The beat the song is built on is one bar, played through bars 34, 36 and 38, and 28 more places -- 26.3% 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 24 out of 100 -- straightforward -- and the thing that decides that is how many notes a second it asks for.
The whole song is 42 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 kick, in 4/4 at 200 BPM, counted in sixteenth notes. It is written out above, and it covers 26.3% of the bars the kit plays.
Bars 34, 36, 38 and 40, and 27 more places. The time is kept on the silence to start with, and it changes 3 times over the song.
24 out of 100 on its own -- straightforward. The song as a whole is 42 out of 100 -- a fair first song -- with the independence between the hands and the feet the part that decides it.
