Both La Sylphide and Giselle appeal to the audiences of their time being romantic and imaginative. They both followed a love story that ended with the woman dying and the man mourning. In the first act, both ballets show the town as being normal, while the second act is more dreamlike and sad. However the Sylphs in La Sylphide are not as sinister as the Willis in Giselle and seem to serve different purposes in the imaginary act. These differences are contributed to by the differing music and lighting of both plays. In the second act of Giselle, the stage is dark and gloomy and the music is sadder while the lighting and music in act two of La Sylphide is lighter. There are many basic similarities in the story and ideas of both ballets.
