Yvonne dresses in white and strives to play a piece on the piano while her sister Christine contemplates the score in an accomplice way.

Although Renoir does not renounce capturing natural light and colour, he is particularly interested in the modelling and drawing of the figures, wrapped in an atmosphere that does not manage to dilute the contours like Claude Monet (1840–1926), the French painter and founder of Impressionism.

In this way, Renoir presents himself as a painter who gives joy and a certain romanticism to his compositions, achieving an important success before the public, as proof that this work was the first acquired by the French State.

An optimistic theme, much loved by bourgeois collectors, is portrayed: that of girls in a domestic atmosphere, playing games, reading or, as in this case, practicing music.

Renoir describes with great precision various details of the domestic environment in which the girls find themselves, focusing mainly on the two paintings hanging on the wall, in this case Before the Race and A Group of Dancers, both by Degas.
