The drum beat in Symmetry

The beat the song is built on is one bar, played through bars 25-31, 41-48 and 57-59, and 1 more place -- 28% of every bar the kit plays. That is the spine of it; everything else is what happens around it.

It is played on crash, hi-hat, snare and kick, counted in sixteenth notes. On its own it scores 49 out of 100 -- a step up -- and the thing that decides that is how many notes a second it asks for.

The whole song is 46 out of 100, so the beat is most of what the song asks for. Get it clean and the rest follows.

The room opens this beat on its simplest reduction, at 98 BPM, and adds the notes back a rung at a time -- 4 of them. Nothing is a matter of opinion: each rung has a tempo to reach and a gate to pass before the next one.

1. Skeleton. Only the notes that land on a beat. The point is to feel where this bar stands.
2. Kick and snare, whole. The feet and the snare exactly as written, hi-hat pulled back to quarter notes. This is the part to know by heart.
3. Every note, flat. All the notes, but the hi-hat stays closed and nothing is ghosted or accented.
4. As written. Open hi-hat, ghost notes, accents and the crash where they belong.

Tempo goes 98, 115, 133 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.
