Okay, let's imagine you have a toy that you really like to play with. But as you grow older, you start to want different kinds of toys to play with. This is kind of like how music has evolved over time.
A long, long time ago, people would make music by banging on things like rocks or pieces of wood. Then, as time went on, people started to make instruments out of things like hollowed-out logs and animal skins. They also started to sing and make melodies with their voices.
As people traveled and traded with each other, they started to learn about new instruments and styles of music. This is kind of like how you might learn about new toys from your friends. People also started to use music for different things, like telling stories or celebrating important events.
Over hundreds and hundreds of years, music continued to change and grow. People invented new instruments, like the guitar and the piano, and started to write down music so that it could be shared even more widely. Musicians also started to experiment with new sounds and styles, which led to the creation of things like jazz and rock music.
Today, there are all kinds of different types of music that people enjoy listening to. Some people still love the classical music of Bach or Mozart, while others prefer the pop music of Beyoncé or Justin Bieber. The evolution of music is like a big, never-ending story, and we all get to be a part of it!
