The beat the song is built on is one bar, played through bars 7-8, 10-12 and 14-16, and 3 more places -- 21.4% 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 hi-hat, snare and kick, counted in thirty-second notes. On its own it scores 32 out of 100 -- a fair first song -- and the thing that decides that is how fine the subdivision is.
The whole song is 53 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 60 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 60, 70 and 80 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 80 BPM, counted in thirty-second notes. It is written out above, and it covers 21.4% of the bars the kit plays.
Bars 7-8, 10-12, 14-16 and 18-19, and 2 more places. The time is kept on the silence to start with, and it changes 10 times over the song.
32 out of 100 on its own -- a fair first song. The song as a whole is 53 out of 100, a step up from a first song, and the work is in the independence between the hands and the feet.
