The beat the song is built on is one bar, played through bars 9-10, 12-13 and 15-18, and 12 more places -- 85.5% of every bar the kit plays. Learn that one and the song is very nearly finished.
It is played on snare and kick, counted in sixteenth notes. On its own it scores 35 out of 100 -- a fair first song -- and the thing that decides that is how much of it falls off the beat.
The whole song is 45 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 snare and kick, in 4/4 at 120 BPM, counted in sixteenth notes. It is written out above, and it covers 85.5% of the bars the kit plays.
Bars 9-10, 12-13, 15-18 and 20-21, and 11 more places. The time is kept on the kick and crashes to start with, and it changes 6 times over the song.
35 out of 100 on its own -- a fair first song. The song as a whole is 45 out of 100, a step up from a first song, and the work is in the independence between the hands and the feet.
