Today's Piano Puzzler

This week's contestant is Cynthia Sibitzky from Haslett, Texas.  I don't get the sense that the hidden song is really all that hidden, and you get it in about three seconds -- and only that long because there's a bit of an introduction into the piece.  Though it's very lovely.  As for the composer style, I had a choice between three people who are somewhat similar.  The contestant's first guess was mine, as well, but...we were wrong.
