Rangesongs contains 75 original etudes, each with a specific target note. Practice the etudes with the target note in the range you wish to develop, moving the target note higher or lower as your range improves. This allows you to systematically develop your range and endurance over time, using musical phrasing as your tool.
Out of all the books I have written, Rangesongs has provided the most immediate and tangible return in my teaching. Students who play out of this book regularly invariably improve range and endurance within one week and those who continue to cultivate thier skills beyond that time stand to gain even more. The idea of using musical phrasing as an incentive to improve range and endurance turned out to be incredibly appealing to good musicians. I hope you find as much improvement and fulfillment with this book as I have. -the author
