From aunt Annie's alligator to zizzer-zazzer-zuzz, these exercises are intended to be used by singers of all ages in school and church choirs. Use them to improve vocal skills and develop technical and expressive expertise in order to enhance the musicality of their performances. The focus of some of the exercises is on vocal development, others call attention to the accuracy of consonant articulation or to the perception of expressive devices that are related to the text and phrase structure.
