Relative minor

Okay kiddo, you know how sometimes you listen to a song that sounds really happy and upbeat, but then other times you hear a song that sounds kind of sad and slow? Well, in music, those happy songs usually have what's called a "major" key, and the sad songs have a "minor" key.

Now, here comes the trickier part. Sometimes, a song might start off in one key (let's say major), but then it changes to a different key that sounds kind of sad (minor). That new key is called the "relative minor."

Basically, the relative minor is a musical trick that lets the composer or songwriter change up the mood of a song without making it sound too abrupt or weird. It's like having two keys that are kind of related to each other and can be used interchangeably.

So, to sum it up, the relative minor is like a secret sad key that can be used to change the mood of a song, but it still sounds right because it's related to the happy key it came from.
