Ordered pitch class interval
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. WebJul 1, 2024 · Ordered pitch intervals are as specific as possible: they measure specific pitches (in specific octaves) and represent the directionality of the interval. Interval …

WebJul 1, 2024 · A pitch-class set (pc set) is a group of pitch classes. The standard way of naming a pitch class set is by its normal order: the smallest possible arrangement of pitch …
Webordered pitch-class intervals is also a prime form. Since P can be transposed to any pitch-class level, we distinguish them with subscripts. There are multiple common systems for deciding the numbering. The simplest, which we will follow in this book, is to number the row by its starting pitch class. 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 negative numbers. Examples: B4–G5 would have an ordered pitch interval of 8 (eight ascending semitones). B3–G5 would be 20. B4–G4 would be –4.
Webof a row means looking at segments starting at each pitch in turn. For instance, for dyads (two pitches, one interval), we look at pitches 1 and 2, then 2 and 3, followed by 3 and 4, and so on. By considering two pitches at a time and stepping forward by one, there’s always one pitch overlapping. 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 …
WebTo put a set in normal order, order it as an ascending scale in pitch-class space that spans less than an octave. Then permute it cyclically until its first and last notes are as close together as possible. In the case of ties, minimize the …
WebThe ordered pitch-class interval is also the modulo12 version of the ordered pitch interval. For example, B4–G4 is –4 semitones (4 semitones down). mod12(–4) = 8. C3–D4 is 14 semitones. mod12(14) = 2. pitch – A pitch class in a specific register, such as C4 (middle C). reach for significanceWebPut the notes of a pitch-class set from a piece of music in ascending numeric order (like a scale).

It is thus more specific than the unordered pitch interval in that it represents the directionality of the interval. An ordered pitch interval always includes a plus or minus sign.
