Blues scale

Uncommon card · No. 191666

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 or the addition of the minor third to a major pentatonic scale. However, the heptatonic blues scale can be considered a major scale with altered intervals.
