| | Set theory (music) - Wikipedia, the free encyclopedia |
 | | Musical set theory deals with collections of pitches and pitch classes, which may be ordered or unordered, and which can be related by musical operations such as transposition, inversion, and complementation. |
 | | Although musical set theory is often thought to involve the application of mathematical set theory to music, there are numerous differences between the methods and terminology of the two, and between typical mathematical terminology and the terms used in musical set theory more generally. |
 | | Musical set theory is therefore best regarded as a field that is unrelated to mathematical set theory, and is instead an application of combinatorics to music theory but with its own vocabulary, whose main connection to mathematical set theory is the use of the vocabulary of set theory to talk about finite sets. |
