"She's a pretty straightforward full lyric soprano"
Exactly. And she needs to learn that everything has a name. I can't stand it when people don't know the difference between "names" and "boxes".

And every person has a head and chest voice.
I hope she reads this. She is not an alto, she is not a belter, she is not many things. You have boundaries too Audra. And you have a very specific vocal type, with a name.
