The music in the play Therese Raquin was limited but had an important role. The music was mostly played as a transition between different scenes. The music was also played when something went wrong. The dominant tone of the music was ominous and was essential in creating the gloomy atmosphere of the novel. The only positive tone music was played during times of marriage and when Therese was singing out of happiness. The music was also synced with the lights. As the lights went out, the music began playing indicating a moment of transition. The background music of hummingbirds was also noticeable throughout the play. The idea that Therese created the most positive music is significant because it shows that the overall environment of the novel is not fit for happiness and positivity. The music of the play helped set the setting of the novel in the play.
