Tonal function in harmonic scales
Andrew J. Milne · 2005
Strict harmonic notation is assumed, so the intervals that make up a major or minor triad are p5/p4, M3/m6 and m3/M6; M2/m7 is taken to represent the difference between p5 and p4, as well as the difference between p4/p5 and m3/M6; 1 m2/M7 is taken to represent the difference between p4/p5 and M3/m6. All other intervals are taken to be augmented or diminished. An interval is assumed to include all octave expansions unless explicitly stated otherwise; so ‘U’ includes octave and double octave, ‘p5’ includes perfect 12 th and perfect 19 th
