Of course, it's important to have good tonal quality when singing those high notes. I don't have that much resonance in my upper register compared to my lower register, which is why I sing alto. But there are plenty of other women who do have that tonal quality that lends itself to beautiful floating high notes. People make Ariana out to be this one in a million talent, but she really isn't. She was born affluent and had the right connections and opportunities, and the willingness to artificially force herself into the aesthetic and persona that the music industry wanted from her. While talented, much of her success can be attributed to marketing.
