ACKNOWLEDGMENT |

|
I am indebted to many earnest advocates of the cause of vocal education; fine friends all, whose generous encouragement and advice were of inestimable value to me during the years of preparation for this study and while gathering the materials that were essential for its completion. I feel especially grateful for the steadfast guidance of Professors James L. Mursell, Helen Walker, Carter Alexander, Norval Church, and Harry R. Wilson, and for the loyalty and heartening friendship of Dr. James F. Bender. I trust this treatise will vindicate their faith. |
