E7#9

— About this chord

E7#9 is the legendary “Hendrix chord”—a gritty, funky dominant voicing where the sharp ninth clashes against the major third for a bluesy, slightly dissonant snarl. Made iconic by Jimi Hendrix in songs like Purple Haze and Foxy Lady, it's a staple of funk-rock and blues-rock rhythm playing. On guitar it's most famously played as a compact movable shape with the root on the fifth string, though open-position variants exist too. Functionally it works as a dominant chord with extra bite, often used as a tonic-substitute stinger in blues-rock. Also searched as Edom7#9, E7(#9), the Hendrix chord.
