I am a voice teacher who teaches functional singing based on balanced vocal registration. This is the key to bel canto singing and is almost extinct today. All of the great singers of the past had strong falsetto and chest coordination. That gives the chiaroscuro and freedom to the sound.




One of the earliest teachers of bel canto stated:

"The voice in its natural state is ordinarily divided into two registers, one of which is called the chest, the other the head or falsetto. I am speaking only of the voice in general divided into two registers, as commonly happens." - Mancini

Likewise, Rosa Ponselle wrote in her autobiography:

"Although there is some disagreement about the number and kinds of registers in the singing voice, I have always found it accurate, as I've said elsewhere here, to dissect the voice into "chest" and "head" components. In various segments of a voice's overall range, either the head or chest sound can be emphasized, for any number of reasons."
