The beat the song is built on is one bar, played through bars 17-23, 37-39 and 42-45 -- 28% of every bar the kit plays. That is the spine of it; everything else is what happens around it.
It is played on hi-hat, snare and kick, counted in sixteenth notes. On its own it scores 14 out of 100 -- straightforward -- and the thing that decides that is the speed of the hand keeping time.
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 90 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 90, 105 and 120 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 120 BPM, counted in sixteenth notes. It is written out above, and it covers 28% of the bars the kit plays.
Bars 17-23, 37-39 and 42-45. The time is kept on the silence to start with, and it changes 10 times over the song.
14 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.
