Gaspard Le Roux (c. 1670 – c. August 1706) was a French harpsichordist active in Paris at the beginning of the 18th century.
A Le Roux is mentioned as the contributor of an air spirituel in Mercure galant (March 1690), but whether this refers to Gaspard in unclear.
[A previously discovered reference by French musicologist Pierre Hardouin[4] that claimed the receipt of an inventory of Le Roux's chattels on 7 June 1707 has been proved incorrect.
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 (1701) at the French end, Elizabeth Jacquet de la Guerre's second book (1707) 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.
