It is 49 measures long and begins with a driving ostinato in the strings that is answered by agitated woodwinds and brass. This builds to a powerful and dramatic climax, followed by a solemn, mysterious introduction to the main theme. After this introduction, the strings continue with a passionate, lyrical melody – an ode to the characters and story of the opera. The piece ends with a triumphant finale, featuring intense fortissimo chords, powerful cymbals and trombones. The overall effect of this piece is one of tremendous energy and excitement, setting the tone and atmosphere for the opera to come.
