Watch the The Hendrix 6/9 Chord online guitar lesson by Reeves Gabrels from Rock Inside Out

What led me to using voicings in fourths was the overlap between them and Hendrix’s playing. Hendrix would use the 6/9 chord in improvisational settings to get out of a solo and get back to the top of a verse. I also use the chord, without the root, to leave room for the other instruments.
