I want to do something artsy, but I don't think I have a creative or musical bone in my body. How do I get started?
Find a support group. Look for a local organization that is willing to provide you with the opportunities you need to gain experience. Some great examples would be church choir and community theater... they are always looking for volunteers. There are many ways to get experience if you are willing to put yourself out there. Find people who care enough to give you honest and constructive feedback about what you are doing wrong and how you can improve your skills.

You could even volunteer to help with music classes at a local school. You can learn a lot by teaching others.
