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.
Soprano: Wow, I can't believe you can hit that so easily and confidently. I wish I was an alto.
He: no, i'm an alto
In opera, and especially for women, the alto is known as the contralto while singers in choirs and child singers with the same range are known simply as altos.
Strictly speaking, the alto range is really the mezzo-soprano and contralto ranges put together, mezzo soprano being the higher of the two.
"Alto Saotome, of course!"
