Question

Define pitch of a sound.

Answer 1

Hint: Pitch of a sound is an attribute of the sound that tells us about its frequency. A sound that is at a high pitch, has a high frequency. And a sound at low pitch has lower frequency.

Complete step by step answer:
When a singer is singing we sometimes say that the singer is singing at a high pitch or sometimes we say that the singer is singing at a lower pitch. What do we mean by the term pitch? The term pitch is used to differentiate between sounds. It sets a level or a scale to a sound. That is why we used the words low pitch and high pitch.

We relate the pitch of the sound with the frequency of the sound. The sounds that have high frequencies are said to be at high pitch. The sounds that have low frequencies are said to be at low frequency.
Therefore, when we say that the singer is singing at a high pitch, we mean that the frequency of her voice is high. When the frequency of her voice becomes low, we say that she is singing at a lower pitch.
Hence, pitch of a sound is a term that tells us about the frequency of a sound.

Note:
A.)Students may misunderstand that pitch and frequency of a sound are the same. Note that the two are not the same but related because frequency tells whether the pitch is high or low.
B.)Frequency is a physical quantity that can be measured. Whereas we cannot measure pitch of a sound. It has only two values- high and low.
