Antonio Salieri (1750-1825) with _Les Danaïdes_, in 1781, achieved a notable success in frank imitation of Gluck’s manner; indeed, the work, originally intrusted to Gluck by the Académie de Musique, was, with doubtful strategy, brought out as that master’s work, and in consequence brought Salieri fame and fortune. Other facts in Salieri’s life seem to bear out similar imperfections of character. He was, however, a musician of high artistic principles. When in 1787 _Tarare_ was produced in Paris it met with an overwhelming success, but Salieri nevertheless withdrew it after a time and partially rewrote it for its Vienna production, under the title of _Axur, Rè d’Ormus_. ‘There have been many instances in which an artist has been taught by failure that second thoughts are best; there are not many in which he has learned the lesson from popular approbation.’[17] Salieri’s career is synchronous with Mozart’s, whom he outlived, and against whom he intrigued in ungenerous manner at the Viennese court, where he became kapellmeister in 1788. He profited by his rival’s example, moreover, but his music ‘falls between the methods of his two great contemporaries, it is less dramatic than Gluck’s and it has less melodic genuineness than Mozart’s.’ Prominent among those who adhered to Italian operatic tradition was Giuseppe Sarti (1729-1802), ‘a composer of real invention, and a brilliant and audacious master of the orchestra.’ We have W. H. Hadow’s authority for the assertion that he first used devices which are usually credited to Berlioz and Wagner, such as the use of muted trumpets and clarinets and certain experiments in the combination of instrumental colors. Sarti achieved truly international renown; from 1755 to 1775 he was at the court of Copenhagen, where he produced twenty Italian operas, and four Danish singspiele; next he was director of the girls’ conservatory in Venice and till 1784 musical director of Milan cathedral,[18] and from 1784 till 1787 he served Catherine II of Russia as court conductor. His famous opera, _Armida e Rinaldo_, he produced while in this post (1785), as well as a number of other works. In 1793 he founded a ‘musical academy’ which was the forerunner of the great St. Petersburg conservatory, and he was its director till 1801. His introduction of the ‘St. Petersburg pitch’ (436 vibrations for A) is but one detail of his many-sided influence.
