The drum beat in Metamorphosis (Drum from offical bandscore)

The beat the song is built on is a 2-bar phrase, played through bars 25-29, 31-35 and 37-41, and 17 more places -- 34.3% 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 65 out of 100 -- demanding -- and the thing that decides that is the independence between the hands and the feet.

The whole song is 77 out of 100, so the beat is not the hard part: what costs you is everything around it, the joins and the fills.

A part this hard is not learned by playing it slowly and hoping. The room opens it on its simplest reduction -- the timekeeper alone, at 104 BPM -- and adds the notes back over 4 rungs, each with a tempo to reach and a gate to pass before the next.

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. As written. Open hi-hat, ghost notes, accents and the crash where they belong.

Tempo goes 104, 123, 141 and 160 BPM, and the gate at each one is 8 loops in a row with no wrong note and no wobble in the time.
