Become a sponsor to Open Sheet Music Display

πŸ‘‹ Become a sponsor and get the OSMD Audio Player πŸ‘‹

OpenSheetMusicDisplay is a free, open source library for displaying MusicXML sheet music in the browser. But we have also been working on an audio player for years, which used to be proprietary.

Now you can get early access to the OSMD Audio player by becoming a monthly sponsor of OSMD (Enthusiast tier or higher). Eventually, this player will become open source as well, when we have reached our sponsor goals. But already, many of our sponsors are using the player to create music apps, and just like OSMD, it is constantly being improved.

You can read more about the OSMD Audio Player here:

🌟 Our mission 🌟

Our mission is to provide a state of art software solution for building (sheet) music apps and to include the community in our constant thrive for improvement. We want to take away the pain of building the software from scratch and offer a shortcut when it comes to building your next MusicXML app. In order to lower the entry barrier of developing sheet music apps even more OSMD is provided for free, forever.

πŸ™ Why do we need your support? πŸ™

Sadly, "free" isn’t sustainable on its own. 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 to enable us to continue our work, improve and bugfix Open Sheet Music Display.

These new features are currently in the making:

  • Audio Player (based on jimmy's player, but continuously improved)
  • Transposing (now public in OSMD 1.0.0 thanks to sponsor support!)
  • Annotations
  • Further MusicXML capabilities like pedal signs and trill lines (wavy-line)

However, coding isn’t the only way to contribute to the community - we plan on starting a blog & a newsletter and share our knowledge. We encourage our sponsors to bring up their desired features and pitch blog post ideas.

πŸ™Œ How can you help? πŸ™Œ

Any help of getting the word out is very much appreciated, feel free to share the news with other music tech or open source enthusiasts. If you have any questions or would like to share your opinions and suggestions on further development of our products write to us at or add an issue in our repository.
