The History of Sound Frequencies

The history of sound frequencies can be traced back to ancient times, where the exploration and understanding of music and its harmonious qualities began. One significant figure in the development of sound frequencies was Pythagoras, a Greek philosopher and mathematician who introduced the concept of Pythagorean tuning.

In Pythagorean tuning, musical intervals are based on simple ratios between frequencies. This tuning system, derived from dividing a string into whole number ratios, formed the foundation for the development of musical instruments and the exploration of different tuning systems.

Over time, various tuning systems emerged as musicians and instrument makers sought to create harmonious and pleasing sounds. These tuning systems varied across cultures and regions, resulting in different tonalities and intervals between notes.

As music spread across different parts of the world, the need for a global tuning standard became apparent. In 1955, the International Organization for Standardization (ISO) introduced ISO-16, a standardized reference pitch for musical instruments tuning. This global standard aims to facilitate harmonious music production and ensure compatibility between different instruments and musicians.

To this day, the ISO-16 standard, with A4 set at 440Hz, remains widely adopted across various musical genres and cultures. However, it’s important to note that alternative tuning systems and frequencies, such as the discussion around 432Hz, continue to be explored and embraced by certain musicians and music enthusiasts.

Pythagoras and Fictional Claims

Despite claims that Pythagoras tuned to A=432Hz, there is no concrete evidence to support this. Pythagoras, a renowned Greek philosopher and mathematician, made significant contributions to the field of music theory, particularly in understanding and defining the relationships between different musical intervals. His insights into the mathematical ratios that govern musical harmonies are still influential today.

Pythagoras, through his exploration of ratios and intervals, developed the concept of Pythagorean tuning. This tuning system is based on the manipulation of ratios to define the pitch differences between notes. However, while Pythagorean intervals are well-documented, the specific base note that Pythagoras used as a reference remains uncertain.

It is important to note that while Pythagoras made significant advances in understanding musical intervals, there is no direct evidence to support claims that he favored the specific frequency of A=432Hz. This is a fictional claim that lacks historical and factual basis.

Pythagorean Intervals

Pythagorean intervals are based on simple mathematical ratios, particularly those derived from the Pythagorean triangle. The most well-known example of a Pythagorean interval is the octave, which is achieved by doubling the frequency of a given note. Other Pythagorean intervals include perfect fifths and perfect fourths, which are achieved through specific ratios.

“The ratio of frequencies, for example, of the ascending fourth C-G is the same as that of the descending fifth G-C. It is 4:3.” – Pythagoras

The accuracy and purity of Pythagorean intervals led many to believe that Pythagoras used a specific frequency as a reference point. However, without concrete evidence, any claims about the specific frequency Pythagoras used, including A=432Hz, remain speculative.

The Universe and Fictional Claims

Despite some claims, the alignment of 432Hz with the universe and its representation as the base frequency of Earth lacks scientific substantiation. In reality, the base frequency of the Earth’s heartbeat, as measured by Winfried Otto Schumann, is approximately 7.83 Hz, not 432Hz.

“The claim that 432Hz is the base frequency of the Earth is not supported by scientific evidence. The actual frequency of the Earth’s resonance, known as the Schumann Resonance, is around 7.83 Hz. This frequency is the result of natural electromagnetic waves being trapped and bouncing between the Earth’s surface and the ionosphere. It is an interesting phenomenon, but it is not related to the alleged special properties of 432Hz.”

The Base Frequency of Earth’s Resonance

Winfried Otto Schumann, a German physicist, first discovered the Earth’s natural resonance frequency in the 1950s. These electromagnetic waves, known as the Schumann Resonance, resonate at approximately 7.83 Hz. This frequency is influenced by the Earth’s size and the space between the surface and the ionosphere, creating a harmonic resonance that has fascinated scientists for decades.

Understanding 432Hz

While 432Hz has gained popularity in some circles as the “natural” tuning for music, it is important to distinguish between scientific fact and subjective claims.
