Watch the Statesboro Blues: Ex. 1b online guitar lesson by Andy Aledort from Kings of Rock & Roll Vol. 3: Duane Allman
When playing slide guitar, intonation (playing in tune) becomes much more of a challenge as one moves up the fretboard. Duane Allman displayed an incredible ability to play in tune at the highest reaches of the fretboard, and beyond. This excerpt begins up in 17th position, but then moves all the way up to 22nd position (and higher!). Play these phrases slowly and be sure to focus on playing as "in tune" as you possibly can.
