Okay, opera nuts, what female opera solo is this?

It has been stuck in my head all day long, and it’s only two stanzas or so, and it’s killing me. I thought that it was “O Mio Babbino Caro” by Puccini, but after hearing it I have determined that it is just the same key.

I know that this isn’t much to go on, but I know the notes in one of the parts. I feel like it’s more of a modern piece, and it may not even be opera. It just has that feel to it.

Anyway! The notes are “A G# E, A G# E C# E”.

oh, and I’ve missed you guys. it’s been a long time.
