What Gm(maj7) is made of

Gm(maj7) (G minor major seventh) is built from the notes G, Bb, D, F#, with the interval pattern 1, b3, 5, 7.

Stack 1, b3, 5 and 7 on a root of G and you get G, Bb, D and F#. 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 Gm(maj7).

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

Spelling: the notes above are written the way a score would write them, not simplified to the nearest piano key. That is why this chord is spelled with B rather than its enharmonic equivalent.
