PITCH
High or low?
Pitch depends on how quickly something vibrates. Faster vibrations usually sound higher; slower ones sound lower.
A LITTLE SOUND SCIENCE
Sound is a
wiggle in the air.
A sound begins when something vibrates. Those tiny movements travel through air to your ears, where your brain makes sense of them.
VIBRATION → WAVE → SOUND
VOLUME
Loud or quiet?
Volume is connected to how big the vibrations are. Bigger waves usually carry more energy and sound louder.
TONE COLOR
What makes it unique?
Two instruments can play the same note and still sound different. That quality is called timbre, or tone color.
TRY A TONE
Slide from low to high.
Move the slider, then press play to hear a simple tone at that pitch.
A short tone is ready.
LOW ←→ HIGH
Keep the volume comfortable. Sound can be fun without being loud.
