"Treating each film as an 'opera without singing' (each character has his or her own leitmotif) Korngold created intensely romantic, richly melodic and contrapuntally intricate scores, the best of which are a cinematic paradigm for the tone poems of Richard Strauss and Franz Liszt. He intended that, when divorced from the moving image, these scores could stand alone in the concert hall. His style exerted a profound influence on modern film music."
