What Bm(maj7) is made of

Bm(maj7) (B minor major seventh) is built from the notes B, D, F#, A#, with the interval pattern 1, b3, 5, 7.

Stack 1, b3, 5 and 7 on a root of B and you get B, D, F# and A#. That interval recipe is what makes the chord a minor major seventh chord — move the same shape to another root and the character travels with it, which is why Cm(maj7) sounds like a transposed Bm(maj7).

Minor-Major 7th: Sinister, James Bond-ish. Tonic of harmonic minor.
