Scarlatti was a rover. He tried his fortune in Italy, in England, in Portugal and Spain. He won it by the exhibition of his extraordinary and startling powers. He was on the alert to startle, his tribute the bravas and mad applause of his excited hearers. He was the virtuoso in an old sense of the word, the man with his powers consciously developed to the uttermost. Bach, on the other hand, was an introspective, mighty man, immeasurably greater than his surroundings, fathomless, personal, suggestive. Between them stands Couperin, for the greater part of his life in the intimate service of the most brilliant court the world has ever seen, delicate in health, perfect in etiquette, wise and tender. Of his life little need be said. He was born in Paris on November 10, 1668, the son of Charles Couperin, himself a musician and brother to Louis and François Couperin, disciples of the great Chambonnières. The father died about a year after his son was born, and the musical education of the young François seems to have been undertaken by his uncle, François, and later by Jacques Thomelin, organist in the king’s private chapel in Versailles. Practically nothing is known of his youth, and, though it is certain that he was for many years organist at the church of St. Gervais in Paris, as his uncle and even his grandfather had been before him, the time at which he took up his duties there has not been exactly determined. There is on record, however, the account of a meeting held on the twenty-sixth of December, 1693, at Versailles, at which Louis XIV heard Couperin play and chose him from other competitors to succeed Thomelin as his private organist. Thenceforth he passed his life in service of the king and later of the regent. He died in Paris in 1733, after several years of ill health. The great François was, no doubt, an unusually skillful organist, but his fame rests upon his work for the clavecin, the French harpsichord, and his book of instruction for that instrument. His duties at court were various. He says himself that for twenty years he had the honor to be with the king, and to teach, almost at the same time, Monseigneur le Dauphin, the Duke of Burgundy, and six princes or princesses of the royal house. In his preface to the _Concerts royaux_ he informs us that chamber concerts were given in the king’s presence on Sunday afternoons at Versailles, and that he was commanded to write music for them and that he himself played the clavecin at them. His book on the art of playing the clavecin, written in 1716, was dedicated to the king. By all accounts he was a beloved and highly prized teacher and performer. And neither his pupils nor his fame were confined solely to the court.
