Of the myriad contributions Jimi Hendrix has made to the lexicon of modern guitar, one of the most enduring is the legendary “Hendrix chord." The chord, an E7#9, was definitely nothing new when Hendrix famously used it in “Purple Haze” (Jazz and R&B guitarists used it extensively, and the Beatles featured it years earlier on “Taxman”), but its use by Jimi inspired its use by generations of guitarists in a wide range of styles.
