We have seen that Paisiello, some years after his return to Italy, was engaged by Napoleon as chapel-master, and that the services of Paer were soon afterwards claimed and secured by the emperor as composer of his chamber music. This was not the first time that Paer had been forced to alter his own private arrangements in consequence of the very despotic patronage accorded to music by the victorious leaders of the French army. In 1799 he was at Udine, where his wife was engaged as _prima donna_. Portogallo's _la Donna di genio volubile_ was about to be represented before a large number of the officers under the command of Bernadotte, when suddenly it appeared impossible to continue the performance owing to the very determined indisposition of the _primo basso_. This gentleman had gone to bed in the middle of the day disguised as an invalid. He declared himself seriously unwell in the afternoon, and in the evening sent a message to the theatre to excuse himself from appearing in Portogallo's opera. Paer and his wife understood what this meant. The performance was for Madame Paer's benefit; and Olivieri, the perfidious basso, from private pique, had determined, if possible, to prevent it taking place. Paer's spirit was roused by the attitude of the _primo buffo_, which was still that of a man confined to his bed; and he resolved to frustrate his infamous scheme, which, though simple, appeared certain of success, inasmuch as no other comic _basso_ was to be found anywhere near Udine. The audience was impatient, Madame Paer in tears, the manager in despair, when Paer desired that the performance might begin; saying, that Providence would send them a basso who would at least know his part, and that in any case Madame Paer must get ready for the first scene. Madame Paer obeyed the marital injunction, but in a state of great trepidation; for she had no confidence in the capabilities of the promised basso, and was not by any means sure that he even existed. The curtain was about to rise, when the singer who was to have fallen from the clouds walked quietly on to the stage, perfectly dressed for the part he was about to undertake, and without any sign of hesitation on his countenance. The _prima donna_ uttered a cry of surprise, burst into a fit of laughter, and then rushed weeping into the arms of her husband,--for it was Paer himself who had undertaken to replace the treacherous Olivieri. "No," said Madame Paer; "this is impossible! It shall never be said that I allowed you, a great composer, who will one day be known throughout Europe, to act the buffoon. No! the performance must be stopped!"
