There is an old beat up piano in the depths of the band room. It's out of tune and most of the keys are broken. The top is broken off, exposing all the inner working of the machine. The paint is chipped, some keys are missing, and the wood is scratched.
"Life is like a piano, the white keys represent happiness and the black show sadness. But as you go through life's journey, remember that the black keys also create music."
