Diatonic Scale - Analysis

Analysis

In music of the broadly western classical tradition the pattern of seven intervals separating the eight notes of an octave (see heptatonic scale) can be represented in three ways, which are equivalent to each other. For instance, for a major scale these intervals are:

• T-T-S-T-T-T-S: where S means semitone; T means tone
• 2–2–1–2–2–2–1: where 1 means semitone; 2 means tone (2 semitones)
• whole-whole-half-whole-whole-whole-half: where half means semitone (half a tone); whole means tone.
