The beat the song is built on is one bar, played through bars 8, 10-13 and 44, and 14 more places -- 23.4% of every bar the kit plays. This one moves around more than most: the beat is where to start, not the whole job.
It is played on crash, snare and kick, counted in sixteenth notes. On its own it scores 50 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 57 out of 100, so the beat is most of what the song asks for. Get it clean and the rest follows.
The room opens this beat on its simplest reduction, at 120 BPM, and adds the notes back a rung at a time -- 3 of them. Nothing is a matter of opinion: each rung has a tempo to reach and a gate to pass before the next one.
Tempo goes 120, 140 and 160 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 160 BPM, counted in sixteenth notes. It is written out above, and it covers 23.4% of the bars the kit plays.
Bars 8, 10-13, 44 and 52, and 13 more places. The time is kept on the toms to start with, and it changes 13 times over the song.
50 out of 100 on its own -- a step up. The song as a whole is 57 out of 100, a step up from a first song, and the work is in the independence between the hands and the feet.
