MusoRepo: a Directory of Resources for Computational Musicology

This is a list of links to resources for computational musicology, with a focus on working with symbolic scores. It is limited to resources that are free and open source / open access. A few widely-used resources with restrictions (permission required, download limits, a commercial host, a paid book with free companion site) are included where useful, and are clearly marked borderline, with the restriction stated. Commercial software and consumer music services are deliberately left out; see the lists under Other lists below for those.

Pages:

Datasets (including scores) – on this page
Formats – list of standards, open-source notation, OMR. And for a very detailed report on divergence among the major standards, click here.
Software – parsing and analysis, visualisation, digital editions
Metadata and linked data
Teaching
Venues – journals, conferences and trade fairs

Not covered: research groups, which are maintained on the ISMIR website (see below).

Other lists

There are other excellent lists, including several for more specific tasks. I have contributed (or will contribute) this content to those lists where appropriate, but this one is distinct in its focus on working with scores. Please do reach out to contribute an item, to suggest how to organise this better, or to propose how we list-makers could coordinate our efforts.
