See Charlie McMahon in a class session on a You Tube Clip here:  http://youtu.be/ozmx1t7Erfs   Charlie will hold another Didgeridoo Essentials Course at Tali Gallery for four weeks (2 hours a session), commencing 24th June.  Circular breathing required in playing Didge or Yidaki, is a wonderful way to strengthen the lungs and is subsequently a great benefit for respiratory health!   Book on this link through Sydney Community College: http://www.sydneycommunitycollege.com.au/course/ARMU35
