The beat the song is built on is one bar, played through bars 28-38 and 56-65 -- 21% 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 hi-hat, 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 44 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 83 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 83, 96 and 110 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, in 4/4 at 110 BPM, counted in sixteenth notes. It is written out above, and it covers 21% of the bars the kit plays.
Bars 28-38 and 56-65. The time is kept on the silence to start with, and it changes 15 times over the song.
0 out of 100 on its own -- straightforward. The song as a whole is 44 out of 100 -- a fair first song -- with the independence between the hands and the feet the part that decides it.
