Papagena had a beautiful young virgin voice, angelic and smooth. It flows, and isn’t choppy.

The three spirits were young children that also had virgin voices. It was soothing listening to them

The three women were in harmony, one was the highest of the all three, one was in the middle, and one was the lowest of all three. They sounded angelic as well when they sang.

Queen of the Night was an old soprano. She had a very superior voice, and it shook me to my core. I loved hearing her sing, though, because I would get goosebumps. She was so powerful in her singing.
