Late 18th century (time of the French Revolution): the composers-organists had to manage at best to live this environment.
Some pieces are very interesting but they must absolutely be played on an instrument of the time (like the organ of "Vitry Le François" that I played every day during six months during a stay in metropolitan France).

Since I love this music. The Hauptwerk Forcalquier organ looks a little like this and allows you to play this music at home.
To make Beauvarlet-Charpentier better known, I only select the pieces that I think are better.
