I made this for a friend's birthday and it was so fun! WASC cake with raspberry filling and chocolate ganache covered with chocolate MMF tinted black. The base was made with wood, everything else is edible except for the stick holding the lid up. Keyboard made from gumpaste. Lid was made with 50/50 gum paste & fondant. It didn't dry as stiff as I wanted and started to sag so next time I'd probably make it from all gum paste. The sheet music was printed on a frosting sheet. Black licorice strings painted with gold luster dust.
