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.

No sound on iPhone? Flick the side switch off silent — iOS mutes web audio when it's on.

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.

Waiting on Three Dots

Written by the app’s composer in the language of 2000s garage rock — a minor tonic pushed under a major IV, driven by two interlocking guitars sampled from a real take: one carries the riff, the other fills the gaps it leaves with low chugging chords. The vocal line swings against a straight rhythm section, leaning into the beat and laying back off it, so the same groove recurs verse to verse instead of walking a metronome. Press Compose and it writes a different one.

Harmony

A minor tonic pushed under a major IV, with two sampled guitars — lead and rhythm — trading the beat rather than doubling each other, over a real sampled bass line

Melody

The opening line comes back as the hook through both verses, sung one word per note, swung against a straight rhythm section

Middle

A contrasting passage lifts the vocal into a different register before the last pass through the hook.

Vocal

Real speech, retuned one word per note, cloned from this writer’s own garage-rock take, with a slight envelope filter easing off the loudest consonants
