Thanks, Randy. Most of what I've done so far didn't require much pushing - as a matter of fact, the reason I decided to give it another try is that I felt comfortable and in control in that range for the first time in quite a while.
I tried a couple of other songs I'd recorded the music for over the last few years, mostly covers and realized that it's always a good idea to consider vocals and a comfortable key before you get too far in... :/
I'm kind of hoping to at least close the books on this - have those few songs completed, but just for me. I have zero ambition as a singer - all that's unique about my voice are the quirks. Anytime I venture out of the muddy lows, I sound a bit like Lennon, and as much as I liked him, I don't see the point in being a sound-alike.
My wife's the singer, anyway. Best case scenario, if I could provide back vocals for her, it'll be an honour. Worst, I can still be musical director, arranger, guitar player. And devoted husband. :P
