The beat the song is built on is one bar, played through bars 23, 25 and 27, and 27 more places -- 26.5% of every bar the kit plays. That is the spine of it; everything else is what happens around it.
It is played on crash, ride, snare and kick, counted in thirty-second notes. On its own it scores 27 out of 100 -- a fair first song -- and the thing that decides that is how fine the subdivision is.
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 105 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 105, 123 and 140 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 crash, ride, snare and kick, in 4/4 at 140 BPM, counted in thirty-second notes. It is written out above, and it covers 26.5% of the bars the kit plays.
Bars 23, 25, 27 and 29, and 26 more places. The time is kept on the silence to start with, and it changes 12 times over the song.
27 out of 100 on its own -- a fair first song. 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.
