In a note to the conductor Serge Koussevitzky in February 1914, Stravinsky described The Rite of Spring as "a musical-choreographic work, [representing] pagan Russia ... unified by a single idea: the mystery and great surge of the creative power of Spring". In his analysis of The Rite, Pieter van den Toorn writes that the work lacks a specific plot or narrative, and should be considered as a succession of choreographed episodes.
