Where Abm(maj7) fits
Abm(maj7) is i(maj7) in Ab minor. Most often it is a passing chord in the descending line Abm → Abm(maj7) → Abm7 → Abm6, where one voice falls a half step at a time from Ab. The first four bars of the jazz standard "My Funny Valentine" (Cm, Cm(maj7), Cm7, Cm6 in C minor) are exactly that line.
