Sounds are part of our life, and when they are harmoniously combined in frequencies and rhythms, they become music, which, in turn, since ancient times has been part of civilizations and cultures around the world, expressing feelings and emotions in the most varied styles.

Even music has a great influence on people, and can be used to cheer, energize, relax, and generate various behaviors, depending on the oscillation of sound waves per second with which it is produced, called frequency.

Frequency is measured in Hertz (Hz), a unit of the International System (SI), which is equivalent to one second. It is currently standardized at 440 Hz. But do you know what this means? Read on to find out!

What is the 440 Hz frequency?

In general, societies have their own combinations of musical notes, scales and rhythms, but in order for musical instruments to sound good and have cohesion, they are tuned considering one of the musical notes and a certain frequency.

And when 440 Hz is mentioned, it means that a sound wave vibrates 440 times in one second on the note A. It also refers to the tuning standard for the musical pitch used on all instruments, as established by ISO 16 (1955) of the International Organization for Standardization. However ISO 16 is not a law, and therefore musicians, bands and artistic communities have the freedomto choose other tunings.

What is the 440 Hz frequency for?

The adoption of a certain frequency, as explained above, is a choice, not an imposition, so much so that musicians today can use 432 Hz, 444 Hz, and others, according to intuition or personal taste.

But imagine a conductor who is going to perform with an orchestra in a certain place where the instruments have one tuning and then goes to another place with completely different tuning, having to present the same musical composition. Imagine in an orchestra instruments with different tunings. Even for untrained ears, it could sound inharmonious. So the frequency 440 Hz was adopted forpromote a standard and achieve musical cohesion anywhere, among other factors.

As far as hearing is concerned, this frequency is not so different from 432 Hz, adopted by Verdi and which was widely used by classical composers of the time. It even gives the impression of more vigor to the orchestra, for example. For our ears, the frequency 440 Hz may not be perceived differently from that adopted by the Italian composer. But it may demand more of the singers, who, inreason of higher notes, they need to raise their vocal pitch.

Is the 440 Hz frequency bad for you?

There are many theories about the purpose of the 440 Hz frequency, because until the middle of the 20th century 432 Hz was common. One of them points out that Joseph Goebbels, Nazi Propaganda Minister, determined that the German standard should be changed to this new frequency, believing that it could be used to control hearts and minds, facilitating the supremacy of Nazi troops over nations. Also theThe United States, under the influence of the armed forces and economic groups, began to use this frequency.

According to Dr. Leonard G. Horowitz, filmmaker, expert in media persuasion, and author of 16 books, the music industry is using the 440 Hz frequency to massify entire populations, causing increased aggressiveness, psychosocial turmoil, emotional distress in people, and materialistic consciousness, with the goal of domination and increased profits.

In Italy studies have been developed in order to identify, scientifically, the influences of musical frequencies on people, as is the case of "Music Tuned to 440 Hz Versus 432 Hz and the Health Effects: A Double-blind Cross-over Pilot Study," published in July 2019, in the Explore Journal, New York, in the United States, which concluded, even though, in a small sample, the frequency432 is more effective in reducing heart rate than 440 Hz.

Considering that music is everywhere and is heard at 440 Hz, most of the time and by a large number of people, some spiritualist doctrines believe that it could reduce the capacity for personal relationships due to the psycho-spiritual maladjustment caused by the conflict it generates in the chakras.

What are the benefits of the 440 Hz frequency?

The question remains: if the 440 Hz frequency is capable of provoking aggression, emotional suffering, and materialistic consciousness, yet less supportive of physical well-being than 432 Hz, why is it still being used?

Along with efforts to achieve a more united and open world, the idea of the 440 Hz frequency as a standard came to eliminate international tuning disputes and to express rationalization in the musical realm.sold worldwide, even though the musical styles are different.

To conclude, despite conspiracy theories that 440 Hz is not beneficial, it is the current standard for instrument tuning and music production. While it influences our daily lives, it is also in harmony with the consciousness it represents. Moreover, if there is a dark intentionality to its adoption, it is also a source of reflectionThink about it and listen to some good music!
