What is Hanon AI — a sheet music scanner built for piano
Hanon AI is GrandScore's sheet music recognition AI. It reads the notes in a photo of printed piano sheet music and turns them into a score you can play and practice.
How it works — three steps
All you need is a photo of the score.
- Photograph — take a photo of printed piano sheet music and upload it. PNG and JPEG are supported.
- Review — Hanon AI reads the page and shows the result as real sheet music. Nothing counts against your quota until you register it.
- Play — register the score and practice with everything GrandScore offers: visual notation, slow tempo, and MIDI.
How to photograph a page that scans cleanly
Recognition accuracy is mostly decided by the photo. If the reading comes back rough, fix these and shoot again. A scan only counts once you register the result, so retaking costs nothing.
- Shoot straight down — at an angle the staves come out as trapezoids and note heights are read at the wrong pitch.
- Keep shadows off the page — your hand or the phone's shadow across the staff degrades recognition in exactly that region. Window light or a lamp facing the page works.
- Fit the whole page in frame — include the left and right ends of the staves and the bar lines. Cropped edges mean lost measures.
- Flatten the page — curvature in the gutter of a bound book bends the staves near the spine.
- Check focus — ledger lines and accidentals are thin marks. Zoom in on your own photo before uploading and confirm they are still legible.
If your score is a PDF
Uploads are images, so a PDF needs one extra step. Images made directly from a PDF have no perspective distortion and no shadows, so they usually read more reliably than a photograph.
- Open the PDF and go to the page you want to read.
- Export that page as PNG or JPEG, or zoom it to fill the screen and take a screenshot.
- Upload the resulting image. For a multi-page piece, prepare one image per page.
Play sheet music from an image, photo, or screenshot — what comes back
The result is a score, not an audio file. Hanon AI reads note heads, rhythms, clefs, and key and time signatures out of the image and rebuilds them as notation. That is why you can then slow the piece down, play one hand at a time, and loop a single passage — an audio rendering would only let you listen.
In the browser, or in the iPhone & iPad app
Hanon AI runs in the browser. On a computer or a phone, open piano.grand-score.com/ai and it is ready. GrandScore is also available as an iPhone and iPad app.
GrandScore for iPhone & iPad →More than an AI sheet music player — it becomes your practice app
Most sheet music scanner apps play the score back and stop there. In GrandScore, the score you scanned becomes something you practice with:
- Visual guidance that shows exactly which keys to press, and when
- Slow tempo for careful practice
- One-hand practice — right or left hand alone
- Partial playback to loop the hard measures
- MIDI keyboard connection with real-time feedback

Curious how it works? The technology is called OMR
The technology that reads sheet music from an image is called OMR — Optical Music Recognition. We explain how it differs from text OCR and how the pipeline works in a separate article.

FAQ
Is there an AI that reads sheet music?
Yes. Hanon AI by GrandScore reads a photo of printed piano sheet music and turns it into a playable score. It runs in your browser, and you can try it once for free.
Is there an app that plays sheet music from a photo?
Upload an image of the score (PNG or JPEG) to Hanon AI and it becomes a playable score. Beyond playback, you can practice it with slow tempo, one-hand mode, partial playback, and a MIDI keyboard. It runs in the browser, so there is nothing to set up.
How do I turn a picture into sheet music I can play?
Upload the picture to Hanon AI. It reads the notes in the image and rebuilds them as a score, so what you get back is playable notation rather than a recording. A photo of a printed page, a screenshot, and an image exported from a PDF all work.
Is this sheet music OCR?
The equivalent of OCR for music is called OMR — Optical Music Recognition. Text OCR reads characters along a line; OMR has to read pitch from vertical position and duration from note shape at the same time, on staves crossed by slurs, beams, and dynamics. That is why it is a separate problem.
Is it free?
Once, yes. AI score creation is free once. After that it needs Premium, which includes up to 15 AI scores a month. A scan only counts once you register the result, so reviewing costs nothing.
Can I play sheet music from a PDF?
Yes, with one extra step. Uploads are images, so export the PDF page as a PNG or JPEG, or zoom it to fill the screen and take a screenshot, then upload that image. Images made from a PDF have no perspective distortion or shadows, so they usually read more reliably than photos.
The reading came out wrong. What should I fix?
Shoot straight down rather than at an angle, keep shadows off the page, fit the full width of the staves in frame, and flatten any curvature from the binding. Retaking is free — a scan only counts once you register the result.
Can it read handwritten scores?
No. Hanon AI currently works on printed piano sheet music. Handwritten scores and scores with three or more staves (ensemble, vocal) are not supported.
Are my uploaded scores made public?
No. Only you can see the scores you upload. GrandScore never distributes, sells, or publishes them.
