Is playing the piano considered forbidden if it is not done in front of people and is done after fulfilling worldly and religious obligations?

Playing the piano is forbidden because it is one of the prohibited musical instruments. This prohibition includes playing alone or in front of people, the latter being more severely prohibited due to the open declaration of wrongdoing. Listening to music is also unanimously forbidden, with the exception of the daff (tambourine) for women during Eids and joyful occasions.
