— The human voice is really the foundation of all music; and whatever the development of the musical art, however bold the composer's combinations, however brilliant the virtuoso's execution, in the end they must always return to the standard set by vocal music. —
 ---Richard Wagner

“My philosophy of teaching voice is founded on the belief that singing is an extension of speech.  Obviously the assortment of pitches and rhythms used for singing are far more extensive and complicated than those used in speech, but the basic physical-mechanical processes employed by both are identical.  For me, a fine singer is able to produce a sound that is natural (speech-like), open and evenly balanced over the entire range of the vocal instrument.  A singer must also be a fine musician, linguist and actor.  While I believe that the study and eventual mastery of these skills is critically important, the student of voice must keep in mind that the primary objective of any vocal technique is to strengthen and refine that singer’s ability to express the words he or she sings.”
--William Nield Christensen
