Watch the Playing By Position online guitar lesson by TrueFire from Play Blues Guitar 7: Slide Approaches
Playing By Position - Concept 8 is a video guitar lesson presented by David Hamburger and is sourced from Focus On: Standard Tuning Slide.
Playing by position refers to taking the closed position box and moving it around the fretboard to match whatever chord you're on at the moment. It's a great way to use the slide to arpeggiate or spell out notes specific to the chord changes. And as you'll hear, it's a very familiar and compelling slide sound, and will come in particularly handy when we get to doing some Ry Cooder-style moves.
