Hey Everett,

All you really need to do is determine what your ideal key is and go from there (mine is actually Bb and it took some hits and misses to determine it, though I can also sing in G and D# depending upon the chord structure). If you play an instrument, it's certainly easier, but even if you don't, you can still find your comfort zone.

There is no "normal" for men or women. For us women, wouldn't we love to all have the range of Christina Aguilera?! Not gonna happen. My range has (sadly) changed from year to year and even lessoned over time. Outside factors have contributed to it.

My best advice is to find your comfort zone and don't worry about the rest. Find your ideal key and go from there.

JMO.
