My voice is something that I've always been very afraid/embarrassed to share with the world. I only sing when I'm alone and out of earshot of anyone else. I've sung for a very long time though and I've practically taught myself how to be a competent vocalist. My vocal range is versatile as well. I comfortably sing somewhere between a mid-baritone and up through the bass registers, but I can make my way up into mid-range tenor on a good day (yes, my voice varies somewhat day to day or even with the weather). I can even do a somewhat passable alto in the falsetto register but I don't try this a lot as it is somewhat of a strain and I don't want to damage my vocal chords. As an American, I've often heard that most men cannot sing the Star Spangled Banner, but I'm able to do it without going into falsetto (so I guess that means something?).
Since I'm really in to classical music, I'll sing in the car with the bass and tenor parts of some works by Mozart, Haydn, etc. which is somewhat enjoyable and it passes the time, but since I'm locked into one position, it's really not possible to breathe properly.
Maybe someday if I'm dared to do it in the right kind of situation, I'll sing in public, but right now, it's my own little plaything.
