All buttercream. Chocolate frosting is from the chocolate syrup frosting recipe. YUM! The template for the sides reminded me of a music stand. Boy, did this cake bring back memories of long, long ago, transposing music in college (yes, I was a music major). Yeah, I know, the flute is crooked, but you can't tell so much when looking straight at it. The music is "excerpts" for Pachelbel's Canon - my absolute favorite piece - written for the flute.
