WebThe pitch material of a strict 12-tone work is entirely (or nearly entirely) derived from a single 12-tone row.A row is an ordered set of the twelve pitch classes of the chromatic scale. Each of the 12 will appear exactly once, and order is paramount. 12-tone rows that can be related to each other by transposition, inversion, and/or retrograde operations are considered to … Webthe pitch class interval ascending (clockwise) from the 1st to 2nd pitch class.

WebIn summary, pitch classes are groups of pitches related by octave and enharmonic equivalence. A♭ 4, A♭ 3, G♯ 2, etc. are all members of the same pitch class. Example 1. Pitch versus pitch class. Integer Notation Example 2. The twelve pitch classes represented as a … WebAlso see pitch interval, pitch-class interval, and interval class. interval class — unordered pitch-class interval (i.e., the smallest possible distance between two pitch classes). Only integers 0-6 are possible. A major second and a minor seventh are said to be members of the same interval class (ic 2). interval-class vector — an ordered ... flowers of alaska pictures

http://openmusictheory.github.io/normalOrder.html Webordered pitch interval – The number of semitones from one pitch (not pitch class) to the next. Ascending intervals are denoted by positive numbers, descending intervals by … The unordered pitch class interval i(a, b) may be defined as where i⟨a, b⟩ is an ordered pitch-class interval (Rahn 1980, 28). While notating unordered intervals with parentheses, as in the example directly above, is perhaps the standard, some theorists, including Robert Morris (1991), prefer to use braces, as in i{a, b}. Both notations are considered acceptable. green bin collection chichester
