Kreutzer’s compositions, independently of those for the stage (which exceed thirty in number), consist of two “sinfonie concertanti” for two violins—one sinfonia for violin and violoncello concertante—upwards of fifty concertos, duetts, trios and quartetts—five sets of sonatas for violin and bass—eight sets of studios and capriccios—and several airs with variations. The compilation of the _Violin-system_ for the Conservatory was also in part effected by him. CHARLES PHILIPPE LAFONT, one of the most excellent of recently living violinists, was born at Paris, where the beauties of his execution long continued to draw numerous audiences to the concerts he was in the habit of giving. His first lessons in the art were received from his uncle, Bertheaume. After having, successively, Berton, and Navoigille the elder, as masters in composition, and acquiring, by unaided study, a knowledge of singing, he travelled with his uncle, who procured him occasions for exhibiting his various powers in the principal cities of Europe. Returning to France in 1794, he first appeared at Paris as a vocalist; but was _most_ admired as a _violin performer_, in which character he shone at the Opera concerts, and the _Salle Olympique_. He completed his studies under Kreutzer and Rode—to the latter of whom, in the sweet qualities of his style, he mainly inclined. His next journey was to Petersburg, where he resided several years, as the Emperor’s First Violin. In 1805 or 1806, he returned to his native city; and was appointed leader at the King’s Chapel. A suavity and elegance, especially in _cantabile_ movements—a tasteful selection of ornament—and an exemplary purity of tone—have been remarked as denoting this artist. The scene in his career which exhibits him in an indiscreet rivalry with Paganini, will be found under the memoir given of that extraordinary person. PIERRE BAILLOT, of high name in the French School, which he was partly enabled to acquire through Italian instruction, was born about the year 1770, near Paris, to which city the curious in coincidences will be delighted to find that they can trace the local origin of so many of those eminent violinists who have made it, also, the scene of their brilliant exertions. Baillot repaired early to Rome, where he remained some years under the tuition of Polani, an excellent Professor of the school of Tartini. His own feeling and intellect appear to have done more for his advancement, however, than the lessons of preceptors. An artist of a very high order, well versed in the mechanical resources of his instrument, he was also thoroughly embued with musical sentiment, and was a discriminating judge in matters of composition.
