Piano Birthday Cake

Most people are always surprise to find out that I dislike to cook.  I know how to cook & bake but not to fond of it.  I prefer to just go out to eat or have a bowl of cereal.  However, I love to cook & bake for the that people I love.  In a sense, it's my love language; it's my way to tell them that I love them.
A couple a weeks ago it was a very good friend of mine's birthday.  She has been so great to me this year, and I wanted to show her how much I love & appreciate her by adding a little touch to her birthday celebration.  My friend's talent and passion is music; and thought that should be my platform.   I wanted to make some kind cake theme to music, but I also need it to keep it simple enough to achieve this-because I'm no Cake Boss

2 - 9/13 white cakes.  I baked the cake from scratch but you can use cake mix.

                                                           

white cake frosting, kit kat bars (for chord keys), dental floss (to make key lines).  I used a cardboard box that I got from my job for the cake base.  I used black wrapping paper from Party City that cost 99 cents, to wrap the cardboard base.  The last touch to it (which I really think helped pull it off) was the print out of the Yamaha logo & volume systems, and pasting them on the board.  It's no Cake Boss creation but my friend enjoyed it & had fun with it.
