In MusicBrainz terminology, a work is a distinct intellectual or artistic creation, which can be expressed in the form of one or more audio recordings.
A work’s distinctiveness is based-on the artists that contributed to its final output. For example, a song that is the result of a collaboration between composer and lyricist would result in a single work, while an instrumental work with lyrics added later would be considered two distinct works. Translation of an existing work to a different language would also result in its own distinct work.
A remix or mashup of one or more works constitutes a new distinct work.
While a work in MusicBrainz is usually musical in nature, it is not necessarily so. For example, a work could be a novel, play, poem or essay, later recorded as an oratory or audiobook.
Types of works
Works are represented predominantly at two levels:
An individual song, musical number, movement. In many cases, discrete works are a part of larger, aggregate works.
An ordered sequence of one or more songs, numbers of movements, such as: symphony, opera, theatre work, concerto, and concept album (this is not meant to be an exhaustive list).
A popular music album is not considered a distinct aggregate work unless it is evident that such an album was written to have a specifically-ordered sequence of songs (e.g. a “concept album”).
A work has the following attributes:
The canonical title of the work, expressed in the language it was originally written.
A comment that can disambiguate the work from others with the same name by the same artist(s).
The international Standard Musical Work Code assigned to the work by copyright collecting agencies.
The type of work.
If a discrete work is known by name(s) or in language(s) other than its canonical name, these are specified in the work’s aliases.
A work is associated with artists, recordings and other works through advanced relationships.
A work can be associated with one or more composer, arranger, instrumentator, orchestrator, lyricist, librettist, translator and publisher.
A work can be associated with one or more recordings. This provides the indirect association between a work and its performance and production artists.
A work can be associated with one or more other works. There are two types of work-work relationships:
A work can be expressed as a part of another work.
Derivative work relationship
A work can be expressed as being derived from one or more other works. Examples: instrumental work with lyrics added later, translation of a work into a different language, remix, mashup.
- For remixes/mashups, what kind (composition!) ARs would be used to distinguish the derivative work from the original(s)?
- Part-of-relationship would ideally have an ordinal number to specify where in a sequence the discrete work would occur within its aggregate. Possible?
