The drum beat in Master of Puppets

The beat the song is built on is one bar, played through bars 40, 48-49 and 51, and 22 more places -- 15.4% 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 46 out of 100 -- a step up -- and the thing that decides that is the independence between the hands and the feet.

The whole song is 64 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 159 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.

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 159, 186 and 212 BPM, and the gate at each one is 8 loops in a row with no wrong note and no wobble in the time.
