Bitch Voice...

O Gil foi o meu primeiro professor de canto, e assim que me pôs a cantar em 1991, disse-me com um sorriso: " és uma contralto...".

"In music, a contralto is a classical singer with a vocal range somewhere between a tenor and a mezzo-soprano. The term is used to refer to the deepest female singing voice. A contralto is the lowest female voice in the operatic system. One of the qualifying characteristics of this voice is a deep and dark quality to the vocal sound.
The contralto voice has the lowest tessitura of the female voices and is noted for its rich and deep vocal timbre. True operatic contraltos are very rare.

Contraltos are fairly rare in opera, since there is very little work that was written specifically for them. Most of the time, contralto roles are limited to maids, mothers and grandmothers, but they do occasionally get notable roles, often playing female villains such as witches or playing male figures that were originally intended to be performed by castrato singers. "A common saying among contraltos is that they're only allowed to play 'witches', 'bitches', or 'britches'."
