12/26/2023 0 Comments E flat dominant 7th chord![]() Let's say we want to transpose our H 1 up by six half-steps, T 6. Note that in mod6, 7 becomes 5, 8 becomes 4, and so on.īack to our example (C, C#, D, Eb, E, and F ). Go beyond a tritone (6) because anything from 7 through 11 can be inverted to an interval from 1 through 6. 1 is a half-step, 2 is a whole step, and so on all the way through 6, a tritone (six half-steps). Here, " n" is a variable for an interval to be represented by a whole number from one through six. ![]() Reversing the order of H 1 and inverting it (retrograde-inversion): R(I n).Reversing the order of H 1 (retrograde): R n.This group of pitches by applying one of the traditional transformations to the group as a whole. "H" stands for hexachord and " 1" represents group 1. Treat these six pitchesĪs a group named H 1. Let's assume that we have six different pitch classes: C, C#, D, Eb, E, and F (the first six notes of a C chromatic scale). The resulting six pitch classes are referred to as a complement. With a transformation of itself under 1) prime (transposition, T n)Ģ) retrograde, R(T n), 3) inversion, I n orĬreates an aggregate, or a collection of all 12 pitch classes. A hexachordally all-combinatorial set is a collection of six pitch classes that when combined
