Nicolas Lebègue is remembered as one of the most erudite composers of the late seventeenth century. He was the organist at Saint-Merry in Paris and known as the teacher of Nicolas de Grigny and François D’Agincourt, among others. Apart from his three books of organ music (1676, 1678 and 1685), he also published two collections of pieces for the harpsichord in 1677 and 1687. This series draws together Lebègue’s keyboard music in three volumes from printed and manuscript sources. The first contains the two harpsichord books and the only known manuscript; the second volume includes the printed organ books; the third acts as an appendix to Volume II and presents pieces attributed to Lebègue from two known sources, Le Manuscrit Caumont Orgue and a manuscript in the Bibliothèque nationale de France, copied by Sébastien de Brossard between 1688 and 1698.
