your sheet music,
now with a play button.

You photograph a page of printed sheet music with your phone. Sheetly reads the notation: pitches, rhythms, clefs, key and time signatures. Then it hands back a score you can press play on. From there you can loop a bar, slow the tempo, switch instruments, record yourself, and ask a coach about the piece.

It depends almost entirely on the photograph. A flat, straight-on, evenly-lit page of printed notation reads very well. On our own 31-piece benchmark Sheetly scored 96% on clean scores and 95% on photographed ones, against Audiveris 5.11.0 at 88% and 50%. Scoring is strict F1: a note only counts when pitch, onset and duration are all correct. Angled shots, shadows, page curl and tightly-bound books are what cause mistakes. Here is how to photograph a page so it reads cleanly.

Piano and other grand-staff music, single-line instrumental parts for strings, winds and brass, and vocal lines. It handles treble, bass and the other common clefs. It reads printed and engraved notation rather than handwritten manuscript, and it is not a guitar-tab reader.

Yes. Once a page is scanned, the coach has the notes of that score, so you can ask about bar 3 or bar 12 by number: which fingering or slide position, why the rhythm keeps collapsing, what a marking means, which bars to drill. It answers about your page, not generic advice. It does not listen to you play. What you can ask, with examples.

Yes. You can set any tempo, loop a single difficult bar or a passage, and walk the speed back up as it gets easier. You can also record your own take and play it against the score to hear where you drifted.

Free to download, and the scores it comes with are free to view, play, loop, slow down and record against. You can scan your own sheet music for free too: your first pages while you set up, then one page a month, and every score comes with three questions for the coach. Pro removes those limits and adds PDF import and export to PDF, MIDI and MusicXML: US$11.99 a month or US$39.99 a year, and the yearly plan starts with a 14-day free trial. Apple charges the equivalent local price elsewhere. No lifetime tier, no ads.

Scores you have already scanned live in your library and play back on the device. Scanning a new page and asking the coach a question both need a connection, because the recognition and the coaching run on our servers.

Not yet. Sheetly is on iPhone and iPad today, and an Android version is in development.

Your scores live in your own account. They are never sold or shared, there are no ads and no third-party trackers, and you can export or delete everything at any time. The full privacy policy is here.
