Chord & FretBbm(maj7) — minor major seventh
Also written A#mA#mA#mA#m(maj7) — the same chord, spelled the other way.
In the formula, the numbers count steps of the major scale starting from the note that names the chord; "b" lowers a half step, "#" raises one — and a slash names the bass note.
The minor major seventh combines the minor triad with the major seventh. The friction between the minor third and the major seventh creates a dramatic inner tension.
The same chord on all four instruments
Where to use it: This is the classic suspense chord from spy movies — few notes, lots of atmosphere. It also opens the famous inner-voice trick that walks down one half step at a time: AmAmAmAm → AmMaj7 → Am7Am7Am7Am7 → Am6.
