Today's Piano Puzzler

This week's contestant is Caroline Cassil from Sutherlin, OR.  I think most everyone should get this.  You  should get the composer style almost immediately.  In  fact, you will likely get the specific piece it's based on.  The song will likely take a while -- it's well hidden, deeply integrated, to the point that I wouldn't be shocked if it got missed, but then there's a passage where, if you haven't felt lost and given up, it leaps out.
