Boieldieu’s prospects now changed with Aladdin-like suddenness, for his next opera, “La Famille Suisse,” was performed at the Theatre Feydeau for thirty nights in alternation with Cherubini’s “Medee,” and thus early began that connection with the great Italian maestro, at that time the best musician in France, which was to be so fruitful of good results to the new favorite. In 1798 Boieldieu turned for a while from operatic work, and composed a number of piano sonatas, piano and harp duets, and a piano concerto. Although these exercised no permanent influence on the art, they obtained for him the appointment of professor of piano at the Paris Conservatoire, two years later. In this position, however he was not very successful; he was too much wrapped up in composition to make a good teacher. The musical historian Fétis, who was his pupil, confirms this estimate; but the post at the Conservatoire led to a close acquaintance with Cherubini, by which Boieldieu began to remedy his lack of knowledge of counterpoint and fugal work. Although Fétis denies that Boieldieu was ever the pupil of Cherubini, there is every reason to believe that this was the case, even if a regular stipend was not paid for the tuition. The very fact that in 1799 the two worked in collaboration on “La Prisonnière” might tend to show that Boieldieu was anxious to attain something of Cherubini’s musical learning, and his submission of many later operas to the judgment of this master proves that he was willing to be guided by him. About this time Boieldieu produced two operas that carried his fame beyond his native country; these were the Polish “Benjowski” and the very tuneful “Caliph of Bagdad,” both of which will receive further mention in the analytical portion of this article. A little later there appeared a more advanced work,—“Ma Tante Aurore.” The success was now so well established that all Parisian managers sought for works from the gifted pen, and opera followed opera.
