low pitch
Definition
Pitch is the characteristic of sound that makes it sound high or low. It is determined by the frequency of the sound wave.
Sound waves are vibrations that travel through the air. The frequency of a sound wave is the number of vibrations that occur in a given amount of time.
Sounds with low pitch have low frequencies. This means that they have long wavelengths.
Sounds with high pitch have high frequencies. This means that they have short wavelengths.
The human ear can hear sounds with frequencies between 20 Hz and 20 kHz. Sounds with frequencies below 20 Hz are called infrasound, and sounds with frequencies above 20 kHz are called ultrasound.
How can the word be used?
The cello has a low pitch.
Different forms of the word
The word "low pitch" is an adjective that describes a sound that has a low frequency. It does not have any other forms.
Etymology
The word "low pitch" is an adjective that describes a sound that has a low frequency. It comes from the combination of two words:
Low: An adjective that describes something that is not high.
Pitch: The frequency of a sound.
The word "low" comes from the Old English word "lōw", which also means "not high". It was first used in English in the 8th century.
The word "pitch" comes from the Old English word "pīht", which also means "the frequency of a sound". It was first used in English in the 10th century.
The word "low pitch" was first used in the 16th century. It is used to describe a sound that has a low frequency.

What does low pitch mean?
AQA Science Exam Question and Answer
Question:
Explain the concept of low pitch in the context of sound waves and provide an example to illustrate how it is perceived.
Answer:
Low pitch refers to the characteristic of a sound that is perceived as having a lower frequency. Sound is a mechanical wave that travels through a medium, such as air or water, as a series of compressions and rarefactions. The frequency of a sound wave determines its pitch, where higher frequencies correspond to higher pitches, and lower frequencies correspond to lower pitches.
For example, a deep voice is often associated with low-pitched sounds. This is because the vocal cords of individuals with deeper voices vibrate at a slower rate, producing sound waves with lower frequencies. When these lower-frequency sound waves reach our ears, they are interpreted by the brain as having a lower pitch.
In terms of musical instruments, a tuba or a bass guitar typically produces low-pitched sounds due to their longer and thicker strings or tubes, which vibrate at lower frequencies compared to, say, a flute or a violin.
