The beat the song is built on is one bar, played through bars 13-26, 28-37 and 39-45, and 1 more place -- 23.9% 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 the snare, counted in sixteenth notes. On its own it scores 20 out of 100 -- straightforward -- and the thing that decides that is how much of it falls off the beat.
The whole song is 51 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 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 snare, in 3/4 at 180 BPM, counted in sixteenth notes. It is written out above, and it covers 23.9% of the bars the kit plays.
Bars 13-26, 28-37, 39-45 and 59-77. The time is kept on the toms to start with, and it changes 29 times over the song.
20 out of 100 on its own -- straightforward. The song as a whole is 51 out of 100, a step up from a first song, and the work is in the independence between the hands and the feet.
