From the file you download to the piece you perform

A viewer displays a file. OPUS Reader follows your scores through their whole life: you gather them, you file them, you work on them, and you find them again on stage as well as in the practice room.

1 Gather The Free-scores.com catalogue, files from your computer, scanned PDFs, photos of printed sheet music.
2 File Categories, sub-categories, tags and search: your filing system, not ours.
3 Practise Tempo, loops, annotations, fingerings, backing audio: everything stays attached to the file.
4 Perform Setlists, continuous playback, concert mode and hands-free page turning.
5 Take it with you Offline on your tablet, synced across your devices, backed up as a single archive.

A real file manager, built into the reader

Your scores are not a list of links: they are files you sort, rename, group and find again, whatever their format.

What you can do

Far more than a score shown on screen

Playback, practice, accompaniment, annotation, archiving: OPUS Reader gathers into a single page everything that usually takes several separate programs.

Hear the score and follow it

The engraving is redrawn on screen by Verovio and the cursor follows the music note by note. A4 page, horizontal scrolling or a continuous ribbon: pick the layout that suits you.

The score listens to you play

Plug in a MIDI piano or simply use the microphone: OPUS waits for the right note in sight-reading mode, or follows you without stopping in flow mode.

On-screen keyboard and falling notes

The keyboard shows the keys to play, the fingering and which hand is involved. Falling-note mode makes learning easier, with a keyboard scaled from 25 to 88 keys to match your instrument.

The tools of everyday practice

Slow the tempo down, loop a hard passage with a gradual speed-up, mute a part so you can play it yourself, transpose for your instrument, keep the metronome at hand.

Frequently asked

Before you start

Is it free?

Yes. Playback, practice mode, loops, transposition, annotations, setlists, MP3 and YouTube play-along, the games: all of it is free, with no limit on the number of scores. Only a few advanced features need a Premium account:

  • exporting a score as a PDF
  • syncing your library to our servers beyond 3 files: you can keep as many as you like on your account, they are simply not synced
  • audio recordings beyond the first 3
  • video export on a transparent background, meant for editing suites: the other video exports stay free
  • converting a PDF into an XML score
  • in the PDF reader, looping and slowing down on a PDF synced to audio
Do I need to install anything?

No. OPUS Reader runs in the browser, on computers as well as tablets and phones. You can still add it to your home screen to use it like an app, including with no connection.

Which files can I open?

Scores engraved in MusicXML, MXL and MEI, PDF files, ChordPro charts and MIDI files. You can open a score from the Free-scores.com catalogue or drop in your own files.

Do I need a MIDI keyboard?

No, but it helps. With no hardware at all, the microphone is enough for the reader to follow your playing. With a MIDI piano, wired or Bluetooth, tracking gets more precise and the fingering appears on the on-screen keyboard.

Are my files uploaded to a server?

A score you open from your own device stays in your browser. Saving to our servers, useful to find your library again elsewhere, only happens if you ask for it.
