Watch the Funk: Technique 1 online guitar lesson by Robbie Calvo from RhythmCraft
This is a really great groove to jam with your band or friends using a chord shape that you may already know, E7(#9). This chord is often referred to as "The Hendrix Chord". It's the chord used in "Purple Haze".
We are going to play the groove first using just the E7(#9) and then we are going to add an F#7(#9) and a B7(#5) as a 2 beat turnaround. If you'd like, you can think of this progression as a II -V -I progression using altered dominant chords.
Make sure that when you are playing the E7(#9) you utilize the low E string as a bass accent on the first beat of each bar. You can do this by allowing your thumb to un-mute the low E when you strike the string on the downbeat.
