Two beats, in the time
of three.
Hemiola is an AI music studio built around a single, restless idea — the rhythmic crossing where duple meets triple. Generate, remix and notate hemiolas in seconds.
he·mi·o·la
/ˌhɛmiˈoʊlə/ · noun
“A rhythmic figure in which two beats are played in the time of three, or vice versa — a felt collision of duple and triple time.”
Feel the cross-rhythm.
The dots align only at the downbeat — everywhere else, they argue beautifully. That argument is the hemiola.
A composer's notebook,
wired to a generative engine.
Prompt the pulse
Describe a feel — “waltz colliding with a backbeat” — and Hemiola drafts melodic lines that breathe across the bar.
Notate instantly
Every generation arrives as MIDI, MusicXML and engraved notation. Hand it to your DAW or your players.
Stretch the meter
Slide a single dial from duple to triple. The AI re-phrases your motif, preserving its contour while bending its time.
Stems on demand
Render piano, strings, percussion or a chamber ensemble — each performance reacts to the others in real time.
A short canon of hemiolas.
Six centuries, one rhythmic gesture. Each example opens in the Studio for you to remix.
