The drum beat in Like Eating Glass..

The beat the song is built on is one bar, played through bars 16-18, 20-22 and 26-28, and 3 more places -- 21.2% 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 hi-hat, snare and kick, counted in sixteenth notes. On its own it scores 56 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 66 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.
