The beat the song is built on is one bar, played through bars 5, 9-17 and 20-21, and 14 more places -- 67.2% of every bar the kit plays. Learn that one and the song is very nearly finished.
It is played on crash and kick, counted in sixteenth notes. On its own it scores 17 out of 100 -- straightforward -- and the thing that decides that is how much of it falls off the beat.
The whole song is 38 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 68 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 68, 79 and 90 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 and kick, in 4/4 at 90 BPM, counted in sixteenth notes. It is written out above, and it covers 67.2% of the bars the kit plays.
Bars 5, 9-17, 20-21 and 25-26, and 13 more places. The time is kept on the silence to start with, and it changes 19 times over the song.
17 out of 100 on its own -- straightforward. The song as a whole is 38 out of 100 -- a fair first song -- with the independence between the hands and the feet the part that decides it.
