Where Bmaj7 is used
Bmaj7 is the one chord (Imaj7) in the key of B major and the four chord (IVmaj7) in the key of F♯ major. Take B and add one note, A♯, which sits a half step below the root. That close pair of notes gives the chord its soft, open sound, and you hear it a lot in jazz, soul, R&B and lo-fi.
