Remixing is when you take a piece of music and change it so it sounds different. Sometimes people make remixes of songs they like and add their own flavor to it. For example, you might take somebody else's song and add some beats or bass or other instruments to make it sound different. You can also remix other versions of the same song to give it a new twist. Remixing can be fun and creative, and it's a great way to put your own mark on a song.
