- AbM3Cm3EbM3G
Ab Major 7, written Abmaj7, is built from Ab, C, Eb and G: the root, major 3rd, 5th and major 7th.
Its 3rd and 7th, C and G, are its guide tones: they say what kind of chord it is, so voicings are built around them and the root is often left to the bass.
In the progressions here, Abmaj7 is the Imaj7 of the Major ii-V-I Progression in Ab, the IVmaj7 of the Minor Plagal Cadence in Eb, the ♭IIImaj7 of the Tadd Dameron Turnaround in F and the ♭VImaj7 of the Coltrane Changes in C.
