B m(maj11) Chord

How the B m(maj11) chord is built: its notes, its interval structure, and where it fits.

The B m(maj11) chord contains 6 notes: B – C# – D – E – F# – A#. It belongs to the eleventh family of chord qualities. Like every chord, it is defined by the distances (intervals) between its notes, not by any one instrument — which is why the same formula names the chord whether it is voiced on a fretboard, a keyboard, or a choir.
