Louis Couperin
Included are almost all known harpsichord pieces by Louis Couperin and Chambonnières, with more than 142 pieces by Chambonnières and more than 20 pieces by Johann Jakob Froberger and music by several other composers, including Joseph Chabanceau de La Barre, Jacques Hardel, Étienne Richard and Girolamo Frescobaldi. Most important of all the pieces are the 122 works by Louis Couperin, who was one of the most important European composers of the time and who never published any of his works; the Bauyn manuscript is a principal source for his harpsichord oeuvre.
