About
One person, one pair of ears.
I'm Antoine Duno. I build Piano to Sheet Music on my own — the transcriber, the site and every article in the journal.
I'm an independent developer. I also build Bullynx, a chart-analysis tool for traders. This site came from a simpler frustration: a piece learned by ear exists only as long as you remember it. Play it once, write it down, and it survives — but writing it down by hand takes an evening, and most people never do it.
So the machine does the tedious half. It hears the notes, lays them on a grand staff, hands you the PDF, the MIDI and the MusicXML, and leaves the musical judgement to you. What it gets wrong, you fix in minutes instead of writing four bars an hour.
There's no team, no support queue and no sales department. Write to me directly at hello@pianotosheetmusic.com.
How the transcription is judged
Tested on real recordings, not clean MIDI
The transcription is measured against piano played in living rooms and recorded on phones — pedal held too long, a bit of room echo, a metronome nobody switched off. Studio-clean test files flatter a transcriber and tell you nothing.
The method comes before the number
When I publish an accuracy claim, I say which recordings it was measured on and how the notes were counted. A single percentage with no method behind it is marketing, not evidence.
The limits are written down
Solo piano transcribes well. Dense pedaled passages, heavy reverb and other instruments in the mix produce notes you will need to fix. You get MusicXML precisely so you can fix them in MuseScore, Sibelius or Dorico.
You hear it before you buy it
The first 30 seconds of any recording are transcribed free. You look at the score, then decide. No file is bought sight unseen.
