The beat the song is built on is one bar, played through bars 5, 7 and 9, and 11 more places -- 18.5% 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 and kick, counted in thirty-second notes. On its own it scores 51 out of 100 -- a step up -- and the thing that decides that is how many notes a second it asks for.
The whole song is 100 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 79 BPM -- and adds the notes back over 4 rungs, each with a tempo to reach and a gate to pass before the next.
Tempo goes 79, 94, 108 and 122 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 and kick, in 4/4 at 122 BPM, counted in thirty-second notes. It is written out above, and it covers 18.5% of the bars the kit plays.
Bars 5, 7, 9 and 11, and 10 more places. The time is kept on the hi-hat to start with, and it changes 15 times over the song.
51 out of 100 on its own -- a step up. The song as a whole is 100 out of 100. Hard, and what makes it hard is how many notes a second it asks for.
