[Column] Comprehensively elucidating the myth, history, science, and cultural influence of 432Hz music - What psychological effects does frequency have on music?

Prologue: Why is 432Hz treated as “special”?

Text: mmr｜Theme: About 432Hz, a mysterious and fascinating cultural phenomenon

A representative example of the theory of alternative frequencies for music that is being talked about on the Internet is 432Hz. Millions of ““432Hz Music” have been uploaded to YouTube, with everyone from the spiritual realm to electronica creators talking about this frequency using words such as ““healing,” ““cosmic harmony,” ““golden ratio,” ““ancient civilization,” and ““natural frequency.”

However, the debate surrounding 432Hz is complicated by facts, misunderstandings, and spiritual symbols. どこからが歴史で、どこからが現代的神話なのか が分かりにくい。

In this paper,

Music history (history of tuning)
Scientific verification (psychological/physiological data)
Cultural History (Mysticism/1960s New Age)
Media spread (YouTube/healing boom)

We will comprehensively analyze why 432Hz attracts so many people.

Chapter 1: History of tuning - until 440Hz was standardized

1-1. Pre-modern times: completely different pitches depending on region and era

From the 18th to the 19th century, the standard pitch of music (A frequency = A frequency) varied by region, instrument, and era. A fluctuated in the range of 380Hz to 470Hz.

Baroque Europe: Frequently around 415Hz (modern “Baroque pitch”)
Northern Italy (18C): Approx. 430Hz
French court (18C): approx. 392Hz (“Tonneau Bass”)

In this way, “432Hz” is not the “correct pitch” in history, but A region around 430 to 435 Hz actually existed, so it can be said that misunderstandings were likely to occur in future generations.

1-2. Industrialization and internationalization required a “unified pitch”

In the latter half of the 19th century, as orchestras became huge and exchanges between European cities increased, Differences in pitch from place to place began to cause confusion at concerts.

Following this trend, France established A=435Hz (commonly known as the diapason norm) (1859). この値が後に「432Hzが古典の正統ピッチ」と誤解される一因にもなった。

1-3. 20th century: International standardization of A=440Hz

1939: A=440Hz proposed at the London Conference
1955: Officially adopted as an ISO standard
1975: Revised as ISO 16, current

In other words, 440Hz is a “convenient standard created by modern internationalization”, The decision was not made based on musical or spiritual superiority.

Chapter 2: Is 432Hz really a “natural frequency”?

The claims made on the internet about 432Hz are as follows.

Universal Harmonic Frequency
Compatible with earth vibration (Schumann resonance)
Relationship with golden ratio φ
Has health and healing effects

However, from a scientific perspective, most of these claims have no direct causal relationship.

2-1. Unrelated to Schumann resonance (7.83Hz)

The fundamental tone of the Schumann resonance that exists in the earth’s electromagnetic environment is “7.83Hz”.

7.83Hz × 55 ≒ 430.65Hz
7.83Hz × 56 ≒ 438.5Hz

**Even integer multiples do not match 432Hz. **

2-2. The relationship with the golden ratio φ (1.618…) is also “number matching”

It is true that the number 432 has been used in various mystical systems; 周波数としての432Hzとφの関係は数学的に必然ではない。

2-3. Only “timbre change” can be confirmed scientifically

When converting the same song to 432Hz and 440Hz, 8Hz差による音色・テンションの“微妙な違い”が生じる。

432Hz → Slightly soft, impression of less sound pressure
440Hz → Modern music, clear, and easy to edge

People’s impressions are easily influenced by this, but Research data showing clear physiological advantages are currently limited.

Chapter 3: 432Hz from psychological and physiological data

Often cited in the following studies:

432Hz music is slightly more likely to lower your heart rate
Tendency for subjects to report feeling “calming” and “warm”

However, the difference in effectiveness is small;

432Hz → Easy to relax
440Hz → Easy to concentrate

No clear superiority difference beyond this “tendency” has been proven.

Rather, if you have an expectation that “432Hz is a soothing sound”, Feeling good due to the placebo effect is quite possible.

Chapter 4: Why has the “432Hz myth” spread rapidly in modern times?

4-1. Originated from 1970s New Age culture

Sound therapy
Connection between chakras and musical scales
Mystical numerology (432, 108, 144…)

この文化圏で、数字の象徴性と音楽が結び付いた。

4-2. After 2000s: Explosive spread on the Internet

YouTube was a platform where you could easily share ““famous songs converted to 432Hz’’.

-EDM

Lofi
Ambient
sleep music
1/f fluctuation BGM

Both creators and listeners praised the “soft sound” 432Hz has penetrated across genres.

4-3. The “narrative” of numbers gained support

Many of the people who support 432Hz I’m more attracted to the “storytelling” than the numbers themselves.

Mysteries of ancient civilizations
Harmony with nature and the universe
Elevation of spirituality
The healing power of music

This is an attraction that is on a different level than whether it is true or not. This is a major reason why 432Hz has become a cultural phenomenon.

Chapter 5: Music Production Perspectives - What actually changes with 432Hz conversion?

5-1. Conversion in DAW

Decrease 440Hz recording by –31.766% cents
Or create a new project with A4=432Hz

5-2. Differences in tone

The “hardness” of the high range is slightly softened.
Sounds more atmospheric
歌声がわずかに丸く聞こえる

Many producers say that it has a particularly positive effect on vocals.

5-3. Most important: The key of the song changes

432Hz lowers the entire pitch, so Please note that if you match it with a 440Hz performer, it will be out of sync.

Although it is unrealistic for classical music or band performances, This is not a problem with YouTube’s background music.

Chapter 6: “Belief” and “musical reality” surrounding 432Hz

The important point is that the experience of listeners who prefer 432Hz is not a lie.

Impression of “calming” and “soft”
How addictive the creator feels
Emotional value created by the symbolism of numbers

This exists as a cultural/psychological reality that is separate from scientific proof.

Music is originally It is a field where science, sensation, and storytelling coexist, and 432Hz can be said to be a symbolic phenomenon.

Summary: 432Hz is a “mysterious and fascinating cultural phenomenon”

There is no special historical basis
Not scientifically better than 440Hz
However, as a cultural phenomenon it is very interesting. Has the power to enrich the listener’s experience

In other words, 432Hz is
