Watch the C7 Blues Quick IV online guitar lesson by Rob Garland from Melodic Soloing: Blues Chord Tones

A quick IV 12 bar blues is the same as a standard 12 bar except the IV chord makes an early appearance in the second bar:

|C7 |F7 |C7 |C7 |
|F9 |F9 |C7 |C7 |
|G7 |F7 |C7 |G7#9 ||

Play the chords and try to see the chord tones inside them. I'll play some licks over this jam in the next video.
