Book music is like a special book that has words and pictures, but instead of just reading the words, you can hear music as you read along. Imagine reading a story about a happy family having a picnic, and you can actually hear the sounds of laughter, birds chirping, and even a guitar playing in the background as you read.
The book has a special code or symbols that tell a music player what to play at specific times while you read. It's like a secret message that only the music player can understand. So the music player will start playing the sounds or songs that match the words and pictures in the book.
Sometimes these types of books are used to teach kids about music or different instruments. So as they read the book and hear the sounds, they also learn about how different instruments sound and how they can be used together to make beautiful music.
Overall, book music is a fun and creative way to bring stories and music together for young readers.
