Designed for the Music Encoding Initiative - Fast - Light - Flexible - No dependencies
Verovio is a fast, portable and lightweight open-source library for engraving Music Encoding Initiative (MEI) music scores into SVG.
Verovio follows the Standard Music Font Layout specification, which makes it easy to change the music font for personalizing the appearance.

The 5.5 release brings a new binding to Swift, which is distributed via the Swift Package Manager. This makes Verovio very easy to include and use in iOS applications. See the Reference book documentation for details on how to use the Swift binding.
Another new feature of 5.5 is the option to use the Liberation text font, which can be embedded or linked to in the SVG. This improves the rendering of text on platforms where Times or Times New Roman is not available by default, such as Android.
The 5.4 release includes several small improvements and fixes. The time map and MIDI output have been corrected for measure rests, particularly in the case of upbeat measures. Another update involves changes to the key names in the JSON output when retrieving time information for certain elements in the time map.
A notable change is the reduction of the initial memory allocation in the JavaScript toolkit. This significantly lowers Verovio’s memory usage in most cases, which will be especially beneficial on less powerful devices. It should not affect the loading of large files — the original reason for the higher memory allocation — but that level of allocation is no longer necessary. As a result, the verovio-toolkit-light version, which offered a lower memory footprint, is no longer provided.
Verovio is developed by the RISM Digital Center with the support of the Swiss National Science Foundation. The project receives dedicated financial support from the Digital Mozart Edition, a joint project of the Salzburg Mozarteum Foundation and the Packard Humanities Institute, Los Altos/CA. It also received in-kind support from the Saxon Academy of Sciences in Leipzig from 2017 to 2019.
The source code is available on GitHub under the LGPLv3 license.

Do you use Verovio? Let us know!
Verovio is named after a Dutch music engraver, Simone Verovio, who was active in Rome in the late sixteenth century. He was one of the very first to use engraving on copper plates for printing music, a technique that was revealed to be the most suited to music about one century later.
