The G#m7b5 chord (G sharp minor 7 flat 5, or G sharp half diminished) contains the notes G#, B, D and F#, which is the 1 (root) b3, b5 and b7 of the G# Major scale. It can be viewed as a G#m7 chord with a flat 5 or a G# diminished chord with an added b7.

The half diminished chord can sound like a very dissonant chord, when played in isolation. However, when played in the context of other chords, it can sound beautiful. G#m7b5 is the 7th chord in the key of A Major. Try playing an A chord, then an G#m7b5 chord and then return to A. This is an example of how G#m7b5 can sound beautiful in context.

The G#m7b5 chord is most commonly played with the root note on the 4th fret of the 6th string (2nd shape in the picture below).
