Four dice on a felt table. Each die picks a different element of a four-bar phrase. Roll, the page plays the phrase. Re-roll, a different phrase plays. Different every time, always in key.
Tap a die to lock it before rolling. Locked dice keep their value.
What each die means
Die 1 — Key. 1 → C major · 2 → G major · 3 → D major · 4 → A minor · 5 → E minor · 6 → C pentatonic
Die 3 — Rhythm. Six four-bar rhythmic patterns: straight quarters, syncopated 8ths, dotted, triplet feel, dense fills, sparse long notes.
Die 4 — Contour. Melodic shape: ascending, descending, arch, valley, zigzag, drone-around-tonic.
Every combination produces a valid 4-bar phrase in the chosen key — 6⁴ = 1,296 possible phrases. Lock a die you like, roll the rest, and you can ratchet toward a phrase you keep.
