I did a short little demonstration last night for my mid-semester critique. My double handed tapping chops aren't quite up to par... actually I'm kind of sloppy at this point. But I'm working on honing this so I can rock without screwing up like I do in the video. Also, note that the keyboard is being held up with a piece of yarn. That's just temporary untill I get a guitar strap for it, and mount some points for it to attach to.
