A sonata is a kind of music that tells a story. It's like a book, but instead of words, it uses different sounds to create a mood or feeling.
Imagine you're playing with your toys, and your mom asks you to tell a story. You might use your toys to act out the story and make different voices to show how the characters feel.
A sonata is kind of like that, except instead of using toys and voices, a musician uses instruments like a piano, violin, or cello to tell the story. The story is divided into different parts called movements, like chapters in a book.
Each movement can have a different mood, like happy, sad, or exciting. The musician uses different notes and sounds to create the mood.
So, listening to a sonata is like going on a musical adventure, where the musician helps you feel different emotions and experiences through the sounds they create.
