About OSMD

<img title="How OSMD can look in the browser&#xA;(Mockup, OSMD on its own does not support playback)" src="https://user-images.githubusercontent.com/33069673/106186552-bd191300-61a4-11eb-8814-07019fcf1d5b.png" style="max-width: 100%; max-height: 100vh; width: auto; margin: auto;">

OpenSheetMusicDisplay renders MusicXML sheet music in the browser. It is the missing link between MusicXML and VexFlow. Built upon many years of experience in both sheet music interactivity and engraving, it is the perfect solution for app developers seeking to build digital sheet music services.

MusicXML is the de facto standard for exchanging sheet music between music software.<br> VexFlow is widely used for rendering sheet music. It features an extensive library of musical elements, but each measure and symbol has to be created and positioned by hand in Javascript.

OpenSheetMusicDisplay brings the two together and offers an open source turnkey solution for your digital sheet music project.

Demo

Try the Public Demo to see what OSMD can do.<br> Learn more about the demo and OSMD in the OSMD Wiki.

Developers can also run a local development demo (see Wiki):

<img title="Local OSMD Development/Debug demo" alt="Local OSMD Developer Demo" src="https://user-images.githubusercontent.com/33069673/106189263-5695f400-61a8-11eb-901f-aafc853af497.png" style="max-width: 100%; max-height: 100vh; width: auto; margin: auto;">

Key Features

• Displays MusicXML sheet music in a browser(less) environment (Javascript, Typescript, server-side: browserless NodeJS script)
• Soon: Audio Playback (work in progress, early access build available for Github sponsors)
• Uses Vexflow for rendering and (partly) layout
• Parses most MusicXML tags and integrates it into an accessible and modifiable data model (e.g. to change a note's color)
• Offers many options (OSMDOptions / EngravingRules): Page Format, Font Family, Positioning, not rendering certain elements like the title or lyrics, etc.
• Allows modification of the displayed score, like hiding parts or instruments, hiding instrument names, title or composer, a more compact layout, or coloring notes
• Outputs SVG or PNG, also via nodejs script in the command line, completely browserless (e.g. for server-side rendering)
• Written in Typescript with complete type information, 100% compatible with Javascript (minified build is .js)
• Can display tablature (guitar tabs) from MusicXML, including effects like bends and glissandi. Can be combined with treble clef. <img src="https://user-images.githubusercontent.com/33069673/127324371-b7c5f137-a1b8-4127-95b0-38e6a185c906.png" height="130">

Limitations

Not all MusicXML tags are (fully) supported:

• Pedal marks (currently in early access for sponsors)
• Glissando lines
• Wavy-line (currently in early access for sponsors)
• Etc, see OSMD 1.0 Project

Also, OSMD is a renderer, not an interactive sheet music editor. Rendering takes some time, and you can't easily/quickly move notes, place new notes, etc.<br> (You can, however, manipulate the SVG nodes for instant changes like note re-coloring, see Exploring the Demo | Wiki)

How to Use OSMD

• Available as NPM module, can be used with plain javascript or module managers like webpack
• Getting Started: Detailed instructions in our Wiki
• If you have further technical questions, you can:
  • Leave a comment in our Discussions section (especially for questions of understanding)
  • Browse through our Issues
  • Open a new issue (may be moved to Discussions).

Sponsor OSMD and get early access to the audio player and more

<a href="https://github.com/sponsors/opensheetmusicdisplay/" alt="OSMD on Github Sponsors"> <!--img src="https://user-images.githubusercontent.com/33069673/104042293-99ccfa80-51da-11eb-9dc9-fac075a33224.png" height="200" alt="OSMD on Github Sponsors"--><img src="https://user-images.githubusercontent.com/33069673/109203612-a9150100-77a4-11eb-9b91-6692850dccab.png" style="max-width: 100%; max-height: 100vh; width: auto; margin: auto;"> </a><br>

It would be great if free software were sustainable on its own. But to keep on improving and developing OpenSheetMusicDisplay we need your support. Your monthly sponsorship subscription - especially if you are already actively using OSMD - would mean everything to us - it’s a stable way of enabling us to continue our work, and improve and expand OSMD.<br> Features already available in early access:

• OSMD Audio Player
• Native modules + example projects (React Native, Kotlin/Android, Swift/iOS) - NEW!
• Jianpu Display (Numbered Musical Notation), with playback

Features in the making, potentially available in future:

• Annotations (Add custom text, music symbols, etc. to the score and export to and import from XML)
• and more (we're always working on OSMD improvements or additional features, just look at our release history / changelog!)

Besides the early access features, you can get other perks like a personal postcard from the team in Vienna. Check them out at our GitHub sponsors page.
