How is pitch related to frequency?

Pitch is directly related to frequency, which is the number of vibrations or cycles per second measured in hertz (Hz). When the frequency of sound waves increases, it results in a higher pitch that is perceived by the human ear. For example, if you consider a musical instrument like a guitar, playing a string with a higher tension or a shorter length increases the frequency of the sound wave produced, leading to a higher pitch sound.

In contrast, lower frequencies correspond to lower pitches, which is why sounds like a bass drum or a tuba are perceived as having a lower pitch. The relationship between frequency and pitch is consistent throughout the range of sounds we can hear. Essentially, frequency determines how high or low the pitch of a sound is, making it a fundamental concept in understanding sound and music.
