Spelled G#, B#, D## and F#, G#7#5 is the G# augmented seventh chord, with the root, major third, raised fifth and minor seventh above its root. All four notes come from the whole-tone scale, a six-note scale built entirely from whole steps.
All 3 voicings are barre shapes, with none using an open string. The G# whole-tone scale contains all four chord tones, which makes it a reliable scale for soloing over G#7#5. Seen from the other side, Ab7#5 names the same sound with the opposite accidentals. The notes B# and D## are theoretical spellings, which is why the same sound is also written Ab7#5.
The player at the top adds a drum loop with a tempo you set, which is a simple way to play along and rehearse chord changes.
G# dominant 7th with sharp 5th guitar chord is also written as G#7(#5), G#7#5, G#7+5 or G#aug7.
