Sheet Music Scan

Turn sheet music into a click track

Skip the manual setup and go straight to practicing. Scan your sheet music—camera, photos, or a PDF—and Subdivide reads the tempos, time signatures, and bar counts, then builds a click track that follows the piece from the first bar to the last.

How it works

How a scan becomes a click track

  1. The Review pages screen showing two scanned pages, with buttons to add more from the camera, Photos or Files

    Step 1

    Scan your pages

    Use the camera, pick photos, or open a PDF from Files—up to 12 pages per scan. Add, remove, or reorder pages before Subdivide builds the track.

  2. A click track built from scanned sheet music: section A at 168 BPM in 4/4, section B at 114 BPM in 7/8, and section C ramping from 114 to 180 BPM

    Step 2

    Subdivide reads the music

    Every tempo change, meter change, and repeat becomes a section of your track. An accelerando turns into a ramp across the bars it covers.

  3. The track player during a tempo ramp from 114 to 180 BPM, with the next section shown underneath

    Step 3

    Review and play

    Give the sections a once-over against your music, then save. Everything stays editable, same as a track you built by hand.

What it reads

What Subdivide reads from your sheet music

  • Tempo markings

    The BPM and which note gets the beat.

  • Time signatures

    Every meter change, including cut time.

  • Bar counts

    Multi-measure rests included.

  • Repeats and pickups

    Repeat signs and pickup bars.

  • Accelerandos and ritardandos

    And how many bars they stretch over.

  • The title

    Your track is named after the piece.

After the scan

Work the tough passages

Once it's built, a scanned click track works like any other track in Subdivide.

  • Start slow, work your way up. Slow the whole track down without rewriting your tempo map. Build confidence, then bring it up to speed.
  • Loop and count off. Loop any section, count off into it, and run as many reps as you need.
  • Share it with the ensemble. Send a link or put the QR code on a screen. Everyone rehearses with the same tempos and transitions—and anyone can play it, iPhone or not.
  • Export the audio. Save your track as an audio file to share with students, bandmates, and friends.

Building a track by hand instead? How to practice music with tempo changes walks through it. Marching ensembles can also lay drill pages and counts over a scanned track.

Already have the score as MusicXML?

Skip the camera. Export MusicXML from MuseScore, Sibelius, Dorico, or Finale and drop it into Subdivide, which reads it the same way it reads a scan. It takes .musicxml, .xml, and compressed .mxl files, and combines several files into one track when each movement is its own file.

What happens to your pages

Subdivide uses AI to read your pages. They go to our server, which passes them to OpenAI. We delete them the moment the scan finishes; OpenAI keeps them for up to 30 days, then deletes them.

Your pages are only ever used to build your track—never to train AI models. We ask for your agreement before your first scan, and the privacy policy has the details.
