The beat the song is built on is one bar, played through bars 21-35, 37-51 and 53-68, and 3 more places -- 80% of every bar the kit plays. Learn that one and the song is very nearly finished.
It is played on hi-hat, snare and floor tom, counted in sixteenth notes. On its own it scores 15 out of 100 -- straightforward -- and the thing that decides that is how many notes a second it asks for.
The whole song is 27 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 150 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 150, 175 and 200 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 floor tom, in 4/4 at 200 BPM, counted in sixteenth notes. It is written out above, and it covers 80% of the bars the kit plays.
Bars 21-35, 37-51, 53-68 and 74-87, and 2 more places. The time is kept on the silence to start with, and it changes 8 times over the song.
15 out of 100 on its own -- straightforward. The song as a whole is 27 out of 100 -- a fair first song -- with how often it moves around the kit the part that decides it.
