Minor scale
The three common minor scales built on C.
A minor scale is a sequence of musical notes in which the third scale degree is a minor third above the tonic. The notes A–B–C–D–E–F–G form a prototypical minor scale.
There are three common types of minor scales: the natural minor scale, the melodic minor scale, and the harmonic minor scale. The Aeolian, Phrygian, and Dorian modes are also examples of minor scales.
