Verovio is a fast, portable and lightweight library for engraving Music Encoding Initiative (MEI) digital scores into SVG images. Verovio also contains on-the-fly converters to render Plaine & Easie Code, Humdrum, Musedata, MusicXML, EsAC, and ABC digital scores.
Verovio is written in standard C++20 and is available in several bindings (JavaScript, Python, Java, Swift, Go). It can be compiled as a standalone command-line tool or as a music-rendering library for applications. Check out the JavaScript toolkit version of Verovio running in the Verovio Online Editor / Viewer, or the tutorials to know more about web integration and user interaction.
