Recurring musical themes, also known as MOTIFS, are short musical phrases that are repeated throughout a piece of music. They are often used to create a sense of unity and to help the listener recognize the piece. MOTIFS can be used to represent characters, emotions, or ideas, and they can be used to create tension or to provide a sense of resolution. MOTIFS can be used in any genre of music, from classical to pop, and they are an important part of musical composition.
