The major point was that when you create a song, you have a rough draft, like a diamond that has been unearthed. However, it's not ready to be shown off yet. It needs polishing, and songwriting workshops are designed to help with that.
I've been writing songs since 1970, and this will be my first workshop. I can't wait to see what changes I can make in editing and tweaking my songs! Think about your own work and how you can make it more polished. Check out the CSA website at http://www.ctsongs.com/ and find out for yourself!
