Task: Question Generation
Input (English): Passage: Discounting his collaboration with Dukas in the completion of Guiraud's unfinished Frédégonde, Saint-Saëns wrote twelve operas, two of which are opéras comiques. During the composer's lifetime his Henry VIII became a repertory piece; since his death only Samson et Dalila has been regularly staged, although according to Schonberg, Ascanio (1890) is considered by experts to be a much finer work. The critic Ronald Crichton writes that for all his experience and musical skill, Saint-Saëns "lacked the 'nose' of the theatre animal granted, for example, to Massenet who in other forms of music was his inferior". In a 2005 study, the musical scholar Steven Huebner contrasts the two composers: "Saint-Saëns obviously had no time for Massenet's histrionics". Saint-Saëns's biographer James Harding comments that it is regrettable that the composer did not attempt more works of a light-hearted nature, on the lines of La princesse jaune, which Harding describes as like Sullivan "with a light French touch".Although most of Saint-Saëns's operas have remained neglected, Crichton rates them as important in the history of French opera, as "a bridge between Meyerbeer and the serious French operas of the early 1890s". In his view, the operatic scores of Saint-Saëns have, in general, the strengths and weaknesses of the rest of his music – "lucid Mozartian transparency, greater care for form than for content ... There is a certain emotional dryness; invention is sometimes thin, but the workmanship is impeccable." Stylistically, Saint-Saëns drew on a range of models. From Meyerbeer he drew the effective use of the chorus in the action of a piece; for Henry VIII he included Tudor music he had researched in London; in La princesse jaune he used an oriental pentatonic scale; from Wagner he derived the use of leitmotifs, which, like Massenet, he used sparingly. Huebner observes that Saint-Saëns was more conventional than Massenet so far as through composition is concerned, more often favouring discrete arias and ensembles, with less variety of tempo within individual numbers. In a survey of recorded opera Alan Blyth writes that Saint-Saëns "certainly learned much from Handel, Gluck, Berlioz, the Verdi of Aida, and Wagner, but from these excellent models he forged his own style.".
