Watch the I'm a Schoolboy Too online guitar lesson by Corey Congilio from Blues Guitar Fakebook: Rhythm Vol. 1
Teaching this song is a guilty pleasure for sure. This progression comes from the song "Good Mornin' Little Schoolgirl". I first heard Junior Wells do this song, but many other modern blues artists have covered it as well. This another great example of a melody based rhythm part.
For the first pass, I stuck to the traditional melody line as often played by Buddy Guy on the original recording. The second pass gives you more of an example you might play behind a soloist. You'll need to learn how to mix up your rhythm parts behind soloist, so I thought this tune was a good way to demo that.
