Hi Amparo, Roland White Fiddler and Forum moderator here. Sorry I missed your recent post. I agree wholeheartedly with Casey Willis that Cassey Dreissen has gone way beyond the basic Chop that Darol Anger started with. He is by far the most inventive Chop master I’ve ever heard or seen and I don’t think he is even close to finishing inventing new ways to create rhythm. Currently I see most modern master fiddlers able to execute the Chop in interesting ways so keep you eyes and ears open to all players that have mastered this.
