In many ways, most Fluxus 'scores' (for music or other kinds of performance and/or composition) are fairly legible as scripts for performance/enactment; i.e. the text comes first and the performance after (if at all). Certainly, one of the interventions (and charms) of Fluxus scores were the openness of the scores, where interpretation and chance were much more important than following the letter of the law, as one might in traditional sheet music, for example. As such, reading Fluxus scores as performance texts allows us to see how writing can activate art/life works that writing cannot contain or control.
