Compose melody & chords
This page keeps its own project in this browser (separate from the other music tools).
Chord staff and piano are a simple stack of tones, not piano voice-leading. Rhythm is not on this page yet.
Frequently asked questions
Does this share the song with Melody or Chords?
No. Compose keeps its own project in this browser so harmony practice does not overwrite the shared song.
What are the chord views?
Symbols show chord names and numerals; Staff draws the chord tones; Piano highlights the tones on a keyboard. They show the same chords.
Is it free? Do I need an account?
Yes, it is free, with no sign-up or login and nothing to install.
Does this use AI?
No. Notes and chords come from what you place or from fixed templates.
Does audio get uploaded or saved?
No. Playback is generated in your browser. Project JSON may stay in localStorage. Raw audio is not stored.
