Neon2: Neume Editor Online

Neon2 is a browser-based music notation editor written in JavaScript, designed for working with square notation. It uses Verovio to dynamically render the symbolic music files in MEI format, updating the file in real time through a graphical interface. Neon2 can be used for creating new musical scores, making ground-truth data for machine learning, or for correcting errors from automated transcriptions in an OMR workflow. Neon2 is designed as part of an optical music recognition workflow, allowing for quick and easy correction of pitch and position errors created in the OMR process. Every component of our OMR process is designed as an accessible online application, to allow correction tasks to be crowdsourced from our partner organizations and community members.

Demo

You can try out Neon2 on our demo page. You can begin by selecting a link to a musical document that has undergone OMR, and then continue to insert, delete, or pitch shift notes on the page.
