During the evening banquet on the second day, there are fireworks. The music played and sung (heard) is 'Music for the Royal Fireworks'. G. F. Handel composed this piece in 1749. The movie is set in 1671. It had not been composed by that time.
At the start of the garden feast, the music begins with a brief woodwind duet. Though the two musicians play oboes, the oboes make the sound of recorders.
