An old fool, in out-moded dress, masquerades as the music teacher of a prim young Miss seated at a harpsichord. The interior is well-to-do, as demonstrated by the richly carved doorway, gilt-framed painting, musical instrument, and beautifully rendered silks of the young lady’s costume. The large key hanging at the centre of the picture stands as an intentional ‘key’ to the interpretation of the scene. It is placed strategically on a line above the hand of the old man as it hovers above those of the young girl, implying the old man’s desire. The girl epitomizes the beautiful, but emotionally reserved woman, distinguished by her accomplishments, especially her musical ability. Not only is there a difference of age between the protagonists of the drama, but also a huge social gulf, which makes the old man’s passion appear all the more presumptuous.
