Playing While Standing

This is a 2.03 minute video response from Mark Lincoln on Feb 3rd, 2009

Question:

"Hcso asked "Instructors, My question may sound a little dumb but I've been playing and practicing the guitar long enough in the sitting position, that when I stand up with it everything is off. I'm hitting the wrong strings and not finding my powerchords like I can from the sitting position. This is very frustrating. Has anybody else had this problem. Do I need a strap that brings the guitar closer to me? I don't know what else it would be. Any help is welcome Josh.""
