- G#m3Bm3DM3F#
G# Half Diminished, written G#m7b5, is built from G#, B, D and F#: the root, minor 3rd, flat 5th and minor 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#m7b5 is the iiø7 of the Minor ii-V Progression in F#, the viø7 of the Minor i-vi-ii-V Progression in B, the iiiø7 of the Minor ii-V to ii-V-I Progression in E and the viiø7 of the Bird Blues in A.
