Elizabeth Bennett (Pride and Prejudice) was invited by Georgina and Darcy to Pemberly for dinner.  There, Elizabeth and Georgina took turns in playing the piano and singing.  A woman of the upper class must have thorough knowledge of music (which includes playing the piano) singing, drawing, dancing and the modern languages.  Jane Austen herself played the piano.  In the late 18th-19th century, the piano was the means by which a woman provide songs and entertainment for the family.  Women make frequent trips to the post office to check on the arrival of the latest piece of music journal or periodicals.
