Verovio is a fast, portable and lightweight library for engraving Music Encoding Initiative (MEI) music scores into SVG. Verovio can be used as a standalone command-line tool for converting a MEI files, as the music rendering library for applications, or it can be compiled to Javascript using the Emscripten LLVM-to-JavaScript compiler.

See the JavaScript toolkit running in the MEI Viewer and check out the app or the tutorial for its web integration and for enabling user interaction.

Choice interaction

Verovio can also render Plaine & Easie Code and imports MusicXML, Humdrum data, and ABC notation. It is designed as a tool usable as a one-step conversion tool and it is written in pure standard C++.

Verovio follows the Standard Music Font Layout (SMuFL) specification and the font can be changed for personalizing the output.
