The beat the song is built on is one bar, played through bars 26, 28 and 46, and 3 more places -- 19.6% 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 the kick, counted in sixteenth notes. On its own it scores 0 out of 100 -- straightforward -- and the thing that decides that is how fine the subdivision is.
The whole song is 31 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 58 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 58, 67 and 77 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 kick, in 4/4 at 77 BPM, counted in sixteenth notes. It is written out above, and it covers 19.6% of the bars the kit plays.
Bars 26, 28, 46 and 48, and 2 more places. The time is kept on the hi-hat to start with, and it changes 12 times over the song.
0 out of 100 on its own -- straightforward. The song as a whole is 31 out of 100 -- a fair first song -- with the independence between the hands and the feet the part that decides it.
