Nice method of visualising notes in time and the resulting temporal structure of the music. Blurb from the video below:

For every note played on the keyboard a new visual element appears in form of a stripe, which follows in its dimensions, position and speed the way the particular key was stroke. Colours give the viewer and listener an impression of the harmonic relations: Each key has it’s own color scheme and “wrong” notes stand out in contrasting colors.
All stripes stay and overlap each other in an additive way, so at the end a kind of pattern remains – a summary of the music – which will be always unique since the notes of the composition aswell as the interpretation of the piano player are influencing the outcome. Furthermore the piano player can switch between the standart 2d view and an additional 3d view of the visualization while playing.
