[me, myself, and I]

Like Whitney Houston, she can control and manipulate her vibrato, like speed it up or slow it down depending on the emotion she wishes to convey. But that's VIBRATO. What about VOCAL WEIGHT?

Are there any singers, pop or classically, who can manipulate their vocal weight to give that sense of more lyric or more dramatic voice? Like they can make their voice darker and bigger when they sing dramatic pieces, yet they can also make it lighter and sweet-sounding when they do lyrical pieces?

And I don't mean manipulate your vocal weight as in BELTING or PUSHING your voice beyond your natural singing capacity thus creating a strain to your vocal chord (coz it can damage your vocal chord). What I mean is a NATURAL singing voice that is so flexible and versatile, it can change its vocal weight easily without any strain & flip-flop between the heavy big singing voices to light lyrical voices.
Could there be such a thing? Are there any singers who have that sort of quality in their voice?
