01 Set a mood — a slow, sad waltz
Write me a slow waltz that feels a little sad.
Ariosa is an app for composers who'd rather describe a change than draw it. Talk to it, hand-edit when you want, and walk away with a score or leadsheet you'd be proud to share.
Bring your own AI key — currently optimized for Claude, with broader model support arriving.
Apply for the evaluationFive sessions, five different musicians. Pick a tab to see how each one unfolds — every prompt is a message you'd send Ariosa, and the score below is what came back. Hit ▶ Preview under any score to hear it.
No music theory needed — just describe what it should feel like.
A composer building from nothing — melody, bass, harmony, arrangement.
A songwriter sketching at a guitar — start with a simple tune and basic chords, then make the harmony more interesting, then carve out a bridge.
A drummer shaping a groove — start plain, work it into a feel, finish with a fill.
A pianist with a finished piece in 4/4 who wants to feel it in 6/8.
A teacher with a piece written for a pro and a class that needs to play it next month.
Ariosa is in private evaluation. Tell me a little about what you'd like to write and I'll send you a build with a short consent doc.
