Musical height

In music, musical height is one of the four essential qualities of sound, along with duration, intensity, and timbre. This quality determines whether a sound is high-pitched or low-pitched, which will depend on the frequency at which the sound wave is repeated. The higher the repetition of the wave, the higher the sound will be and the lower the repetition, the lower the sound will be. For this reason, musical notes are determined by a frequency number. In psychoacoustics pitch is a parameter used to determine the perception of the pitch of a sound.

The height of sounds depends on the vibration frequency of the sound body. High-pitched sounds are the result of a greater number of vibrations compared to low-pitched sounds, whose variation number is lower.

Sound waves are always caused by the vibratory movement of some body in contact with a medium in which sound is possible, be it the harmonic or resonance box of a piano or the diaphragm of a drum. In wind instruments, the vibrating body is a column of air. Frequency is measured in hertz, the number of times a sound wave vibrates in one second. The higher the frequency of the sound wave, the higher the pitch of the sound, or higher pitched.

There are various sub-contents within height: its variations, continuous and gradual, the registers, whether it is fixed or variable, determined or indeterminate.

The lower threshold of human hearing is between 16 and 20 Hz, and the upper threshold between 16,000 and 20,000 Hz, depending on the individual’s hearing. Sounds below the lower threshold or above the upper threshold are not registered by the ear, due to natural limitations of the human hearing system. Sounds above the upper threshold are called ultrasound. A mixed choir moves between 82.4 and 1046.5 Hz and a grand piano between 27.5 and 4186 Hz (values ​​refer to fundamental frequencies).
