A7#9

— About this chord

A7#9 (1-3-5-b7-#9), the famous "Hendrix chord," clashes a major 3rd against a sharp 9th for a gritty, funky dissonance that sounds simultaneously major and minor. Ubiquitous in funk rhythm guitar, blues-rock riffing, and psychedelic rock as a tension-loaded dominant that begs for a bent-string resolution. A signature sound of Hendrix-style rhythm playing.
