I learned how to play the Cello.  I'm not the greatest there ever was but it brought me more than I had ever imagined.  First it taught me how to read music.  Always a useful skill.  Secondly, Cello is usually a background intrument.  From playing it, I have gained a respect for the background music.  From it I tend to listen to just the music.. its rare for me to hear everything a band says, as i'm too intune with the music.  The third is simply that i also like to listen to classical music along side with Godsmack, Manson, Reel Big Fish... everyone
