Verovio

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.

September 09, 2025 – Version 5.6 released

The changes introduced in release 5.6 are mostly small fixes and improvements, particularly in the timemap and MIDI output, and some data importers.

One notable enhancement is the improved layout of editorial (cautionary) accidentals. This new approach allows for more refined positioning, especially when they appear close to slurs. We may extend this method to other elements in the future.

Another addition in version 5.6 is a Python wheel for Ubuntu arm64. This makes it possible to use Verovio on that platform without requiring a lengthy build process.

August 04, 2025 – Version 5.5 released

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 SVG output of Verovio is designed as an intermediate reflowable layer that facilitates the development of interactive applications, such as music notation editors or interactive digital editions.

Verovio is designed to be usable in a wide range of technical environments (C++, JavaScript, Python).

It works on desktop computers but also tablets and mobile devices. Verovio also provides basic support for other music notation format, such as MusicXML import and MIDI output.

Why Verovio?

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.
