After Lulli, the next great name in the history of French opera was that of Jean Philippe Rameau (1683-1765). This great master was one of the most versatile men of whom we have a record in music. He was a mathematician, physicist, a profound theorist, and a virtuoso upon the piano and harpsichord. He is one of the four great names in music of the period of Bach and Haendel, the fourth being Scarlatti. His education in music began while he was very young, and it is said of him that such was his talent that he could improvise a fugue upon any theme assigned, when he was but fourteen years of age. His father wished him to be trained for the law, but music had greater charms for him, and the margins of his books were marked over with crotchets and quavers. Having become desperately in love with a fascinating young widow, whom his father was opposed to his marrying, he was sent at the age of seventeen to Italy, ostensibly to study. He came, therefore, to Milan about 1701, a few years before Haendel came there. Italian music was little to his taste. The dignified declamation of the Lulli operas seemed to him better worthy the attention of men than the tunes of the Italians. Accordingly he took service as a violinist with a traveling operatic troupe, and in this capacity visited the south of France. In Paris he became a pupil of the court organist Marchand, of whom we hear again in connection with certain tests of proficiency with Haendel. Marchand was at first delighted with his new pupil, but presently dropped him when he discovered how talented he was, and liable to prove a dangerous rival. Accordingly he left Paris and took service as organist at Lille, which post he exchanged afterward for one at Clermont. In this quiet town he devoted himself to the study of harmony, and to reflection upon the principles of music. He read here the works of Zarlino, and other Italian theorists, and in 1721 he returned to Paris and published his treatise on harmony, in which he propounded the theory of inversions. His second treatise on harmony, "New System of Musical Theory," was published in 1725. These works excited a great deal of attention and brought the author renown, but his soul yearned for recognition as composer, and in 1730 he obtained from Voltaire a libretto, "Samson." This work was declined at the national opera, on the ground that the public was not attracted by Biblical subjects. Three years later, however, he composed another, "_Hypolite et Arcie_," which was performed with moderate success. He had now reached the age of fifty, and entered upon the second stage of his artistic career, and the second period of the French opera. The admirers of Rameau invited appreciation of the new works upon the ground of their being better than those of Lulli, and all Paris was divided into two opposite camps. Rameau is entitled to having developed his operas more musically than those of Lulli, and the later ones became still richer upon the orchestral side.
