In its most simplest form, a mashup is a combining of two or more songs, the instrumental of one with the a capella of another, to make a new song. That is a pretty basic understanding of what a mashup can be.
There are all kinds of technical definitions and forms of a mashup, but overall, creating a fun and interesting one is taking two seemingly unrelated musical ideas and blending them together into something that is in it’s own right a new musical experience.
A mashup or blend (also mash up and mash-up) is a song or composition created by blending two or more songs, usually by overlaying the vocal track of one song seamlessly over the music track of another. To the extent that such works are ‘transformative‘ of original content, they may find protection from copyright claims under the “fair use” doctrine of copyright law.
