- E#m3G#m3BM3D#
E# Half Diminished, written E#m7b5, is built from E#, G#, B and D#: the root, minor 3rd, flat 5th and minor 7th.
Its 3rd and 7th, G# and D#, 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, E#m7b5 is the viiø7 of the Bird Blues in F#.
