Tool · Odd meters, polyrhythmic independence, and a hypnotic, orchestrated kit.

Fibonacci grouping

Grouping beats in a sequence such as 1-1-2-3-5-8, as heard in the Lateralus verse.

Practise: Count and play a groove that adds one beat per phrase following a fibonacci-style sequence.

Workout

Linear groove weave

A groove where kick, snare and hi-hat notes never land together, creating constant forward motion.

Practise: Build a one-bar linear pattern where no two limbs ever strike on the same subdivision.

Ostinato foot independence

A repeating foot pattern maintained independently while the hands play a different phrase.

Practise: Set a simple repeating kick or hi-hat foot ostinato and layer a contrasting hand pattern on top.

Workout

Polyrhythmic layering

Playing two different groupings simultaneously, such as 3 against 4, across different limbs.

Practise: Practise 3-against-4 slowly with a metronome, isolating each limb before combining them.

Metric modulation shift

Smoothly shifting the felt pulse from one meter or subdivision to another mid-song.

Orchestrated kit tour

Using the full extended kit, including gongs, chimes and auxiliary percussion, for texture.

Practise: Play a simple groove while adding one auxiliary percussion texture per repeat around the kit.

Workout

Hypnotic repetition build

Sustaining a repeated pattern over many bars while gradually building dynamics and intensity.

Practise: Loop a single groove for five minutes, gradually increasing dynamics without changing the pattern.

A fill that spans an odd-meter bar and resolves cleanly back onto the downbeat of the next phrase.

Practise: Practise a fill that fills exactly one 7/8 or 5/4 bar and lands cleanly on the next bar's one.
