In June 2008 I purchased a natural finish didge which also came with the introductory instructional DVD. After several months of diligent effort I have become fairly proficient in the material presented on the DVD including being able to do circular breathing. What a challenge that was, but well worth the effort!
For Christmas I received the 5 CD instructional set and have been reviewing the first disc. What a great instructional method. I look forward to advancing in my level of didge playing.
