Bmaj7 Guitar Chord
B Major 7th · B–D#–F#–A#
Bmaj7 is the B major 7th chord: B–D#–F#–A#. Its sound is smooth and dreamy — the lush, jazzy color heard in ballads, neo-soul, and bossa nova.
Bmaj7 takes the plain B 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 B major and the IV chord in F# major.
The most common way to play Bmaj7 is the amaj7 shape at the 2nd fret (x 2 4 3 4 2, 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.
