Singing and Voice
Often, the word "voice" is used interchangeably with "singing". Voice is not the same thing as singing, just as the sound of the violin is not the same as the act of playing the violin.
Breathing, Singing, and Life
Singing, as an aesthetic, emotional, communicative human act, fulfills its potential only when it is a true expression. As such, it cannot be forced or directly controlled.
Pier. Francesco Tosi
Oh! how great a Master is the Heart!
