The drum beat in Rio

The beat the song is built on is one bar, played through bars 13-15, 17-19 and 21-23, and 9 more places -- 31.4% of every bar the kit plays. That is the spine of it; everything else is what happens around it.

It is played on hi-hat, snare and kick, counted in sixteenth notes. On its own it scores 54 out of 100 -- a step up -- and the thing that decides that is the speed of the hand keeping time.

The whole song is 74 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 91 BPM -- and adds the notes back over 4 rungs, each with a tempo to reach and a gate to pass before the next.

1. 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.
2. Every note, flat. All the notes, but the hi-hat stays closed and nothing is ghosted or accented.
3. As written. Open hi-hat, ghost notes, accents and the crash where they belong.

Tempo goes 91, 107, 124 and 140 BPM, and the gate at each one is 8 loops in a row with no wrong note and no wobble in the time.
