As you listen to this song, see if you can follow the path of a vibration from its source through the ear.
How do pitch and loudness affect vibrations?
Vibration is moving back and forth.
Vibration is moving back and forth.
Bells or birds or whispered words from moving vocal cords.
Vibration is moving back and forth.
Some sound waves were heard one day when someone used their voice.
They shook the air first here, then there and the ear—it had no choice!
Well, the waves went in and caused a din vibrating your ear drum.
Then three small bones picked up the drone and shook up—every one!
Refrain
Vibration is moving back and forth.
It is, ya’ll.
Vibration is moving back and forth.
Bells or birds or whispered words from moving vocal cords.
Vibration is moving back and forth.
Vibration—moving back and forth;
Vibration—moving back and forth, moving—back and forth, back and forth.
(Vibrations ride through things with tides, no matter what is said;
moving molecules quickly then bounce inside your head.)
The way came clear to the inner ear for a wild and crazy ride—
Though semicircular canals the fluid had to slide.1
Cochlea’s hairs sent nerves upstairs with a message for the brain.
Your brain heard words.
The words you heard were, “Sounds, they’re not the same!”
Low pitch—slow; high pitch—GO!
The frequencies aren’t the same.
Soft waves are small; loud waves are tall in the vibration game.
