Computer-generated music is when a computer is used to create music instead of a person playing instruments or singing. It's kind of like a robot that makes music!
The computer uses special software that allows it to make different sounds and put them together in a way that sounds like music. The software has lots of different settings and options, so the computer can make all kinds of different sounds and rhythms.
Sometimes, people will program the computer to make music in a certain style, like classical or rock. Other times, the computer will be given a set of rules to follow, like "play this note twice as long as the last note" or "switch to a different sound every five seconds."
While computer-generated music can sound pretty cool, it's important to remember that it doesn't have the same emotional and creative depth as music made by humans. But it's still a fun and interesting way to make music!
