2         Simple Operations on Pitch Classes and Pitch Class Sets

2.1          "Clock" Math or Modulo Math

 

 

o        A tritone is made up of two notes which are
opposite of each other (for example:  C = 0 and F = 6)

o        The notes of a cross make up a doubly-diminished 7th
chord (for example:  C = 0, D = 3, F = 6, A = 9)

o        The augmented triad (C = 0, E = 4, G = 8) is also
pleasingly symmetric.

2.2          Transposing Pitch Class Sets

2.3          Inverting Pitch Class Sets
