Question

pitch refers to ____.

○ a specific frequency of a musical sound.

○ a hard - shelled bug

○ a specific frequency of a musical sound and how long that sound occurs.

Explanation:

In the context of music (or acoustics, a subfield of Natural Science - Physics), pitch is defined as the perceived frequency of a musical sound. The option "a hard - shelled bug" is irrelevant to the musical/acoustic definition of pitch. The third option is incorrect because "how long that sound occurs" refers to duration (or time - related aspects of sound), not pitch. So the correct definition of pitch is a specific frequency of a musical sound.

Answer:

a specific frequency of a musical sound.
