The diatonic range is a size range of the fifth interval defined by the bounds 4\7 and 3\5.

Stacked (octave-reduced) fifths (R5) within this range build scales with distinguishable

  • "diatonic whole tones" (M2 := 2*R5 - P8),
  • "diatonic semitones" (m2 := 3*P8 - 5*R5), and
  • "chromatic semitones" (A1 := M2 - m2)

of a non-negative size. Some examples:
