A Tweleve-tone Row is a special form of Pitch Class Sequence, where each pitch-class is used exactly once. All objects of this form have exactly twelve elements. A large body of 20-century music is based wholly, or in part, on twelve-tome rows. There is also a large body of theoretical writing on this subject. The Twelve-tone Row can be subject to transposition, inversion, multiplication, and operations on order, such as retrograde, rotation and permutation.
I've tried to make the syntax for interacting and creating object as simple and intuitive as possible. Here are some general guidelines.
Pitch class notation should be entered using the integers 0-9 and the letters 'a', 'A', 't', or 'T' for 10, and 'b', 'B', 'e', or 'E' for 11. Upper and lower case may be mixed. As these tokens are uniquely distinguishable, there is no need for spaces or other separators, such as spaces or commas, and anything other than the allowed tokens are ignored.
Pitch Set notation should be entered using the integers 0-128, or using a notation language specifying the note-name and register. The note-name notation follows a simple mini-language:
