An interactive instrument for generative music visualization done with vvvv.
The setting of this installation consists of three parts: A digital piano with 88 keys and midi output, a computer running a vvvv patch and a vertical projection above the keyboard.

The visual concept of Clavilux 2000 is quite simple. For every note played on the keyboard a new visual element appears in form of a stripe, which follows in its dimensions, position and colour the way the particular key was stroke: The length and vertical position show the velocity, the stripe’s width reflects the length of each note.
By mapping the color wheel on the circle of fifths, the colours finally give the viewer and listener an impression of the harmonic relations. Notes belonging to one specific tonality always get colors from one specific area of the color wheel. Therefore each key gets it’s own color scheme and “wrong” notes stand out in contrasting colors. The more different tonalities a piece has, the more colorful the visualization will be.

ある意味で，これもクロスモダリティかな。
