Thus, a C-major collection means a collection of pitches in the major mode, arrayed around the pitch C. The four pitch-class sets circled in Example 11 are all transpositions of one another. Pitch-class inversion occurs when all pitch classes of a collection are inverted, or flipped, around an axis of symmetry in pitch-class space (in other words, the axis of symmetry is a pitch class). A chromatic scale is one in which all of the pitch classes are played. 24, second A dual interval space (or "DIS") is a two-dimensional array of pitch classes, in which each dimension corresponds to a unique (non-zero) interval class.

But where a "pitch class" is a collection of pitches that are all in a sense "the same", a "pitch class set" is a collection of several different pitch classes, and the differences between them will be important. An octatonic collection is easily generated by alternating half steps and whole steps. major scale. If we were to select all twelve of the pitch classes we would have a chromatic collection. Previous musicians have created two ideas to help us learn keys quickly: scales and key signatures. In 12-TET, there are twelve pitch classes, conventionally named with numbers starting from zero. Some theorists prefer to find normal order using the pitch class numbers 0-11 arranged in a clockface: Unbreakable Ties for Normal Order and Best Normal Order 1. PITCH CLASS. 2. The technique for determining the equivalence class of a pc set (without the use of the Set Analyzer) is to follow the technique given below, and then look up the result in the table.

Pitch-class sets can be categorised: there is a bounded collection of sets withN =3,4,5 or 6 pitches (the complement of that collection is formed by sets with N =7,8 or 9 pitches). If notes are enharmonically equivalent, then the system of seven letter names does not work well to describe the twelve pitch classes. This is a list of set classes, by Forte number. with each pitch from the full collection occurring only once. Collections and Scales. Write as a collection of pitch classes (eliminating duplicates) in ascending order and within a single octave. For example, G7 is a pitch-class set, G–B–D–F, and so is the C-major scale, except C in this context has two locations in pitch space (the beginning and end of the scale) and one in pitch-class space. pub A pitch-class set or pitch-class collection is a group of pitch classes. For example, the 12 major triads are all related by transposition. Sets are listed with links to their complements. scale.
