Okay kiddo, so you know how when you color or draw, you usually have a picture or an idea in your head of what you want it to look like? Well, free improvisation in music is kinda like coloring or drawing without having any rules or specific picture in mind.
Think of it like this: when musicians free improvise, they don't have a specific melody or rhythm that they're trying to play. Instead, they just start playing whatever comes to their minds in the moment, like doodling on a piece of paper without any guidelines.
Free improvisation is all about being creative and expressing yourself without any limitations or guidelines. It's like a musical playground where you can experiment with different sounds and ideas to see what feels and sounds good!
Just like how you might change colors or switch up what you're drawing when you're doodling, musicians in free improvisation can change the notes they play or the sounds they create whenever they want. It's all about exploring the endless possibilities of music and having fun while doing it.
