The beat the song is built on is one bar, played through bars 27-33, 51-52 and 54-56, and 2 more places -- 16.1% 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 ride, snare and kick, counted in thirty-second notes. On its own it scores 35 out of 100 -- a fair first song -- and the thing that decides that is how fine the subdivision is.
The whole song is 63 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 65 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 65, 75 and 86 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 ride, snare and kick, in 4/4 at 86 BPM, counted in thirty-second notes. It is written out above, and it covers 16.1% of the bars the kit plays.
Bars 27-33, 51-52, 54-56 and 72-73, and 1 more place. The time is kept on the silence to start with, and it changes 12 times over the song.
35 out of 100 on its own -- a fair first song. The song as a whole is 63 out of 100, a step up from a first song, and the work is in the independence between the hands and the feet.
