Meinl Tuning Fork Earth, TF-E, 136,10 Hz

Orbital Frequencies

Based on precise calculations of planetary constellations within our solar system, Hans Cousto was able to determine the exact frequencies of each planet and asteroid in relation to the Sun. Central to his method were the time each object takes to orbit the Sun, as well as the duration of its own axial rotation. By applying multiple octave transpositions to these frequencies, the resulting tones can be shifted into the audible range and expressed through musical instruments.

History and Applications

The idea that the universe follows musical harmony is far from new. The ancient philosopher Pythagoras and his followers already believed in a deep connection between musical intervals and the motion of celestial bodies. Since then, countless theories and writings have explored this relationship, particularly within esoteric traditions and sound therapy.

Sonic Energy Collection

Meinl’s Sonic Energy Collection draws on this concept of cosmic harmony, offering instruments such as tuning forks, gongs, energy chimes, singing bowls, and cymbals tuned to the frequencies of the planets in our solar system. These instruments are ideal for creating meditative, therapeutic, and otherworldly soundscapes—either solo or in group settings.

The MEINL Tuning Fork Earth is part of the Meinl Sonic Energy Collection and is made in Germany. It measures 204 millimeters in length and its frequency is based on Earth’s orbital period around the Sun, as the third planet in our solar system. The orbital period is one year, equivalent to 365 days or 31,556,925.9747 seconds. From this, the fundamental frequency is calculated as 1 divided by the orbital period in seconds, resulting in approximately 3.1689 times ten to the negative eighth Hertz. After multiple octave transpositions, the audible frequency reaches 136.10 Hertz, corresponding to the tone C sharp three, also known as the OM tone. This tuning fork is based on the 432.09 Hertz tuning standard for A4.
