**LONG POST**
I'm not a good singer and I am untrained.
Two weeks ago I was asked to do the song, "Friend of God" by Israel and New Breed in it's original key, the key of E. I have a low speaking voice so I did not think it would be a big deal. I tried singing it, with no vocal warmup, at practice. I did not have a microphone, so I had to sing above the instruments so that I could be heard. I couldn't move closer to the choir because I was playing one of the instruments. I noticed a small strain in my voice so I asked the choir director to ask the altos to sing the melody during the chorus so I wouldn't have to sing at that point and to give my voice a short break. She never taught them the part so I was stuck singing the entire song. By end of the second time singing the song my voice started to flip and I started to sing off key involuntarily. It only hurt a little bit and I went on vocal rest.
Last Saturday we had rehearsal and I said I couldn’t sing the song because the last time I did I had vocal issues. The choir director asked me to just try it anyway. I decided that maybe I could sing it differently and it would help. I did not want to change the key because all the musicians were not there and I did not want to change the key and have them up late trying to relearn the song for the next day. So I could not find a different way to sing it and my voice started to flip again. I sent the choir director a text message later that day telling her I could not sing the solo. She wasn't too thrilled nor did she believe me, but she got someone to do it in my place.
I’m trying to figure out what exactly happened to my voice. Both times I did not warm up. If I did would I had had the same issue? Since, I lack proper vocal technique would warm ups have had any bearing on how I sung? Then again I was thinking, you know how when you exercise and you use muscles you do not usually use it hurts for a while, but after exercising them for a while it gets better? Maybe that is what happened. If I do warms up and practice singing in E, will it get better? Was I, simply, singing outside of my range?
Thank you for your time.
