Listen back, then keep it or try again.

Song

Your tracks

Layer takes and balance their volume — drag a slider while it's playing to hear the change immediately. Muted tracks are skipped when you record and when you play. Loop passes all start at bar 1, so they stack.

Compose

Start from a writer

Pick whose harmony you want and the app writes a song in that language — drums, bass, piano, guitar and a sung vocal, each as its own track. Key and tempo change every time. Nothing is fixed: mute what you don’t want, delete a part and play it yourself.

Demo

We Never Sleep

Written by the app’s composer in the language of Radiohead — a pedal held under parallel major and minor, chromatic passing tones woven into the vocal line, and a chord borrowed from outside the key roughly a quarter of the time. The verse tune comes back each time it repeats, and every word is sung on its own note, tuned to the melody rather than spoken. Press Compose and it writes a different one.

Harmony

Borrowed chords from outside the key — the ♭VII and the minor iv — written fresh rather than picked from a list

Melody

One verse tune, reused; the chorus sits higher, and the phrase starts a beat before the bar

Middle

The guitar takes the tune where the voice would be, then the last chorus comes back biggest

Vocal

Real speech, retuned one word per note, now with the grammar to make a claim rather than list images
