- AM3C#m3EM3G#
A Major 7, written Amaj7, is built from A, C#, E 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, Amaj7 is the Imaj7 of the Major ii-V-I Progression in A, the IVmaj7 of the Minor Plagal Cadence in E, the ♭IIImaj7 of the Tadd Dameron Turnaround in F# and the IIImaj7 of the Coltrane Changes in F.
