The images reflect the light emitted from the piano.
It's like a multicolored paper. The notes of each character and each sound. Emitting gradually drifted away from the piano. In fact, even when we play or watch a piano. We could not see the light piano notes. But when I close my eyes Imagine and try to imagine the feeling, combined with songs. Perhaps we might see the light piano floated out of it.
I use color and independence. Color is a combination of sensitivity and strength. This reflects a combination of fantasy and reality.
