The beat the song is built on is one bar, played through bars 13-16, 109-112 and 125-128, and 3 more places -- 20.2% 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 snare and kick, counted in sixteenth notes. On its own it scores 19 out of 100 -- straightforward -- and the thing that decides that is the independence between the hands and the feet.
The whole song is 37 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 75 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 75, 88 and 100 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 snare and kick, in 4/4 at 100 BPM, counted in sixteenth notes. It is written out above, and it covers 20.2% of the bars the kit plays.
Bars 13-16, 109-112, 125-128 and 137-140, and 2 more places. The time is kept on the silence to start with, and it changes 20 times over the song.
19 out of 100 on its own -- straightforward. The song as a whole is 37 out of 100 -- a fair first song -- with how much of it falls off the beat the part that decides it.
