Her singing sounds similar to Aurora's.

I'm not really sure about this one. I think because Aurora has a quite mature voice a more modern and young sounding voice like Ariels might sound nice with it. Or they could sound strange together, I can't decide.
I think with a voice like Aurora's if you pair it with another quite strong or old fashioned voice there's a chance the sounds could fight eachother instead of mixing well, so I think she might sound good with Ariel. Because Ariel's voice sounds fairly young and Aurora's sounds fairly mature it could sound like a mother singing with her daughter :)

I disagree sapherequeen, I think Aurora's and Snow White's voice are NOTHING alike. Aurora's sounds like a 60 year old woman whereas Snow White sounds like a 12 year old girl.

I think her voice would go well with Cinderella's. :)

Cinderella's hands down. Cinderella and Aurora have very mature voices and they would both be very good together if not then possibly either Snow White or Ariels.

I think either Snow or Cinderella. Aurora has the largest range, I think, and her voice can go quite high, so she'd sound good with anyone I think :)

i totally agree her voice is different from the other princesses

Mongoose09, I actually have to disagree with your comment. Aurora's voice actress was actually 16 years old when this was recorded. Also, having a trained voice does not make it sound old. This is the type of voice that is the epitome of the art. I am studying to be an opera singer, or at least sing propperly in that style, and at 16, I was beginning to sound like that. If only I could sing like that. Her voice is actually the most mature sounding because it is the most honed and perfected.
