Sense and Sensibility (1995)

Continuity mistake: Toward the end of the film, Elinor is gardening and has dirt and mud all over her hands. Upon realising Edward is riding toward the house, she hurriedly wipes her hands on her apron, smearing a good amount of dirt on it. When she then removes the apron while standing inside the house, both the apron and her hands are barely dirty.

Elinor Dashwood: You have no confidence in me.
Marianne: This reproach from you. You who confide in no-one.
Elinor Dashwood: I have nothing to tell.
Marianne: Nor I. Neither of us have anything to tell. I because I conceal nothing and you because you communicate nothing.

Trivia: In the scene where Marianne, Eleanor, Lucy, and Mrs. Jennings enter Mrs. Jennings house in London for the second time, Marianne asks Pigeon if any letters had arrived, watch Lucy in the background, she is playing with the parrot on its perch and it tries to bite her.

Question: Very near the beginning, Marianne is playing this tune that she says was her father's favourite and Elanor tells her to stop. What is the tune and is it possible to find music for it? It's not the 'Weep You No More Sad Fountains' one.
