Does a small body frame (meaning small bones and possibly small organs) or low weight affect the "power" of a singing voice?? Does a higher weight creates some sort of "pressure" or something that makes the voice sound more powerful? Is a person with a small body able to take as much air as others?
This came to my mind after watching some (about 20) videos of some singers, most of them were opera singers, but there were others like Mariah Carey. I noticed lot of them are on the "thick" side, and well, I wanted to know if there was some sort of science behind that or just coincidence.
