Music Encoding Initiative

The Music Encoding Initiative (MEI) is a community-driven effort to define a system for encoding musical documents in a machine-readable structure. MEI brings together specialists from various music research communities, including technologists, librarians, historians, and theorists in a common effort to define best practices for representing a broad range of musical documents and structures. The results of these discussions are formalized in the MEI schema, a core set of rules for recording physical and intellectual characteristics of music notation documents expressed as an eXtensible Markup Language (XML) schema. It is complemented by the MEI Guidelines, which provide detailed explanations of the components of the MEI model and best practices suggestions.

MEI is hosted by the Akademie der Wissenschaften und der Literatur, Mainz.

If you want to become an active MEI member, you are invited to read more about the community and then join us on the MEI-L mailing list.

MEI is sponsored by the following Institutional Members:
