Watch the One Size Fits All online guitar lesson by David Hamburger from 30 Beginner Fingerstyle Blues Licks You MUST Know

You can hear Robert Johnson take this sound up to E to kick off "I Believe I'll Dust My Broom" and to F# to start "Sweet Home Chicago". It also serves as the second half of his intro to "Kind Hearted Woman" (in Bb, either capo'd at the first fret or just tuned a half step sharp). Our version sneaks in yet another train whistle lick in the second measure before wrapping up with a cool quarter tone bend on the low E string.
