What would you call the opposite of falsetto?

Chocolate rain?

Vocal Fry, Glottal Fry or strohbass according to Wikipedia.

haha PnT. I laughed :)

true voice or your natural singing voice without closing off the vocal chord.

I don’t think there is such a thing. There’s head voice (falsetto), and chest voice (your natural voice). And if you can’t reach any lower than that, no wait! I just remembered, you know how your voice gets higher with helium? One day I inhaled propane and my voice got LOWER. Kids, don’t try this at home.

Truetto.

Basso profundo~

I agree with stratman. Every voice has a break point near the top of its range. Anything above is the falsetto, and below is the chest voice. Male voices generally have a gap of a couple of tones in between the two, which is why the falsetto seems to stand out to people. Females have it to, but the break is generally much smaller, making it easier to miss.
