Bbm7 Guitar Chord
Bb Minor 7th · also written A#m7 · Bb–Db–F–Ab
Bbm7 is the Bb minor 7th chord: Bb–Db–F–Ab. Its sound is mellow and soulful — softer than a plain minor chord, at home in funk, R&B, and jazz ii–V–I progressions. It's also written as A#m7 — same notes, same shapes, different spelling.
Bbm7 softens the Bb minor triad with a ♭7 (Ab). It's the standard ii chord in Ab major — the first chord of the ii–V–I, jazz's most important progression — and a staple of funk vamps and R&B ballads.
The most common way to play Bbm7 is the em7 shape at the 6th fret (6 8 6 6 6 6, low E string to high E string). Below you'll find 6 ways to play it across the neck, from open position to barre and shell voicings, with the theory behind the chord and the progressions it lives in.
