And so I think it's most likely that the builder will also be the instrument's best player. The improvisation mentality and attitude normally enables very different people to work together. If you think of it as a language and not a style, improvisation can't be exhausted. It's elementary to human action. Attitudes and styles will always change, and are changing to suit the needs of people.
People get old, and their ideas can become exhausted, but ideas and people are also renewed.
My friend Jack Wright said he thought of improvisation as relationship in sound between people and environment. I could add that improvisation is way of working, a method. For me it is synonymous with the creative process, be it applied to art or any other form of human activity. Jack also said we are well connected in most of this playing, and when we are not we know it. That is true for me.
