L'art de toucher le clavecin

L'art de toucher le clavecin (English: The Art of Playing the Harpsichord) is a didactic treatise by the French composer François Couperin. It was first published in 1716, and was followed by a revised edition in 1717.

The treatise was written to instruct keyboard players in performance practice, particularly for Couperin's Pièces de Clavecin; Couperin, upon its publication, noted that it was "absolutely indispensable for playing my Pièces in the style most suitable to them". With the early music revival, it became one of the primary sources for the keyboard fingering system which prevailed in Europe during the Baroque era. It also sheds light on the ornamentation used at the time. It is considered one of the most significant surviving treatises of the period.
