Vocal Ease is a series of 13 exercises complied by Dave Williamson as a result of scanning the globe for over 30 years in an effort to identify a warm-up sequence that really works. The exercises in this collection are the best of the best at actually preparing the voice for singing. These exercises are very versatile: They can be used either in the context of a choir rehearsal, or individually in a choir member's home or car. Wherever you use them, they'll work, and they'll work great! Dave makes it easy for you to teach your choir these warm-ups. In the Directors Edition, each exercise is prefaced with Dave's explanation of its purpose and includes a demonstration by Dave with his choir of how it is to be performed.
