as someone who is a hardcore mariah fan since minute one,,,,literally the first 4 seconds out of her mouth back in '90 when I thought I would be the next linda ronstadt,,,,and was graduating with music degrees and studying w/ronstadts coach in san fran.....and now of course am a nobody that got no where in music and am over the hill but still sangan I am amazed and still hanging on to following my diva icon mariah's career.fascinated with her techinque and battling a long battle with a jaw injury from orthodontics i studied relentlessly to understand how she made sound.....ultimately it is her magnificent EAR that "makes" her voice....as it MAKES all of our voices....are her cords weathered or strained at times???? YES but when well rested SHE STILL can outtsing ALL of em/us!!! http://www.singsnap.com/karaoke/r/c36407027
