The next great assistance to the French Opera, and this a permanent one, was given by the Republic, through the establishment of a large music-school, known as the Conservatoire, where a course of gratuitous instruction is given to all comers capable at the stipulated age of passing the indispensable test examination. Before, however, the Conservatoire, destined to produce so many excellent vocalists, instrumentalists, and composers, had time to bear fruit, Napoleon had done much to encourage and develop French musical art. Napoleon, as a young man, was one of the first admirers of the afterwards famous Mme. St. Huberti; and when Mme. Mara refused an engagement pressed upon her at the time of the Empire, Napoleon would have arrested her and forced her to accept it had she not fled from Paris. Then, another cause of improvement at the French Opera was the frequent visits paid, early in this century, and especially since the Peace of 1815, by foreign artists to the capital which, in former days, had set its face both against vocalists and composers from abroad. Lulli, the founder of opera in France, was an Italian by birth, though after his naturalisation he got to be looked upon as a Frenchman. His successor, Rameau, was no doubt a Frenchman. But the French tradition was so completely broken by the advent of Gluck and Piccini that the French have never since exhibited any of their ancient prejudice against foreign composers; and it is to these that for the last seventy or eighty years the Grand Opera of Paris has owed most of its success, that is to say, to Spontini, Rossini, Donizetti, Verdi, and, above all, Meyerbeer.
