KINDS OF SCALE – DIATONIC (MAJOR AND MINOR) CHROMATIC AND PENTATONIC
Diatonic Scale
A diatonic scale consists of seven notes and the eighth note is the repetition of the first note .i.e. doh, re, mi, fah, soh, lah, te, doh. Semitones occurred between the third & fourth note of the scale (mi & fah) and between the seventh note and the eighth note of the scale (te & doh) while others are whole tones. Hence, the formula is T, T, ST, T, T, T, ST. Where T = Tone and ST = Semitone.
There are two types of diatonic scale namely: Diatonic major and diatonic minor scales. The diatonic major scale is the common doh, re, mi, fah, soh, lah, te, doh.
The diatonic minor scale also consists of eight notes but the first note is from the sixth note of the scale submediant. i.e. (lah).
Minor Scales
There are three types of minor scales:
- Natural minor
- Harmonic minor
- Melodic minor
Natural minor is exactly as the key signature dictates.
