Makrokosmos Volume I, whose title reflects Crumb’s admiration for Bartók’s piano series Mikrokosmos, contains 12 pieces, grouped into three parts of four each, and Crumb associates each piece with a sign of the zodiac. This is paired with Volume II, which is similarly structured, after the fashion of Debussy’s twenty-four Préludes. Volumes I and II are filled with references to the history of humankind, myths, Christianity, paganism, occultism, literary works, and the composer’s own mental pictures. They are constellations that adorn the infinite universe – Makrokosmos.
