Which is the highest female singing voice?

I am really good at singing people say that I sing like an angel!! people say I can be the next Mariah Carey but I just think they're being nice!! ( but probably they aren't they're just speaking the truth!! because I always say tell me the truth!! and they're like yes I sing like an angel!! so when I sing I sound very close to how Mariah Carey sings!! but now like exactly!! but almost and sometimes when I hear myself singing I forget it's me singing because I do sound like an angel!! which is very surprising!! I want to be a singer someday!! I sing songwrite act direct and sometimes model!! but I'm not a famous at this stuff but that's what I want to be someday!!)

Minnie Ripperton was also able to sing in the Whistle Register. Her song "Loving You" was an excellent example of this.

The answer is wrong! Mariah Carey, Christina Aguilera and Arianna Grande can all sing notes in the Whistle Register.

this is the closest I've ever seen majority vote be this tight in margin
