The title of this work is intentionally ambiguous: on one hand, the term comes from a word meaning "many", and which alludes to all of the instruments used by the six percussionists along the four movements; on the other hand, it refers to a myth in Greek mythology: the Pleiades are the seven daughters of Pleione and Atlas even though the greatest part of his inspiration may come from the astronomy, as the Pleiades were thought to be the stars from Taurus.
