What makes B♭ Blues different
The blues scale is the minor pentatonic with one extra note, the ♭5, which gives it six notes. The added note sits between the fourth and the fifth, making 4, ♭5, 5 the only chromatic run in the scale. It's a passing note: players rarely hold it, and bending or sliding through it is what gives blues phrasing its cry. Over a blues in a major key, the scale's ♭3 also rubs against the major third of the chords, the second source of that tension. On B♭, B♭ Blues is B♭ Minor Pentatonic (B♭ D♭ E♭ F A♭) with F♭ added.
How to use the B♭ Blues scale
Because B♭ Blues has fewer or more than seven notes, it doesn't produce a standard set of seven diatonic triads. Instead, build chords by stacking thirds within the scale or use it as a melodic colour over chords drawn from a related diatonic key.
The blues scale is where blues, rock, R&B and jazz improvisation live. That added flat fifth with all the bends and slides - that's its signature voice.
