MP3 to piano sheet music

Upload an MP3 of solo piano — or a WAV, M4A, FLAC, or the audio of a video — and PianoToSheet writes it out on a grand staff, with a time signature, key, both hands and note lengths. You can print it as PDF, edit it as MusicXML in MuseScore, Sibelius, Finale or Dorico, or use the MIDI. Preview any 30 seconds free (pieces over 3 minutes get up to 3 sections, never more than a third), then $2.99 once for the whole piece.

What kind of MP3 works

• Solo piano. Acoustic or digital piano, one player. This is what the transcription model was trained for.
• A clean recording. A phone next to the piano is fine; loud talking, a TV or a noisy room is not.
• Up to 10 minutes per file, one piece per file.
• Not suitable: songs with singing, bands, guitar or other instruments mixed in. The model only knows piano and will write wrong notes for everything else.

How accurate is it?

Two different jobs happen. Hearing the notes is now very good: on the first 30 seconds of a studio recording of Bach's Prelude in C, the model found 106 of the 107 notes and added none. Writing them down — choosing barlines, note lengths and which hand plays what — is harder, especially when the player speeds up and slows down. That's why every result comes with one-click fixes for the time signature and barlines, and why you can check any 30 seconds and listen to them before paying.

The examples on the home page are the first 30 seconds of four public-domain recordings, exactly as written by PianoToSheet: a studio grand, a very free-tempo Chopin nocturne, a home-keyboard recording of The Entertainer and a slow Satie piece.

Tips for a better result

• A steady pulse helps most. Even playing, or a quiet metronome, makes the barlines land in the right place.
• Trim talking or long silence at the start of the file.
• If every note looks twice as long or short, use “Halve lengths” or “Double lengths”. If the barlines are off by a beat, use “Move barlines”.
• After paying, you can fix one bar at a time where the player slowed down or paused.
• Recording yourself? See how to record your own playing.

A PDF to print, a MusicXML file to keep editing, a score MIDI (lined up to the beats) and an “as played” MIDI that keeps the exact timing and loudness of the recording. No account, no subscription; files can be re-downloaded for 7 days.
