I love to sing.  I am a vocalist.  Do you like to sing?
I think it's fun, but I am terrible. I really wish I was better!
I actually surprised everyone in my family when I declared a vocal major in college, singing in lots of Opera's.
That is really cool. Have you been singing your whole life or did you find out you were good later on>
I used to sing as a kid to my vast record collection, and then spent some time in choir in highschool and college, but everyone thought I would become a piano major when I went to college.  Surprise!
Do you think practicing can make a big difference, if you aren't naturally good at singing?
OH yes, singing can be formal or informal.  I believe that regardless if you are naturally good or not naturally good, practicing is extremely beneficial...even if you don't perform somewhere, sometimes singing in the shower, or the car is fantastic!
