First Principle

Voice is speech, and is produced by the mouth, not by the vocal cords.   The vocal cords produce only sounds (primative vibrations) which are transformed into vowels and consonants by a phonetic process taking place in the mouth, and giving origin to the voice.

Second Principle

The full extension of the natural range of the voice is produced only by using the minimum tension of the vocal chords and the minimum breath required for each tone.  This establishes a correct mechanism of voice production.

Third Principle

Breath is an indispensable factor in voice production, but it is not the essential power which develops the voice as it is taught today.  On the contrary, the function of singing develops the breathing apparatus and its power, just as any physiological function develops the organ from which it takes origin.  Therefore, singing develops breathing, not breathing, singing.

Fourth Principle

Resonance is the most important factor in voice production.  It furnishes to the voice volume and quality, and emphasizes it loudness.  To rely on resonance rather than on force is essential for producing a big and pleasing voice.

Fifth Principle

Speaking and singing are similar functions, produced by the same physiological mechanism; therefore they are the same vocal mechanism.

The speaking voice acts as the substantial factor of the singing voice and constitutes its real support.  Singing, it its very essence, is merely speaking in musical rhythm; hence no correct singing can exist without a correctly produced speaking voice.

Sixth Principle

There are no registers in the singing voice, when it is correctly produced.  According to natural laws the voice is made up of only one register which constitutes its entire range.
