This is how high or low a sound seems. A bird makes a high pitch. A lion makes a low pitch.
Pitch and loudness are two ways that sounds are different. Another way is in quality. Some sounds are pleasant and some are a noise.Compare the two waves on the right.A pleasant sound has a regular wave pattern. The pattern is repeated over and over. But the waves of noise are irregular. They do not have a repeated pattern.
