Аннотация:The purpose of this essay is to improve the way we talk about organizational improvisation, using the vehicle of jazz improvisation as the source of orienting ideas. I start with two brief descriptions of the complexity involved when musicians compose in the moment. Then I review several definitions intended to capture holistically what is happening when people improvise. Next, I take a closer look at selected details in improvisation, namely, degrees of improvisation, forms for improvisation, and cognition in improvisation. These understandings are then generalized from jazz to other settings such as conversation, therapy, and relationships of command. I conclude with implications for theory and practice.
