 In historicist modernism, "musical techniques from the remote past are used prominently and vigorously as a way of achieving a distance from late Romantic styles" .Whereas the historicism of the "Ancient Airs and Dances for Lute" (1917–31) by Ottorino Respighi is readily apparent to the ear, since the composer drew directly on the works of 16th- and 17th-century composers, the historicism informing the "Music of Changes" (1951) by John Cage, based on the ancient Chinese I Ching, is deeply embedded in the compositional process .Many physicists, including Einstein, have maintained that the familiar division of time into past, present, and future is an illusion, from which it necessarily follows that "old" and "new" are terms as relative as "up" and "down" .
