- Sounds are created by vibrations or back and forth movements of objects. Energy is used to make the vibrations. The volume describes how loud or soft a sound is.
- When you change the vibration (fast or slow), you change the sound another way. This change in sound is called pitch. It is how high or low a sound is. Objects that vibrate faster have a high pitch. Objects that vibrate slower have a low pitch.
