How does this relate to lyrics (texts), compositions (tunes/melodies) (which is what "composer" currently refers to), and arrangements? From what I understand of the above and from my musical experience, the above is an expression of an arrangement. Lyrics (poems, other texts) can exist for years before being associated with a composition (see [[Artist:fcd87005-5392-4d86-87f7-0fbf79105392|Sussie Nielsen]]'s [[Album:db6abd57-9cc0-4170-ad18-a8dc2676c4aa|Pigens morgen]] (not fully AR'd!), where most of the tunes were composed by Sussie, while all of the lyricists, except herself of course, were dead before she was even born (the youngest poet featured, apart from herself, died in the 1940's)!). However, what we get on the recording is not the lyrics or the tune as they are written, but instead as they are arranged. (This might also be related to the [[Trad Factor|TradFactor]], but I have to think more about it.) -- [[User:FrederikSOlesen|FrederikSOlesen]] 21:04, 19 April 2007 (UTC) ([[Answer Me|AnswerMe]], please.)

This page describes the composition object and its role in the ObjectModel.

Definition

A Composition is the object below the ../SongObject.

Actually a composition is an object of national law. A composition is considered a "work" of art and is copyrightable. We could use that definition. However they differ slightly from nation to nation. For now we can define a composition as something that can be put down on a score.

Boundaries

Boundary to the SongObject

A song becomes factual when the artists start composing and writing lyrics. This is more "touchable" than the mere idea of the song, as you can see the lyrics and notes. Therefore as soon as the song becomes an object of the real world (not the world of ideas[1]), it is a composition.

Boundary to the Recording Object

A composition exists in the mind of the composer or as notes as sheet music. As long as it is not audible, it is a composition. Every recording of the performed composition becomes a ../RecordingObject instance.

Relationships

Relationships to the SongObject

  • Attention.png Because the ../SongObject became obsolete, the relationships to song will not be implemented. A ../CompositionObject is based on exactly 1 ../SongObject.
    • Since the song is an abstract idea, we can say that a composition is based on exactly one song. There is an idea to every object of the real world[2].
      • Or should we allow a composition to be based on multiple songs? At this point the abstract idea of a song is becoming wobbly. We'd need some examples here.

Relationships to the ArtistObject

  • The artist(s) responsible for writing the music and/or lyrics of a ../CompositionObject are its composers. This relationship is optional (for cases where the composing artist is unknown or not available). This relationship defines the ../ArtistObjectRole Composer.
