François Couperin 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 acknowledged his debt to the Italian composer Corelli. He introduced Corelli's trio sonata form to France. Couperin's grand trio sonata was subtitled Le Parnasse, ou L'apothéose de Corelli ("Parnassus, or the Apotheosis of Corelli"). In it he blended the Italian and French styles of music in a set of pieces which he called Les goûts réunis ("Styles Reunited"). His most famous book, L'art de toucher le clavecin ("The Art of Harpsichord Playing", published in 1716), contains suggestions for fingerings, touch, ornamentation and other features of keyboard technique.
