Watch the Take It Easy Baby online guitar lesson by Jeff McErlain from Blues Guitar Fakebook: Rhythm Vol. 2
This tune is interesting, as it's a standard 12-bar blues, but the I chord is minor and the IV and V are major. I love variations on the blues like this, as it can make an evening of blues much more interesting than the standard fare. On that note, as you listen through this course, take note at the variation in feels, changes, and rhythm on each of these songs. The blues was always varied...interesting blues, that is.
