The beat the song is built on is one bar, played through bars 21-23, 34-38 and 62-63, and 1 more place -- 22% 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 floor tom and kick, counted in thirty-second notes. On its own it scores 6 out of 100 -- straightforward -- and the thing that decides that is how fine the subdivision is.
The whole song is 32 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 43 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 43, 50 and 57 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 floor tom and kick, in 4/4 at 57 BPM, counted in thirty-second notes. It is written out above, and it covers 22% of the bars the kit plays.
Bars 21-23, 34-38, 62-63 and 78-80. The time is kept on the toms to start with, and it changes 11 times over the song.
6 out of 100 on its own -- straightforward. The song as a whole is 32 out of 100 -- a fair first song -- with how fine the subdivision is the part that decides it.
