This study's purpose comprised establishment of bases for determining voice range norms, means, and extremes; concomitant with ascertaining expected incidence and degree of mutation through available school records. These standards were derived through measurement of height, weight, dentition, hip and shoulder breadth, voice range, and biotyping of 907 children of ages eleven to eighteen years. [TRUNCATED]
