Common mistakes

B♭7 has A♭ as its 7th — a half-step lower than B♭maj7 (which has A natural). Replacing A♭ with A produces B♭maj7 (a stable tonic chord). On guitar, B♭7 is most often a 1st-fret A-shape barre. The chord is fundamental to big-band jazz because of B♭'s role as the natural concert key for horns.

In context

B♭7 is the V7 of E♭ major (B♭7 → E♭maj7 — the cadence in every E♭-major jazz tune), the I7 of B♭ blues, and the IV7 of F blues. In ii–V–I in E♭ major, the progression runs Fm7 → B♭7 → E♭maj7. Charlie Parker's "Confirmation" (in F major) uses B♭7-related dominants throughout.
