Watch the Dom7#9 Chord & New Riff online guitar lesson by TrueFire from Play Rock Guitar 2: Rhythm & Lead Fundamentals
The Dominant 7th #9 chord is one that is often associated with Jimi Hendrix. As a matter of fact, a lot of players simply call this the "Hendrix chord". This is a cool blues rock groove to work on and put this chord into use. Start off just getting a good feel for playing the chord by itself especially if you have never played it. Then when you get it down, work on putting the whole thing together and playing it with the jam track.
