Blues scale

The term blues scale refers to several different scales with differing numbers of pitches and related characteristics. A blues scale is often formed by the addition of an out-of-key "blue note" to an existing scale, notably the flat fifth addition to the minor pentatonic scale. However, the heptatonic blues scale can be considered a major scale with altered intervals.

Types[edit]

Hexatonic[edit]

The hexatonic, or six-note, blues scale consists of the minor pentatonic scale plus the 5th degree of the original heptatonic scale.[1][2][3] This added note can be spelled as either a 5 or a 4.
