The beat the song is built on is one bar, played through bars 2-4, 6-8 and 10-12, and 2 more places -- 23.4% 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 the hi-hat, counted in sixteenth notes. On its own it scores 0 out of 100 -- straightforward -- and the thing that decides that is the speed of the hand keeping time.
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 113 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 113, 131 and 150 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 150 BPM, counted in sixteenth notes. It is written out above, and it covers 23.4% of the bars the kit plays.
Bars 2-4, 6-8, 10-12 and 14, and 1 more place. The time is kept on the hi-hat to start with, and it changes 14 times over the song.
0 out of 100 on its own -- straightforward. 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.
