Last lessons had us playing solo on the B and high E strings fretting 4 and 6. So I'm just messing around today playing and hammering on and pulling off randomly, and I hear Stairway to Heaven coming through!!! Cool I thought.So I look up the tab for the song, and it's played right in there with a few notes outside of 4 and 6 frets.This is the kind of thing that TAC does for you..... trains your ear (Fretboard Wizard flashback).Man... what a great feeling.
