Fortunately, there's always Bach...

Classical radio stations often play Johann Sebastian Bach's "Sheep May Safely Graze" on Christmas, but it's comforting to know that it's just as moving on any other day.  One caution, though: If you're listening to it while wrapping presents on Christmas Eve and getting frustrated at your inability to wrap them symmetrically, it's best to avoid shouting, "Arrrrrrggggghhhhhh!"  I did this two nights ago, and suddenly, the piece shifted into a minor key.  "Sorry, sheep," I said, when I realized what had happened.  "I didn't mean to startle you."  Fortunately, the piece then went back into its original major key.  Apparently, the sheep were content again.
