Gaspard Le Roux was a French harpsichordist active in Parisat the beginning of the 18th century. Little is known of his life, which is exacerbated by the commonality of his name among musicians and dance instructors in Paris. A Le Roux is mentioned as the contributor of an air spirituel in Mercure galant, but whether this refers to Gaspard in unclear. The name is also found in Nicolas de Blégny's Le Livre commode contenant les adresses de la ville de Paris … pour l’année 1692, although no address is included; in a tax document, Rolle des sommes qui seront payées par les Organistes et Professeurs de Clavecin de la Ville et fauxbourgs; two records of Gaspard Le Roux receiving annuities through the notaire publique Alexandre Lebèvre are dated 8 May 1702 and 5 August 1706 ; and the record of his being granted a Privilège du Roy dated 9 April 1705. Le Roux is known only for his 1705 publication, Pieces de Clavessin, that are arranged into seven 'suites'. These were engraved by Henry de Baussen and sold chez auteur, meaning Le Roux was responsible for not only the costs of engraving and printing, but also in securing the correct accreditation from the state. It was sold from the shop of Henry Foucault – "a L'entrée de la rüe Saint honnoré A la Regle D'Or" and costtenFrench livre 'en blanc' and eleven livres, ten sous in bound format. With the exception of the preludes and three dances, there are also found arrangements and five examples of realised contreparties, which arrange the second and bass lines of the trios as their starting points. The book suggests that Le Roux was a natural teacher, giving practical advice such as to sing the melodies and accompany them using the trios' thoroughbasses before playing them; it is also demonstrational, providing differing examples of dances and styles. If one imagines a spectrum, with Charles Dieupart at the French end, Elizabeth Jacquet de la Guerre's second book in the middle, and François Couperin in his most Italianate moments at the Italian end, Le Roux's style falls slightly to the French side of Jacquet.
