Frequency of Music
Centuries ago musicians, composers and musical instruments had no standard frequency and were tuned to different Hertz. Seconds started being used as a units of time in the 16th century but it wasn’t until 1834 that the invention of the Savart Wheel and Tonometer (group of tuning forks) brought the measurement of cycles per second into focus.
In the 20th century, a group of influential musicians and physicists worldwide gathered and agreed to set A4= 440 Hz as the standard tuning for orchestras moving forward.
What is the big deal with these two numbers?
432Hz is closest to the harmony of the universe, natural middle C, Pi, musical healing frequencies, the Golden Ratio (which unites the properties of light, space, time, gravity, matter, DNA and consciousness) and the Schumann Resonance which is the pulse or heart beat of the earth.
Schumann Resonance
Scientists say “the Schumann Resonance is a natural electromagnetic frequency generated by the Earth’s magnetic field, which is created by the reflection of electromagnetic waves between the Earth’s surface and the ionosphere, forming the semblance of a spherical waveguide that maintains the equilibrium of the electromagnetic midst of planet Earth”. This number normally sits around 7.83Hz but has been increasing lately and can spike depending on Solar Flares and major weather events. Changes can also affect us which can feel like buzzing, tinnitus or anxiety – 7.83 Hz sits exactly at the boundary between Theta and Alpha brainwaves.
440Hz
440Hz is less than harmonic to humans. The controversy is… was this was done deliberately or out of ignorance? See the studies below.
What is a Hertz?
“Hertz” (cycles per second or pitch) as a measurement of frequency coined after Heinrich Hertz in the 1930’s. The average human can hear sounds between 20hz to 20,000hz. Dogs can hear sounds as high as 47,000 to 65,000 Hz, which is why we can’t hear a dog whistle.
If you’d like to test what your hearing range is in hertz, there is a free test here.
A free test for how loudly or quietly you can hear in both ears or separately – 250Hz with variety of loudness.
