The document discusses three elements of intertextuality: parody, pastiche, and homage. Parody involves changing or copying existing musical ideas, lyrics, or an artist's style to imitate and comment on the original work in a humorous way. Pastiche imitates another artist's style as well, but does so more respectfully without mocking the original. Homage takes inspiration from another work in a respectful manner without directly copying or mocking the source of inspiration. Examples of each are provided.
