What is this?

The PDF viewer in the Chorilo app is more than just a display — it is your central tool for practicing and performing right on the score. While the web only offers a simple preview, the app provides every tool for active rehearsal work.

Tools in the viewer

  • Pen tool — draw directly on the PDF: breath marks, slurs, notes (see Draw PDF annotations)
  • Piano keyboard — overlay keyboard to sound single notes or chords
  • Metronome — keep tempo without switching apps
  • Audio player — start audio examples right in the PDF, with loop and tempo control
  • Jump marks — quickly jump between verses, chorus or bookmark points
  • Page rotation — landscape or portrait
  • Zoom — pinch-to-zoom for detail view
  • Multi-page navigation — swipe, tap the table of contents

How to use the viewer

  1. Open the Sheet music tab in the app
  2. Tap a piece
  3. Tap the PDF to display it
  4. The viewer opens full-screen
  5. Toolbar at the bottom or side (depending on device orientation) — pick the tool you want here

Tips

  • In concert keep the app in the foreground and enable concert mode (no auto-lock)
  • Tablet in landscape for two-page view — especially handy for long pieces
  • Save important pieces offline so you do not depend on Wi-Fi at the performance
  • Use jump marks for the concert order — faster transitions than flipping pages

Permission

Every member with sheet_music.view can use the viewer.

Frequently asked questions

Where do I find the PDF viewer in the web?▾
The web has a simple PDF preview (view + download). The advanced features (pen, piano, metronome, audio player, jump marks) are exclusive to the mobile app.
Does the viewer work offline?▾
Yes. If you have saved the piece offline (see Make PDF available offline), you can use the viewer and all tools without internet.
Are my annotations shared with other members?▾
No. Pen annotations are personal by default. Other members draw their own annotations independently — you do not see theirs.
