Free improvisation, in addition to being a highly skilled musical craft, is open to use by almost anyone-beginners, children, and non-musicians. The skill and intellect required is whatever is available. Its accessibility to the performer is, in fact, something which appears to offend both its supporters and detractors....And as regards method, the improvisor employs the oldest in music-making...Mankind's first musical performance couldn't have been anything other than a free improvisation.
Derek BaileyPersonally, I've found one of the more stimulating ways of playing in recent times has been to kind of move outside the free improvised area and work with people who are probably improvisers but they have a particular way of working.
Derek BaileyUndeniably, the audience for improvisation, good or bad, active or passive, sympathetic or hostile, has a power that no other audience has. It can affect the creation of that which is being witnessed. And perhaps because of that possibility the audience for improvisation has a degree of intimacy with the music that is not achieved in any other situation.
