So Where does singing begin?

Does singing begin in the diaphram, or in the throat, in the beginning of the day when in the shower, or in when one makes a committment to practice in a practice room? No, it begins in the mind. I am more convinced that a singer's ability to sing in a natural, healthy, and intelligent manner is dependant on the "inner ear". Can the singer hear a world of music inside that skull?
Well, let's begin developing the "voice of the mind".
