text: Operatic reforms Gluck had long pondered the fundamental problem of form and content in opera. He thought both of the main Italian operatic genres, opera buffa and opera seria, had strayed too far from what opera should really be and seemed unnatural. Opera buffa had long lost its original freshness. Its jokes were threadbare and the repetition of the same characters made them seem no more than stereotypes. In opera seria, the singing was devoted to superficial effects and the content was uninteresting and fossilised. As in opera buffa, the singers were effectively absolute masters of the stage and the music, decorating the vocal lines so floridly that audiences could no longer recognise the original melody. Gluck wanted to return opera to its origins, focusing on human drama and passions and making words and music of equal importance.
  Francesco Algarotti's Essay on the Opera (1755) proved to be an inspiration for Gluck's reforms. He advocated that opera seria had to return to basics and that all the various elements—music (both instrumental and vocal), ballet, and staging—must be subservient to the overriding drama. Several composers of the period, including Niccolò Jommelli and Tommaso Traetta, attempted to put these ideals into practice (and added more ballets).
  In Vienna, Gluck met like-minded figures in the operatic world: Count Giacomo Durazzo, the head of the court theatre, and one of the primary instigators of operatic reform in Vienna ; the librettist Ranieri de' Calzabigi, who wanted to attack the dominance of Metastasian opera seria; the innovative choreographer Gasparo Angiolini; and the London-trained castrato Gaetano Guadagni.
