Bb: 24 Scales at the Upright Bass Seat

One root, every type. Pick the one that fits the chord you are on.

Every scale type this site maps, rooted on Bb and laid out at this seat. The modes of the major scale do most of the work over most of the repertoire; the rest are here for the bar where a dominant refuses to behave.

The upright takes a chorus less often than anyone, and that is exactly why these matter: the notes between one chord root and the next come out of a scale, and a walk that lands on the wrong one is the loudest wrong note in the room.
