Stupid Question: Is It Possible to Be Missing an Octave?

What I mean is, could you possibly possess the vocal ability to sing in two octaves that follow one another, but not have the octave after that, but to then have the octave that follows the one that you don't have (the fourth octave i suppose). I wonder this because I was thinking about Mariah Carey and I've heard her sing pretty low and pretty high, but I can't recall if I've heard her sing a song where she sings in a normal soprano range (like Julie Andrews, perhaps). Maybe it's just been a long time since I've heard her older songs.

I'm not a singer, so forgive me if this is moronic. :P

I'd go back and listen, picklepie :) In nearly every one of her ballads, she utilizes the range you refer to (notationally, that tends to fall between middle line B to the C above the staff). Does her voice in this register even remotely resemble Julie Andrews', or any other legit-voiced soprano? No. She has a tremendous high belt, a great mix, and occasionally manages a nice floaty head voice, but it's never legit-sounding, which is probably why you never equate it with the soprano register, but it is. Listen to "My All", "Love Takes Time", and "I Don't Wanna Cry" for starters...

Don't worry about not being much of a singer or missing an octave or so.

Lotte Lenya made a whole career out of missing several octaves. What's more, her missing ones would change from performance to performance.
