Musical comedian Bill Bailey demonstrates the difference between major keys and minor keys and how important they are to the songs we know and love. "Für Elise" loses all its emotion when transposed to a major key, and "The Star Spangled Banner" becomes totally foreign in a minor key. Besides all that, this clip from his routine at the Prince's Trust Gala last fall is really funny, too. -via Laughing Squid
