They include both the direction and distance between the pitches, (-3, +16). + = ascending - = descending What is an unordered pitch interval? It includes the distance between two pitches but NOT the direction. Discuss ordered pitch class intervals.

A Guide To Music Intervals: The Gaps Between The Notes

http://www.jonathandimond.com/downloadables/Theory%20of%20Music-Basic%20Atonal%20Theory.pdf WebOrdered pitch intervals are associated with a very specific sound (e.g., +15); unordered pitch-class intervals (e.g., interval class 1) are less vivid or real. A basic concept in pitch-class set theory is that these levels of concreteness and abstractness encompass not only pitch and interval, but groups of pitch classes as well. simplicity s24 wand lock

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, … 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. WebAs the pitches are entered, the app will calculate normal order, prime form, Forte number, and the interval class vector. The pitch wheel will display the pitches using sharps or flats. When the pitches are entered, each one will sound to give the user an idea of how the pitch class set sounds. simplicity s24 filter
