How to use the Bmaj7 chord
The Bmaj7 chord is built from a root, a major third, a perfect fifth and a major seventh. Start at the root B and stack the intervals to get the whole chord: B, D♯, F♯ and A♯. The same formula gives you the chord in any other key.
Major seventh chords colour jazz standards, bossa nova, soul and modern pop. They most often serve as Imaj7 or IVmaj7 in a major key to add warmth without changing the function.
In major keys Bmaj7 is the Imaj7 in B major and the IVmaj7 in F♯ major; in minor keys it's the IIImaj7 in G♯ minor and the VImaj7 in D♯ minor.
How Bmaj7 differs from similar chords
Bmaj7 is not B7: its seventh sits a half step below the root rather than a whole step, so it floats instead of pulling. Next to B6, which adds the sixth instead, Bmaj7 sounds lusher and more modern. The major seventh is the only note that separates it from a plain B triad.
Where Bmaj7 is used
A major chord is at home as a tonic, and just as useful as the IV or the V of a neighbouring key. Each progression below is written in the key its numerals name.
