Amadeo

Turn what you hear into sheet music

Heard a tune you want to play? Upload the song, hum it into the microphone or paste a YouTube link. Amadeo picks out the notes, the beat, the key and the chords and writes them on the staff. From there the score is yours: fix what it got wrong, try it on a violin or a harp, and send it to your bandmates with a link.

It all runs in your browser, so your recordings never leave your device.

The melody only suits singing, whistling and solo instruments. Raise the sensitivity for quiet recordings; lower it if the score fills with stray notes.

What happens to your recording

  1. Cleaning up the sound

    The sound is converted to one channel and evened out in volume, whether it came from a file, the microphone or a video.

  2. Finding the notes

    Basic Pitch, a neural network published by Spotify and trained on many instruments and on singing, listens about 86 times a second and hears which notes are sounding, chords included.

  3. Tempo, key and chords

    From those notes Amadeo works out the tempo, the time signature, the key and the chords, and lines every note up with the beat, much as you would when transcribing by ear.

  4. Then it's your score

    No transcription is perfect, so every note can be fixed right on the score. Then hear it on another instrument, save it as MusicXML, MIDI or PDF, or send it with a link.

Then practise it

Play alongPlay your part on a MIDI keyboard or an acoustic piano and each note lights up green, amber or red. Stars and a daily streak help you keep at it. Pro

Falling notesThe score as bars falling onto a keyboard, in time with the music.

Loops and metronomeLoop the bars you keep tripping on, slow them down, and get a measure counted in before you start.

Guitar tablatureStrings and frets worked out for you, under the guitar part.

Tuner and metronomeTune up and set a click before you play.
