Neon.js: Neume Editor Online

Neon.js is a browser-based music notation editor written in JavaScript. The editor can be used to manipulate digitally encoded early musical scores in square-note notation. Neon.js will serve as a component within an online optical music recognition framework. The primary purpose of the editor is to provide a readily accessible interface to easily correct note pitch and position errors made in the process of optical music recognition. By making the editor easily accessible online, the task of correcting OMR errors can be distributed amongst many people to accelerate the creation of ground-truth data and errorless symbolic music collections. Neon.js can be used to create new musical scores, or to correct errors from automated transcriptions in an optical music recognition (OMR) workflow.

Demo

You can try out Neon.js 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.
