In total, Bernstein composed two and a half hours of music for the film, writing for a full symphony orchestra augmented with various ethnic and unusual instruments such as the shofar, the tiple, and the theremin. The score is written in a highly Romantic style, featuring unique musical leitmotifs for the film's characters (God, Moses, Rameses, Nefretiri, etc.) used in a manner inspired, at DeMille's direction, by the opera scores of Richard Wagner. Bernstein recorded both the diegetic music and the score at the Paramount Studios Recording Stage in sessions spread from April 1955 to August 1956.
