Bb — Major

B♭ · D · F

The Bb chord is built from the root, a major third, and a perfect fifth — B♭, D, F. Bright and stable — the first chord most pianists learn and the anchor of countless songs.

Bbm — Minor

B♭ · D♭ · F

The Bbm chord is built from the root, a minor third, and a perfect fifth — B♭, D♭, F. Darker and more wistful than major, and just as common across every style.

Bbaug — Augmented

B♭ · D · F♯

The Bbaug chord is built from the root, a major third, and a raised fifth — B♭, D, F♯. Restless and dreamlike; often a stepping-stone between two ordinary chords.

Bb7 — Dominant seventh

B♭ · D · F · A♭

The Bb7 chord is built from a major triad plus a minor seventh — B♭, D, F, A♭. Bluesy and unresolved; the workhorse of blues, gospel and jazz turnarounds.

Bbm7 — Minor seventh

B♭ · D♭ · F · A♭

The Bbm7 chord is built from a minor triad plus a minor seventh — B♭, D♭, F, A♭. Mellow and smooth — the backbone of soul, R&B and jazz comping.

Bbm7b5 — Half-diminished (m7♭5)

B♭ · D♭ · F♭ · A♭

The Bbm7b5 chord is built from a diminished triad plus a minor seventh — B♭, D♭, F♭, A♭. Also called half-diminished; most often the "ii" chord that opens a minor ii–V–i.

Bbdim7 — Diminished seventh

B♭ · D♭ · F♭ · A♭♭

The Bbdim7 chord is built from four notes stacked in minor thirds — B♭, D♭, F♭, A♭♭. Maximally tense and perfectly symmetrical — a favourite for passing and leading between chords.
