In the search for new techniques and ’expanding the boundaries’ often composers can become so wrapped up in technique that the music as an art form is lost. Here is a composer whose vision has been to create a new form of composition (which he simply calls "non-prescriptive") in which the performer has varying degrees of freedom to manipulate choice around a set core. Related to other techniques of course, it remains a new and distinct method which can allow, even within the least ’set’ pieces, the music to remain approachable, often very beautiful and expressive. "Set" has twelve sections, and the degree of non-prescription increases as each piece follows.
