The beat-weight channel

Every beat carries a weight.

Colour does in rhythm what it does in tuning. Each beat’s emphasis — downbeat, accent, normal or mute — shows in how tall and saturated it sits. Tap a beat to cycle it; build any odd-meter feel you need.

And when you stack independent pulses, each polyrhythm layer owns a hue from the same 12-tone system as Chordology.

Green is the hit

See the beat land.

The sounding beat flashes green — the same “it landed” green Centz turns when a string is in tune. The tempo and its Italian marking sit dead centre, so you read the pulse without reading a number.

Weighted dots

Downbeat largest in indigo, accents half-lit, normals small, mutes hollow.

The flash

A green ring blooms on whichever beat is sounding, in sync with the click.

Layered pulses

Two cross-rhythms, each in its own hue, so 3-over-4 reads at a glance.

Three ways to watch

Ring. Pendulum. Flash.

A full-screen stage for the music stand or a dark room. Read the beat as a ring, follow the swinging pendulum, or let the whole screen pulse — green on the downbeat.

Tap, count-in & haptics
