Systematic reorderings of scale degrees and intervals
Permutations create new melodic patterns by reordering the notes or intervals of existing scales.

PERMUTATION THEORY
Permutations create new patterns by systematically reordering elements. In music, we can permute:
  • Intervals (creating modes from a scale)
  • Pitches (creating inversions of chords)
  • Sequences (twelve-tone row transformations)
  • Subsets (selecting and reordering scale degrees)
