— About this chord

B13 (1–3–5–♭7–9–13) stacks the dominant seventh with rich upper extensions, delivering a lush, jazzy shimmer that still resolves like a dominant chord. A jazz and blues staple for turnarounds and closing vamps, it also colors funk and soul horn-style comping. On guitar it's a compact voicing built from the open B string; pianists love its wide, glossy spread. Functions as V13 resolving to I, adding sophistication without losing forward pull.
