A Scales for Blues Bass

24 types on one root. The minor pentatonic and the blues scale come first for most players; every other one is here too.

Every scale type this site maps, rooted on A and laid onto this seat. The two a blues player reaches for first are the minor pentatonic and the blues scale, which is the same five notes with one more squeezed in between the fourth and the fifth.

On the bass a scale supplies the notes between one chord and the next — the steps a line takes on its way to the change — far more often than it is played as a run.
