ELI5: Explain Like I'm 5

Music written in all major and/or minor keys

Okay kiddo, let me explain it like you're five! Imagine you have a bunch of different colored crayons - some are red, blue, green, yellow, and many more. Now, imagine that these colors represent different "feelings" in music. When musicians write songs, they can choose to use certain colors or "feelings" of music to create different moods or emotions.

Major and minor keys are like the different colors of crayons. Just like how you might use a blue crayon to draw a sad picture and a yellow crayon to draw a happy picture, musicians might use major or minor keys to make their music sound a certain way.

Major keys sound bright and happy - like sunshine on a beautiful day! They make you feel happy and excited. Minor keys, on the other hand, sound sad and dramatic - like a stormy day or a scary movie. They make you feel nervous or sad.

When musicians write music, they can choose to use any of the major or minor keys to create different emotions in their songs. They might use a major key to make a happy song or a minor key to make a sad song.

Overall, major and minor keys are just different "colors" or "feelings" of music that musicians can choose to use to make their songs sound a certain way.
