The female voice ranges are:
Soprano, Mezzo Soprano, Alto, Contra Alto.
Anyone who is looking for male vocal ranges:
Tenor, Baritone, Bass, Basso Profundo.
I was also researching the keys of each pitch.
Soprano: C4 to A5
Mezzo-soprano: A3 to F#5
Alto: G3 to E5 (and contralto as F3-D5)
Tenor: roughly C3 to A4
Baritone: A2 to F4
Bass: F2 to E4
Hope that helps!
