The beat the song is built on is one bar, played through bars 1-7, 15 and 17-23, and 2 more places -- 24% 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 thirty-second notes. On its own it scores 33 out of 100 -- a fair first song -- and the thing that decides that is how fine the subdivision is.
The whole song is 55 out of 100, so the beat is not the hard part: what costs you is everything around it, the joins and the fills.
The room opens this beat on its simplest reduction, at 124 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 124, 144 and 165 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 165 BPM, counted in thirty-second notes. It is written out above, and it covers 24% of the bars the kit plays.
Bars 1-7, 15, 17-23 and 43-49, and 1 more place. The time is kept on the hi-hat to start with, and it changes 17 times over the song.
33 out of 100 on its own -- a fair first song. The song as a whole is 55 out of 100, a step up from a first song, and the work is in the independence between the hands and the feet.
