Gb13(#5) Guitar Chord - Guitar Chords Chart
Every letter name from A to G appears once in Gb13#5, the Gb thirteenth sharp five chord: Gb, Bb, D, Fb, Ab, Cb and Eb.
That happens because the chord is built by stacking thirds. Its enharmonic twin is F#13#5, which sounds exactly the same. Fb and Cb make this spelling a theoretical one.
The raised fifth D and the thirteenth Eb are a half step apart, a tight interval inside the chord. The raised fifth is the only note that differs from a plain dominant thirteenth with the same root.
Gb 13th with sharp 5th guitar chord is also written as Gb13(#5), Gb13#5 or Gb13+5.
