The late Berton Coffin's teachings and writings established him as an international authority on vocal pedagogy. Professor Emeritus, University of Colorado, Boulder, he also lived and taught in Europe from 1976 to 1983-in his private studio in Vienna; during summers with the American Institute of Musical Studies in Graz, Austria; and in twenty-one opera houses in Austria, Denmark, Germany, Italy, and Switzerland. He presented master classes in the United States and in Europe and served as a visiting professor of voice at U.S. universities. Dr. Coffin, baritone, held academic and professional music degrees from Columbia University, Eastman School of Music, Chicago Musical College, and Earlham College.
Coffin's work provides an invaluable aid for voice teachers and choral conductors alike in helping singers achieve optimum resonance. * Choral Journal *
