Thanks for sharing this--great sound quality! I also started life as a soprano, then had a smart teacher switch me to alto one year to force me to learn to read music better. My range was pretty wide, so I always offered to sing whatever was needed most, with my sweet spot being the mezzo-soprano. I have heard that having babies can change the voice (along with a lot of other stuff!) but I think I lost my highest notes to chronic sinus infections rather than my 6 kids.
