The second lowest female voice.
Some women are ashamed of being an alto. There's nothing wrong with it. You can just go a little lower than the rest of the chorus.
There's also rumor going about that sopranos are overly happy bubbleheads. That's true for some, but most of them are kind, down-to-earth individuals who can go just a bit higher than the rest of the chorus. You might think I'm supporting sopranos because I am one, but I'm a fair judge, because I'm both. Not mezzo, both. There's a big difference. I have all the soprano notes, and all the alto notes, and a few bass notes ;)
So, to sum it up: Being an alto is something to be proud of.
Alto: *blasts out G1*
Soprano: Wow, I can't believe you can hit that so easily and confidently. I wish I was an alto.
