A man in the band was striking an instrument called a triangle. It made a ringing sound.

“That sound reminds me of wind chimes,” said Jane.

“The triangle makes a soft ringing sound when it vibrates,” added Jim.

In this sample chapter, readers start to learn about Jane and Jim's walk from home. They explore why sounds can be startling (like sirens), soothing (like certain types of music), or mysterious (like eerie creaking in an empty house). By coming along, young readers of What Makes Different Sounds? can learn as the twins do. They’ll be introduced to the roles vibration, pitch, and volume play in how rustles, rumbles, and rat-a-tat-tats are made and transferred to their own ears.
