A motif is a repeating element in a tale that is not always the primary message. While the motif is concerned with the core message of a tale, it is a recurrent aspect. For example, in The Three Little Pigs, the wolf's role as a villain is emphasized through his use as a motif. In addition to being evil, he is also depicted as crafty. On the other hand, a theme is a central idea that runs through a work of art or literature. It may be explicit or implicit and can be used to characterize characters or events. A theme can also be called a leitmotif if it comes up again and again throughout the work. The three little pigs story has a clear theme which is "that wisdom is better than strength". In music, a motif is a short musical phrase or fragment that often functions as a theme for a larger section or piece. It is something that is repeated at some point in the larger composition to indicate recognition or importance. For example, the opening notes of Beethoven's Fifth Symphony are a familiar motif that appears later in the work when describing the beginning of his Fifth Symphony. The word "motif" was first used by German composer Johann Sebastian Bach to describe a short musical idea that recurs in his compositions.
