Watch the Boogie-Woogie Blues 1 online guitar lesson by Jeff McErlain from Blues Survival Guide: Rhythm Edition
Blues is often about what we don't play. Frankly, all music is like that, at least the good kind! I am using the traditional boogie woogie feel here as the underlying pulse and working around it. Very often in blues tunes the "riff" of the tune is on the I7 chord, in this case I am playing something similar to Muddy Water's "Champagne and Reefer". The riff is a simple motif based on an E minor Blues scale, this is a perfect example of that ambiguous minor 3rd that is so important to the blues. On the IV7 chord I am using some slight variations on the boogie pattern, the V7 is straight forward as is often the case. In the last measure I used a cool classic turnaround.
