2+ players. At home players listen to a piece of colorful, captivating music, and then create some kind of graphic score that represents the piece in whole or in part, but in any case may not exceed two pages. When players get together, they exchange pieces without knowing what the original music was that the graphic score was based on. Let each player have a crack at playing a solo of each score. Then repeat, as a duet (or trio or quartet). After this the composer of each score may reveal their original source.
