I can pretty reliably hit the G above middle C in full voice and hold for as long as the song requires, altho I'm not thinking of any where I need to hold the G for say 4-8 beats. A few years ago, when I was practicing a lot and doing 4-5 gigs a week, I could reliably hit the G# and A above middle C. Now my day job takes precedence; which is just wrong. Another factor is congestion. In the wake of a cold I can lose 1-2 whole notes off the top of my range.

My lowest solid singing note is the 2nd E below middle C. I think of myself as a sort of bari-tenor.
