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. 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.
