Classical Music Index (CMI) is a database of classical music information.

• It has complex and detailed information: movements, arrangements, instrumentations, creator roles, concerts, and so on.
• It allows complex queries: for example, you can find string quartets by composed by French women, or piano music by North Africans.
• It is editable: you can add entries about your compositions, your recordings, or yourself. Volunteer editors can fix or add details.
• It supports music discovery. You can rate things, and you can find music you'll like based on other people's ratings.
• It links to scores and recordings on IMSLP.

CMI is a non-profit project, created and operated by volunteers. Its source code is open source and is available on Github.

CMI is under development. The database may be reset at any time, in which case your account and items you've added will be lost. Please contact us if this is a problem.

Features based on ratings are simulated until we get enough ratings.

Check out CMI's companion project, Music Match, which helps performers and composers discover each other.
