- G#M3B#m3D#M3F##
G# Major 7, written G#maj7, is built from G#, B#, D# and F##: the root, major 3rd, 5th and major 7th.
Its 3rd and 7th, B# and F##, 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, G#maj7 is the IIImaj7 of the Coltrane Changes in E.
