The beat the song is built on is one bar, played through bars 1-16, 18-19 and 78-80, and 1 more place -- 21.8% 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 hi-hat and snare, counted in sixteenth notes. On its own it scores 10 out of 100 -- straightforward -- and the thing that decides that is the speed of the hand keeping time.
The whole song is 43 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 hi-hat and snare, in 4/4 at 120 BPM, counted in sixteenth notes. It is written out above, and it covers 21.8% of the bars the kit plays.
Bars 1-16, 18-19, 78-80 and 82-84. The time is kept on the hi-hat to start with, and it changes 5 times over the song.
10 out of 100 on its own -- straightforward. The song as a whole is 43 out of 100 -- a fair first song -- with how often it moves around the kit the part that decides it.
