Definition
A specialization of both SoundInformationBearingThing and Artifact_Intangible. Each instance of Music is a particular sound produced by actions such as singing, whistling, playing an instrument, playing recorded music, and so on. Music has certain features that distinguish it from random noise (though recognizing them may depend upon a specific cultural background); such features usually include variations of pitch over time (i.e., melody), multiple (somehow) related pitches sounding at one time (i.e., some kind of harmony), and/or some regular temporal pattern to the component sounds (i.e., rhythm). Instances of Music include the debut performance of Beethoven's Fifth Symphony, Leonard Bernstein's rendition of the Ninth Symphony with the BPO in Berlin in 1989, a particular playing of a particular CD of Bernstein's 1989 Ninth in Berlin, and the Messiah sing-in in Austin, TX, in 1995. This collection is not to be confused with MusicalText or MusicalTextCopy (qq.v.), which refer to the represented instructions which musicians often follow in order to create Music.
