G#13

— About this chord

G# dominant 13th (1-3-5-♭7-9-13): the full jazz-blues dominant color, stacking the 13th above a dominant 7 for rich turnarounds and shout choruses. A staple in blues shuffles, big-band voicings, and funk/soul horn-inspired comping. On guitar the classic movable A-shape grip lands in the upper neck for G#, while compact low-position grips let rhythm players sound the color without leaving open position. Resolves naturally to C# or substitutes for a plain G#7 to add sophistication. Also searched as Ab13, G#dom13, A♭13.
