Sheet Music Boss · for one very busy piano

• Right hand. The ribbon traces the top of everything the right hand plays. Every key it strikes flares and fades like a real piano note.
• Left hand. The ribbon follows the bass line, the lowest note under your left hand.
• The arch between them is the harmony. It glows white when the hands agree and flickers orange when they clash.
• The staff lines ripple like piano strings from every note played on them.
• Sparks. Harder notes throw more of them. By the end there are so many notes that the camera shakes, and the final pull-back shows the whole piece as one scribble of light.
