Such a high and girly voice. I particularly like her voice in her Oprah birthday interview (with Gladys, Aretha etc.). There you can really tell how different her timbre is from the other two.
It was high in the beg of her career but wasn't that high as it would be few years later. And now in 2023 she's just a loud high voice and I love it. That's how u know she's doing something right, if your voice is still getting higher including your tessitura.
