Watch the Southern Comfort online guitar lesson by Jeff McErlain from 50 Blues Rock Guitar Licks You MUST Know
One of the hallmarks of Southern Rock is the use of the major tonality, more specifically Mixolydian. Mixolydian is the scale that is used over a dom7 chord and it creates a happy yet bluesy quality. Many people associate this sound with jam bands and Southern rock classics like Jessica, Blue Sky, and of course Sweet Home Alabama. A cool thing to see is that the major pentatonic scale can be found inside of a mixolydian scale so, wherever you can use mixo you can use the major pentatonic based on the same root.
