WHAT IS SOUND?
Sound is a type of this.
➡️ Energy
What type of motion creates vibrations?
Back-and-forth motion
What form does sound take as it moves through a medium?
Waves
Name the three states of matter that can carry sound.
Solids, liquids, gases
What causes sound in all musical instruments?
Vibration
Sound is created when something does this.
➡️ Vibrates
How does the strength of a vibration affect loudness?
Stronger vibrations create louder sounds
Why does sound need a medium to travel?
Particles are needed to carry vibrations
Which state of matter allows sound to travel the slowest and why?
Gases; particles are farther apart
What vibrates inside a baritone to produce sound?
The air column
We hear sound when vibrations reach this part of the body.
Ears
How does vibration speed relate to pitch?
Faster vibrations produce higher pitch
Describe how sound travels from its source to a listener.
Vibrations move through a medium to the ear
How does particle spacing affect sound transmission?
Closer particles transfer vibrations faster
How does changing finger placement affect sound in a brass instrument?
It changes tubing length and pitch
True or False: You can see sound with your eyes.
False
Why do smaller instruments often produce higher sounds than larger ones?
They vibrate faster
Why does sound travel faster in solids than in gases?
Particles are closer together
Why can you hear sounds through a wall but not through empty space?
Walls have particles; space does not
Why does longer tubing create lower pitches in brass instruments?
Vibrations move more slowly
Sound travels as this.
Waves
Explain how both pitch and volume are controlled by vibrations.
Speed affects pitch; strength affects loudness
Predict what would happen to sound in a vacuum and explain why.
It would not travel because there are no particles
Compare sound travel in water versus air.
Sound travels faster in water because particles are closer
Explain how a baritone demonstrates both sound production and sound travel.
Air vibrates to produce sound waves that travel through air to the ear
