1) Why are the exercises you chose important for your vocal development?

The first exercise we did was the shoulder role. This is important as in opens up the diaphragm and releases any tension you may have there. It is important for when you are talking on stage as we'll be able to speak louder and clearer because we'll feel more relaxed and your diaphragm will be open.
The other exercise we did was the neck role. This is important because it gets rid of any tension in the neck, and it allows us to stand taller which would help us project our voices on stage.

2) What's one thing I would really like to change about my voice?

One thing I'm desperate to change about my voice is my incredibly irritating lisp!
For this I will have to mainly focus on vocal idiosyncrasies.
