What is AI piano transcription?

AI piano transcription is the automatic conversion of a piano recording into written music: which keys were pressed, when, for how long, and how hard. A neural network trained on piano audio estimates every note event, and a notation pipeline turns those events into an engraved score with a detected key signature and a grand staff split into right and left hand.

The hard part is polyphony. A piano piece is almost never one note at a time — it is chords under a melody, overlapping pedal tones, two independent hands. Simple pitch trackers collapse this into a single guessed line; a polyphonic transcription model reports simultaneous notes separately, which is the difference between a lead sheet caricature and a usable draft of the actual piece.

Treat the output as a strong first draft, not a finished edition. Transcription is estimation: fast runs and dense pedal can produce an occasional extra or merged note. The draft is still hours faster than starting from silence — correct it in any notation editor via the MusicXML export.

What you get from a piano transcription

Engraved sheet music in the browser

The score renders on the page — key signature, tempo mark, treble and bass staves. Read it immediately; no notation software needed to see the result.

Both hands, split automatically

Notes below middle C go to the bass clef, notes above to the treble — the standard grand-staff layout a pianist expects to read.

Key signature detected

The pipeline weighs every note by length and strength to pick the key, so a piece in G major is spelled with its sharp — not drowned in accidentals.

MIDI with the performance intact

The .mid keeps your real timing and dynamics unquantized — drop it into any DAW and the feel of the take survives.

MusicXML for your notation app

Open the .musicxml in MuseScore, Sibelius, Finale or Dorico to edit, transpose and publish the score.

Print or save as PDF

One click opens a print-ready copy of the engraved score — save it as PDF or put it straight on the music stand.

How accurate is it on piano?

Real numbers from the engine (basic-pitch, Spotify Research), measured on reference audio — not marketing copy. We publish them because you should know what to expect before spending a credit.

Single melody line	92% note F1	Clean solo lines transcribe almost perfectly.
Polyphonic piano (chords + both hands)	74% note F1	The realistic case for full pieces — a strong draft that needs light correction.
Bass register	Full range	Left-hand notes down to the bottom of the keyboard are captured — many online converters silently drop them.

Recording quality matters more than anything else: a clean, close-miked or line-in recording of just the piano will always beat a phone capture across the room.

Who uses AI piano transcription

Pianists learning by ear

Turn a performance you love into a readable draft score instead of scrubbing the recording bar by bar.

Piano teachers

Make a printable sheet from a recording of a piece a student wants to learn — at a level of detail you can then simplify.

Composers at the piano

Improvise first, notate later: record the idea, transcribe it, and keep composing from the draft score.

Producers sampling piano

Get the MIDI of a piano phrase to re-voice with any instrument, with the original timing preserved.

How AI piano transcription works

1. Upload piano audio
MP3, WAV, FLAC, AIFF, OGG or M4A — up to 10 minutes per file on the free tier. Solo piano gives the cleanest score.
2. The AI transcribes every note
A neural model estimates pitches, onsets and dynamics — polyphonically, so chords and both hands come through. A cleanup pass removes overtone ghosts.
3. Read, print or export
The engraved score renders on the page. Print it, save a PDF, or download MIDI and MusicXML to keep working.

AI piano transcription FAQ

Can it transcribe both hands at once?

Yes. The model is polyphonic, so simultaneous notes are detected separately, and the notation pipeline splits them onto a grand staff — notes below middle C to the bass clef, above it to the treble. Very dense pedal passages may still merge some inner voices.

How accurate is the transcription?

On reference audio the engine scores 92% note F1 on single lines and 74% on polyphonic piano. In practice that means a clean recording gives you a score that is right in its bones and needs light correction — not a finished edition, and not a random guess either.

Why does my score show a few extra notes?

A piano note is rich in overtones, and the model occasionally reports a strong overtone as its own note. A cleanup pass removes most of these automatically; the few that survive are easy to delete in a notation editor via the MusicXML export.

Does it work on songs with vocals or a band?

It will transcribe everything it hears — vocals and accompaniment included — into one piano part. For a piano score of the piano part, use a recording where the piano is alone or clearly dominant.

Is the piano transcription free?

Sign-up is free and includes 10 credits; one transcription costs one credit. There is no time-limited demo watermark — a credit buys the full result: engraved score, PDF printing, MIDI and MusicXML.

What do I get to download?

Three things: the engraved score to print or save as PDF, a standard MIDI file with your unquantized performance, and MusicXML that opens in MuseScore, Sibelius, Finale or Dorico for editing.
