There are only so many different muscles and useful motions with which to move the pick. It seems to me that Troy and his team have pretty much completed covering the area of the different ways to alternate pick rapidly and accurately, aside from a thumb/index finger technique. I’m curious as to what Troy and his team believe they still have yet to cover on the subject of accurate, fast ways of alternate picking. What more could be left to still explain that they haven’t explained already?
I ask this because if they are finished or near finished explaining efficient alternate picking, then what would be some subjects they’re interested in covering next? The best ways to alternate pick seemed to be the biggest question among guitarists. Are there other areas of guitar playing they believe have just as much interest in them and as much mystery surrounding them as alternate picking once did? If so, what are they?
