just to help out a little...
"Glitter and Be Gay" is the highest note in musical theatre for women and it is the E flat above high C (as in the C above the staff)
the highest note ever for a woman occurs in the opera Aida.. Amneris sings the F above high C( as in the C above the staff).
Kristen sings C's (as in the C above the staff) in Wicked- nothing higher... but she does it very well.
and Shoshana certainly mixes the end of "Bless the Lord My Soul"... very well.
as far as high belting goes- we are forgetting an important thing- we are the audience and not the singer- when Sutton Foster gave a masterclass at my school this past year (The University of the Arts) she let us all in on how she mixes many of the acclaimed belt notes that people love of hers. This is not a bad thing- this is a healthier approach to an exciting sounding kind of singing. So when we say that .. for instance "Defying Gravity" is the highest belt note with the Gs and Fs at the end... we may not know that someone like Eden uses a mix (influenced from the chest) to hit those notes.
so - there are some high notes in shows.. and it becomes the actor/actress's choice as to their approach of singing it...
predominantly anything around and above a D is considered a high belt... but no lies... rarely is anyone truly truly "belting" from a chest voice in that range...
so that said- yay for high singing and the pursuit of its glory!
hahaha.
happy singing to all!
There's nothing you can know that isn't known.
Nothing you can see that isn't shown.
Nowhere you can be that isn't where you're meant to be.
