Kyrie from Messe Solemnelle

Couperin was born in Paris, into a prominent musical family.[2] His father Charles was organist at the Church of Saint-Gervais in the city, a position previously held by Charles's brother Louis Couperin, the esteemed 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, but Charles died in 1679 leaving the position at Saint-Gervais to his son, a common practice known as survivance that few churches ignored. With their hands tied, the churchwardens at Saint-Gervais hired Michel Richard Delalande to serve as new organist on the understanding that François would replace him at age 18. However, it is likely Couperin began these duties much earlier: a stipend of 100 livres per year, which had been provided the Couperin on Charles's death slowly increased to 400 livres, suggesting that Couperin had gradually begun to take on the mantle as his studies progressed.

The 11-year-old was taken care of and taught, meanwhile, by organist Jacques-Denis Thomelin, who served both at court and at the church of Saint-Jacques-de-la-Boucherie. Biographer Évrard Titon du Tillet wrote that Thomelin treated the boy extremely well, becoming a second father to him. François' talent must have shown itself early on because by 1685 the church council began providing him a salary, although he had no contract.
