This is an outstanding book from one of the true masters of the dulcimer. The book deals with many of the most important aspects of developing effective technique. Much of the information won't be found in any other books. Exercises and etudes are extremely useful for developing the techniques covered. Highly recommended.
Aaron O'Rourke - Faster, Cleaner, Better
I've always had trouble playing fast, however with the tips and tricks Aaron laid out in this book I am starting to get better! The practicing techniques he uses are real easy and really do help. Practice really does make, well maybe not perfect but at least better!
