It seems afterwards to have occurred to Bertin that music as good as Rossini's might be composed by machinery. He declares, indeed, in a pamphlet directed against Rossini, entitled "La musique mechanique et de la musique philosophique," that he once asked Maelzel, the inventor of the metronome, whether he could construct a machine to compose music; upon which Maelzel daringly replied that he could, but that his mechanically-made tunes would not be up to the level of Sacchini, Cimarosa, and Mozart, and would be worthy only of Rossini. "M. Auber has told me," says M. Jouvin, in his Life of that composer, "how he met Rossini for the first time at a dinner given by Carafa in honour of his illustrious compatriot. On rising from table the maestro, at the request of his host, went to the piano and sang Figaro's cavatina, 'Largo al fattotum della cità.' "'I shall never forget,' said M. Auber to me, 'the effect produced by his lightning-like execution.' Rossini had a beautiful baritone voice, and he sang his music with a spirit and _verve_ which neither Pellegrini nor Galli nor Lablache approached in the same part. As for his art as an accompanist, it was marvellous; it was not on a key-board but on an orchestra that the vertiginous hands of the pianist seemed to gallop. When he had finished I looked mechanically at the ivory keys; I fancied I could see them smoking. On arriving home I felt much inclined to throw my scores into the fire. 'It will warm them, perhaps,' I said to myself; 'besides, what is the use of composing music, if one cannot compose like Rossini?'" Apart from a little professional jealousy, Rossini met in Paris with the warmest possible reception; and the men in authority gave him substantial marks of their esteem. He was appointed director of the Théâtre des Italiens, with a salary of 20,000 francs a year; and when after eighteen months' service he resigned this post, the salary was continued to him in connection with another, of which the duties were purely nominal: that of "Inspector of singing." In granting Rossini this salary, the object of the government was to induce him to remain in France, and to compose a series of works for the Académie where, after producing _Il Viaggio a Reims_, at the Italian Theatre in honour of Charles X.'s coronation, he brought out in succession _Le Siège de Corinthe_,[10] re-arranged from _Maometto Secundo_, an opera of the year 1820; _Moïse_, re-arranged from _Mosè in Egitto_, a Lenten opera oratorio of the year 1818; _Le Comte Ory_, re-arranged with many additions from _Il Viaggio a Reims_; and his greatest work _Guillaume Tell_.
