What is the symbol of frequency? The symbols most often used for frequency are f and the Greek letters nu () and omega (). Nu is used more often when specifying electromagnetic waves, such as light, X-rays, and gamma rays.
The Hz express the cycles per second (1 Hz = 1 cycle per second). Specifically, the frequency values determine the tonality and influence the timbre of the sounds. The current reference frequency for tuning musical instruments is 440 Hz, which corresponds to the musical note A4 (LA3) in the central octave of the piano.
Because of this harmonic misalignment, listening to 440 Hz music would seem to make people anxious, nervous, or aggressive, because it is not in harmony with the natural frequency of the planet earth.
Studies have shown that this frequency has a natural resonance with our bodies, meaning it is in harmony with our own biological vibrations. Researchers have found that listening to sounds at 432 Hz has a calming effect on the brain and nervous system.
Conclusions: The data suggests that 432 Hz tuned music can decrease heart rate more than 440 Hz tuned music. The study results suggest repeating the experiment with a larger sample pool and introducing randomized controlled trials covering more clinical parameters.

432 resonates better and clearer with water, and since our bodies are mostly water, it resonates better with us. Around the Baroque-classical era, people in various cities decided to start tuning their instruments higher and higher to sound more and more brilliant than the other orchestras.
A sound played at 432 Hz is technically the note A (A4, more specifically). Compared to A4 = 440 Hz, however, the pitch of 432 Hz will sound a bit flat.
In 1939, it was decided to change from 432 Hz to 440 Hz in sound recordings. Some theorists said there was an purposeful degradation of the natural sound.
