What must copying relate to in order to constitute infringement?

• A. The entire original work.
• B. Only the melody.
• C. Only the lyrics.
• D. A substantial part of the original work.

Answer: (D)

Infringement hinges on copying protectable expression to a substantial extent. It’s not enough to copy ideas or merely incidental elements; what matters is whether the material copied relates to a substantial part of the original work. A substantial part can be a distinctive melody hook, a chorus, a key lyric line, or an arrangement that carries the work’s essential character. If the copied portion is trivial or non-protectable, it usually won’t infringe; but when the portion copied is substantial and protectable, infringement can occur. So the standard looks at copying that relates to a substantial part of the original work.
