One of my favorite artists is Johannes Vermeer, who painted this oil on canvas titled: Lady at the Virginal with a Gentleman, 'The Music Lesson'" sometime between 1662 and 1665. One might think that baroque musicians would be poor, but in fact it was quite the contrary. Musical instruments were often a symbol of the wealthy and elite. This painting shows a static viola da gamba lying on the floor while the young woman is practicing a virginal under the tutelage of the male teacher.
Vermeer often used natural light, generally from a window on the left, to light his scenes. The subjects and the musical instruments are evenly lit, with very little contrast. The architecture uses many straight lines and repetitious patterns - square window panes, diagonal tiles on the floor and straight overhead beams. This use of contrast helps to highlight the human forms. The painting on the upper right and the tapestry covering the table give the scene balance by filling in the negative space.
It is interesting to note that the mirror shows the woman looking toward the man endearingly. If you zoom in, you can see the artist's easel. In this way, the artist is a subtle part of the scene.
