“With clarity of rhythmic structure, grace forms a duality. Together they have a relation like that of body and soul. Clarity is cold, mathmatical, inhuman, but basic and earthy. Grace is warm, incalculable, human, opposed to clarity, and like the air. Grace is not here used to mean prettiness; it is used to mean the play with and against the clarity of the rhythmic structure. The two are always present together in the best works of the time arts, endlessly, and life-givingly, opposed to each other.” – John Cage Silence- lectures & writings
