Theory behind the chord
Often called the Hendrix chord, the 7♯9 stacks a sharpened ninth over a dominant seventh. Major and minor thirds sound at once, producing the gritty clash that defines psychedelic rock and funk. On G7♯9 this structure sits on the root G, so the degrees 1 – 3 – 5 – ♭7 – ♯9 map onto G, B, D, F and A#.
