Vibrato Workbook by Dr. Chris Potter
World-renowned flute pedagogue Dr. Chris Potter has provided the flute world with a method book meant to provide structure for players who wish to develop the expressive tool of vibrato, adding warmth, character, energy and atmosphere to their playing. After working with her students for many years, Potter has developed exercises meant to help players develop control of the air supply to produce vibrato. Flute players will be glad to see that this aspect of flute technique is so well-addressed in this book.
