Amplitude, Frequency, and Pitch

Pitch is the highness and lowness of a sound.

Frequency is vibrations per second.  The more vibrations per second, the higher the sound.  If there are fewer vibrations per second, the pitch is lower.

Amplitude is the loudness of the sound.

This youtube video uses instruments and experiments to explain pitch, frequency, and amplitude.
