About E 7th Sharp 9 Chords

The 7♯9 chord — the 'Hendrix chord' — combines a dominant 7th with a sharp 9th (enharmonically, a minor 3rd). This creates a crunchy clash between the major 3rd and minor 3rd. Jimi Hendrix's 'Purple Haze' made this voicing iconic, but it appears throughout blues, funk, and jazz.
