My low bottoms out around the F below middle C. I top out about an octave above the treble cleft, usually the A but in practice and warmed up, I can voccalize to the C. But, I'm very lyric, very light, so I do sound very young and hammy parts just don't work in my voice. I can hit all the notes in the Queen of the Night Aria from the Magic Flute, but it just sounds silly.
