Theory
The mmaj9 chord combines minor third, major seventh and major ninth. C mmaj9 = C-E♭-G-B-D, A mmaj9 = A-C-E-G♯-B. The contrast between minor third and major seventh (characteristic of mmaj7) is enriched by the major ninth. This rare chord is used to create sophisticated harmonic colors in modern jazz and film music.
