MusicAnimationMachine

From the website...

: The Music Animation Machine display is a score without any measures or clefs, in which information about the music's structure is conveyed with bars of color representing the notes. These bars scroll across the screen as the music plays. Their position on the screen tells you their pitch and their timing in relation to each other. Different colors denote different instruments or voices, thematic material, or tonality. And each note lights up at the exact moment it sounds, so you can't lose your place.

: The experience of watching the Music Animation Machine can be a remarkable awakening to the inner structure of music, especially for people who are sensitive to music but lack the training to "see inside" a conventional musical score. A tool for listeners of all ages.

This is a representation of the first ten bars of Bach's In Dulci Jubilo, from Das Orgelbüchlein.

Furthermore, the MusicAnimationMachine can colour the bars based on their pitch class.

From the website...

: Harmonic coloring assigns twelve colors from the artist's color wheel to the twelve pitches of the musician's circle of fifths.

: Above are four bars (23-26) of Chopin's Nocturne, Opus 27, No. 2 in D-flat major. This excerpt modulates chromatically, ending with a V-to-I cadence (violet-to-blue in the bass line).

There's also a QuickTime movie of Bach's In Dulci Jubilo on their website that's fun to watch.
