ELI5: Explain Like I'm 5

Polymodal chromaticism

Polymodal chromaticism is like playing with different colors of music. Just like how you can color a picture with many different colors, musicians can play different kinds of music together at the same time. Polymodal chromaticism is when musicians combine different musical scales that have different melodies and sounds. It's like when you mix a pink and blue crayon to make purple. The musicians mix different melodies to make a new and unique sound. It might sound a bit complicated, but it's just like creating a beautiful painting with different colors!
