Okay kiddo, so you know how there are different colors like blue, red, and green? Well, in music there are different scales which are kind of like colors for sounds.
The blues scale is a special scale that is used a lot in blues music. It’s like a special set of notes that make a certain sound that sounds sad or “blue”.
If you want to play the blues scale, you would start on a certain note, and then play a pattern of notes that go up and down. The notes in the blues scale are different from the notes in a regular scale, and that’s what gives it its special sound.
So, imagine you are playing with three toy cars. One is a blue car, one is a red car, and one is a green car. The blue car is like the blues scale because it’s a special car that you use when you want to play a game that needs a blue car. Just like how you use the blues scale when you want to make music that sounds sad or “blue”.
