Watch the Hangin' Around 12 online guitar lesson by Andy Aledort from 30 Beginner Slide Blues Guitar Licks You MUST Know
Here's a good example of how to get more out of the 12th-10th fret position when playing in an open A tuning. Let's expand our lick idea to a four-bar lick, kicking off the phrase on the A root note sounded at the 12th fret of the third string, and then moving down to the lower strings, and then back up to the higher strings, settling once more on the A root note to finish the idea. This lick affords the perfect example of a common slide guitar approach, which is to emulate the sound and feel of blues harmonica. Duane Allman often said that, when playing slide, he was simply trying his best to sound like harmonica great Little Walter.
