Watch the Free Myx online guitar lesson by Jeff McErlain from 50 Blues Rock Guitar Licks You MUST Know
Sometimes playing over one chord can be more difficult than playing over many, especially as the rhythm guitarist. In this example I am borrowing the feel of Freeway Jam by Jeff Beck. The tune is largely one chord, G7. So what do you do? Banging on a G7 chord won't really make you too popular with the other guys in the band. So here are some ideas largely using the G mixolydian scale. This tune is basically called a modal vamp, if this sparks your interest look into the modal period of jazz by Miles Davis and John Coltrane.
