What is Pitch in Music?
Pitch in music refers to the perceived frequency of a sound wave. It determines whether a sound is high or low in tone. The pitch of a sound is directly related to the frequency of the sound waves producing it. A high frequency corresponds to a high pitch, while a low frequency corresponds to a low pitch.
In Western music, standard pitches have been used to facilitate tuning among various performing groups. The reference pitch for tuning is usually set at A above middle C (C4). The current standard pitch is A = 440 Hz, which was adopted in 1939. Prior to that, A had been set at 435 Hz. The rise in pitch over time necessitated an international agreement on standard pitch.
How is Pitch Measured?
Pitch can be measured in two main ways: scientifically and musically. Scientifically, pitch is measured by determining the number of times a sound wave vibrates per second, which is expressed in Hertz (Hz). Musically, notes are assigned alphabetical letters between A and G, and each note corresponds to a specific pitch. For example, A4 represents a specific pitch.
Relationship between Pitch, Note, and Tone
In music, a note is a named pitch. It is an arbitrary designation given to a specific pitch. For example, in Western music, the pitch of 440 Hz is commonly referred to as A, specifically A4. A note can also refer to the occurrence of a pitch. For instance, playing A4 twice can be described as "playing one note twice" or "playing two notes" depending on the context.
Tone, on the other hand, refers to the quality or character of a sound. It is influenced by various factors such as the instrument or voice producing the sound, the technique used, and the presence of harmonics. While pitch refers to the perceived frequency of a sound wave, tone encompasses additional aspects of sound quality.
Conclusion
Pitch in music refers to the perceived frequency of a sound wave and determines whether a sound is high or low in tone. It is measured scientifically in Hertz and musically through alphabetical letters assigned to notes. Understanding pitch is essential in music theory and production, as it forms the foundation for melody, harmony, and other musical elements .
The specific quality of a sound that makes it a recognizable tone. Pitch defines the location of a tone in relation to others, thus giving it a sense of being high or low.
