Beginning in the early twentieth century, composition branched out into a variety of new representations, the most common being the graphical score. Cage's _Variations II_ is a prime example, utilizing only dots and lines as its basis. A potential downside to these new methods of representation is the intense burden it places on the performer to define the parameters for the realization. We have created an interactive version of Cage's piece, called here _Variations 10b_, where a performer can change the score and get immediate feedback as to the result. We hope that both listeners and performers will develop a more nuanced understanding of the score through the use of the interface.
