The beat the song is built on is one bar, played through bars 14, 16-17 and 20-27, and 3 more places -- 23.5% 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 hi-hat, snare and kick, counted in sixteenth notes. On its own it scores 40 out of 100 -- a fair first song -- and the thing that decides that is the speed of the hand keeping time.
The whole song is 45 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 135 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 135, 158 and 180 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 hi-hat, snare and kick, in 4/4 at 180 BPM, counted in sixteenth notes. It is written out above, and it covers 23.5% of the bars the kit plays.
Bars 14, 16-17, 20-27 and 37-42, and 2 more places. The time is kept on the silence to start with, and it changes 11 times over the song.
40 out of 100 on its own -- a fair first song. The song as a whole is 45 out of 100, a step up from a first song, and the work is in the independence between the hands and the feet.
