Voice Fundamentals 

Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. The principles advocated in the following pages are not the method of the Italians, the Germans or the French, nor of any other race of singers. The writer does not believe that the myriads of different vocal problems can be solved by any stereotyped method. Voice Training is a matter of Diagnosis and Treatment. However, there does exist a System of Fundamentals that is absolutely essential to correct singing.
