These three pieces from the French composer Michel Corrette come from the bundle 'Les Amusemens du Parnasse', Livre 1, 1749 (Paris). With the explanation (freely translated from French): A short and easy method to learn to play the harpsichord, with the prettiest tunes/airs which are in fashion.
I didn't exactly follow the exact rules of French baroque registration in the first piece, in case anyone wonders ;)
