 and 88 BPM, and the gate at each one is 8 loops in a row with no wrong note and no wobble in the time.
PRACTISE THIS BEAT →A one-bar groove on crash, snare and kick, in 4/4 at 88 BPM, counted in thirty-second notes. It is written out above, and it covers 15% of the bars the kit plays.
Bars 11, 43, 45 and 50, and 13 more places. The time is kept on the silence to start with, and it changes 18 times over the song.
41 out of 100 on its own -- a fair first song. The song as a whole is 66 out of 100: demanding, mostly on how much of it falls off the beat.
