In the last chapter, you learned how to add speech bubbles for your sprite, but the cat was still silent. That’s about to change. In this chapter, you’ll learn about the blocks in the Sound category, which enable you to add sound to your Scratch scripts. Combining the blocks in this category, you can add sound effects to your projects. You can create a song by playing different musical instruments and playing specific music notes. You can even record custom sounds to add dialog that helps tell a story in your Scratch project.
