John Tilbury quotes:

Experimental music scores are enigmatic, opaque, demanding, irritating, humorous, childlike; the best, like Cardew's Treatise, are also inspiring, giving rise, on occasion, to a music of vitality, intelligence and elegance.

If the nobles of the country really have the welfare of the people at heart, they should prevent and forbid music wherever it makes an appearance. For the fact that the people practise music has four disadvantages. The hungry are not fed, the cold are not clothed, the homeless are not sheltered and the desperate find no consolation.

It should be pointed out that none of Cardew's works ever gave total freedom to the performer. The instructions were a guide which focused each individual's creative instinct on a problem to be solved - how to interpret a particular system of notation using one's own musical background and attitudes.
