How to Play Dominant 7#9 Chords on Guitar
When learning jazz guitar chords, one essential chord every guitarist should know is the dominant 7#9 chord.
Often referred to as the Hendrix or Purple Haze chord, the dominant 7#9 chord is a blues chord because it contains both the major and minor 3rd.
Blues-rock guitarists like Stevie Ray Vaughan and Jimi Hendrix use the chord because of the crunchy tonality.
Alt and diminished scales can be used to improvise over the chord type, but most guitarists use pentatonic and blues scales.
