why music theory?

I ran across this page this morning, and wanted to share.  I've been saying most of this for a long time.  More importantly, I actually USE the theory skills mentioned in the article, nearly every day.  Especially as a church organist, knowing how the hymns are put together allows me to improvise on, reharmonize, and otherwise make things a bit more interesting, or more supportive of the words.
