Anyone who has staged a show has an idea of the numberless odd things that can go wrong. We expect, of course, that they will go right. From experience and knowledge, we can conceive the contingencies in categories; they range from the personal to the institutional and the natural (as in a force of nature). Contingencies of performance are the many variables that could impact performance in any number of ways, mostly unforeseen, and even if foreseen, mostly unpredictable in effect. Of course, contingency factors are time and space dependent, as what is contingent in one context or time may be completely under control in another context or time. We need to conceive of performance as fundamentally “a changing function of multiple variables,” as Barbara H. Smith once said of value. This changing function is a concept we need to hold tightly as we navigate common challenges of performance: What is our purpose or goal? What should we perform? What are the mechanics of the performance? Where should we perform? When? And for whom? These challenges are theoretically of indeterminate and indeterminable chronological sequence, and beginning from and working diligently through any one of them is bound to lead us into the others.
