Bbmaj7 Guitar Chord
Bb Major 7th · also written A#maj7 · Bb–D–F–A
Bbmaj7 is the Bb major 7th chord: Bb–D–F–A. Its sound is smooth and dreamy — the lush, jazzy color heard in ballads, neo-soul, and bossa nova. It's also written as A#maj7 — same notes, same shapes, different spelling.
Bbmaj7 takes the plain Bb major triad and adds the major 7th (A), one half-step below the root. That single note transforms it from a campfire chord into the lush sound of jazz standards, neo-soul, and city pop. It works as the I chord in Bb major and the IV chord in F major.
The most common way to play Bbmaj7 is the emaj7 shape at the 6th fret (6 8 7 7 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.
