Watch the 10th Story Walkup online guitar lesson by TrueFire from Play Acoustic Guitar 6: Lick Lexicon
10th Story Walkup - E Lick 6 is a video guitar lesson presented by David Hamburger and is sourced from Fingerstyle Blues Factory.
Tenths, or an octave plus a third, are closely related to sixths. If you took each note of this lick on the low E string and just moved it to the high E string, you'd wind up with a sequence of sixths on the third and first string. You could also think of this lick as a way of using the third string to harmonize the walking bass line on the low string. A lick like this can come in handy when you want to break up the constant drone of the low E note on the I chord.
