The Bauyn manuscript has been described as one of the most important sources for French harpsichord music of the 17th century. It is currently held in the Bibliothèque Nationale de France, in Paris. In this book are almost all known harpsichord pieces by Louis Couperin and Chambonnières, 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. The name of the manuscript comes from the Bauyn d'Angervilliers family, who once possesed it. The pieces in it are according to their genre, not in suites; some are also organized by key.
