I would like to offer a really heartfelt appreciation for Don Julin's on line lessons titled Mandolins Heal the World. If you're looking for on line instruction videos and / or Skype lessons, Don's site is, in my opinion, incredibly useful and well done. I have plinked for personal enjoyment off and on for a few years. Always in the background have been questions that all have the common denominator "How did they DO that?". Don's collection of his own instruction plus those of other great teachers, assembled in one place, will answer that question for just about any music type or style you can imagine. It is also an excellent, excellent site for beginners or anyone who wants to "backup and get it right". This is a GREAT resource! I'm so glad he is willing to share this knowledge!!!!!
