I'm not much of a one for the spotlight: I'm more of a joiner-in. Thus I never sang much, I just used to play along with the singers.
That preferred role changed through necessity. I've run an acoustic music session at my local pub for the last 5 or 6 years. The pub is tucked away in the middle of nowhere so it is a challenge to get enough singers to fill an evening. The old rule that if one wants something done one has to do it oneself kind of comes into effect in a situation like that. I had to start singing.
I thought I was dreadful. Although I can sing in tune better than I expected, I think my voice is harsh. Also, as I have a limited range I tend to belt the songs out at some volume as I find high notes difficult to reach quietly. I also have problems singing and playing at the same time if either the vocal line or the accompaniment have any unexpected rhythmic blips. I am easily thrown off.
All that said, I do now regularly sing in front of an audience. People seem, for some inexplicable reason, to like it. My singing gets described as "strong", "dramatic", "emotional", "loud", "powerful" sometimes even "pretty good". These people obviously apply different criteria than I do when they define "good". However, I agree with "loud".
If asked to sum up my singing I would probably say that I seem to get away with it most of the time.
I appear to have become quite well known for a kind of catch-phrase. It started off as a sincere apology, but is now just something that is expected of me. As I leave after a session or gig I call out: "Thank you very much. I'm sorry about the noise".
For the record, I'm with Salukulady and JJ. Screw it - if you have a voice of any kind, just sing and have the time of your life.
