derivative works

A derivative work is a new creation based on an existing copyrighted work, such as a translation, adaptation, or remix. It transforms or builds upon the original, like turning a novel into a screenplay or modifying a song. To create or distribute a derivative work legally, you typically need permission from the original rights holder, because it involves using someone else's protected material as a foundation. Think of it as a new version or interpretation that changes or adds to the original work, while still depending on its core elements.
