François Couperin (French: [fʁɑ̃swa kupʁɛ̃]; 10 November 1668 – 11 September 1733) was a French Baroque composer, organist and harpsichordist. He was known as Couperin le Grand ("Couperin the Great") to distinguish him from other members of the musically talented Couperin family.
Couperin was born into one of the best known musical families of Europe. His father Charles was organist at Church Saint-Gervais in Paris, a position previously occupied by Charles' brother Louis Couperin, a highly regarded keyboard virtuoso and composer whose career was cut short by an early death. As a boy, François must have received his first music lessons from his father. Unfortunately, Charles died in 1679. The church council at Saint-Gervais hired Michel Richard Delalande to serve as new organist, with the condition that François would replace him at age 18. Meanwhile, the boy was taken care of and taught by organist Jacques-Denis Thomelin, who served both at the court and at the famous church of St Jacques-de-la-Boucherie. According to a biography by Évrard Titon du Tillet, Thomelin treated the boy extremely well and became "a second father" to him. François's talent must have manifested itself quite early, since already by 1685 the church council agreed to provide him with a regular salary even though he had no formal contract.
Couperin's mother Marie (née Guérin) died in 1690, but otherwise his life and career were accompanied by good fortune. In 1689 he married one Marie-Anne Ansault, daughter of a prosperous well-connected family. The next year saw the publication of Couperin's Pieces d'orgue, a collection of organ masses that was praised by Delalande (who may have assisted with both composition and publication). In three more years Couperin succeeded his former teacher Thomelin at the court. The new appointment was extremely prestigious and brought Couperin in contact with some of the finest composers of his time, as well as numerous members of the aristocracy. His earliest chamber music dates from around that time. The numerous duties Couperin carried out at the court were accompanied by duties as organist at Saint Gervais, and also by the composition and publication of new music. He obtained a 20-year royal privilege to publish in 1713 and used it immediately to issue the first volume (out of four) of his harpsichord works, Pieces de clavecin. A harpsichord playing manual followed in 1716, as well as other collections of keyboard and chamber music. In 1717 Couperin succeeded one of his most eminent colleagues, Jean-Baptiste-Henry d'Anglebert, as ordinaire de la musique de la chambre du roi pour le clavecin, one of the highest possible appointments for a court musician. However, his involvement in the musical activities at the court may have lessened after Louis XIV's death in 1715.
