Beverly Kenney type of voice
 

Hi, have been trying to find Beverly Kenney's type of voice on the Internet but doesn't show up. Does anyone know it? I mean where she is in the contralto/mezzo-soprano/soprano scale? I suppose she is not a contralto for sure.

I don't understand much of music, but any additional info about her voice would be interesting, and will research to find what it means.
