Beneficial music frequencies
The New Age movement has brought attention to musical frequencies that benefit our body and mind. Many musicians and theorists support this theory.
Let’s start with the 8Hz frequency. They consider this the “pulse” of the planet and the natural ecosystem, also referred to as the “fundamental Schumann cavity resonance.” 8Hz is the frequency on which the DMT molecule produced by our pineal gland operates; 8Hz is the replication frequency of human DNA and 8Hz is also the rhythm of the Alpha waves of the brain in which our brain bi-hemispheres are synchronized to work together.
Therefore, according to this interesting theory, resonances that are multiples of 8Hz result naturally aligned with the underlying frequencies of our organism. In fact, by tuning A (LA) to 432 we arrive at a C (DO) of 256Hz, and within this scale 8Hz becomes the 27th sopratone of C. By the principle of harmonics according to which multiples and submultiples of that frequency are added to a sound produced, the C’s of the other octaves will also begin to vibrate by “sympathy,” making the 8Hz frequency resonate naturally.
So after some research, some theorists argue that only by synchronizing on the A (LA) at 432Hz sound waves can have a beneficial effect, which change bodily characteristics such as breathing, heartbeat, sweating, brain waves and neuro-endocrine response, stimulating balance and relaxation of mind and body.
To date, however, the reference frequency for tuning musical instruments is 440 Hz, which corresponds to the musical note A4 (LA3) in the middle octave of the piano. A change that took place around the 1950s, theories about it circulate on the web without firm evidence, among them the most interesting one even accuses Nazi propaganda minister Joseph Goebbels, who through 440Hz musical frequencies wanted to make the German population more aggressive. Songs tuned to 432 Hz can be found in the New Age music genre, in music used for meditation, and on YouTube it is possible to find some well-known pieces of music transposed to 432 Hz from the original tuning of 440 Hz.
So far, experiments have not been massive to confirm this theory, but in Italy in 2019, some researchers carried an interesting experiment out involving 33 volunteers, without chronic and acute diseases. They placed these volunteers in a soundproof room, but first they measured their vital parameters (blood pressure, heart rate, respiratory rate, oxygen saturation), and perceptual (physical and emotional sensations, for example, fatigue and stress). On the first day, they listened to music for half an hour in 440Hz frequencies, while on the second day they listened to music in 432Hz frequencies.
Results show that 432 Hz tuned music was associated with a slight decrease of mean (systolic and diastolic) blood pressure values (although not significant), a marked decrease in the mean of heart rate (−4.79 bpm, p = 0.05) and a slight decrease of the mean respiratory rate values (1 r.a., p = 0.06), compared to 440 Hz. The subjects were more focused on listening to music and more generally satisfied after the sessions in which they listened to 432 Hz tuned music. In conclusions, the data suggest that 432 Hz tuned music can decrease heart rate more than 440 Hz tuned music.
We hope that many more researchers will take an interest in this topic and propose interesting new experiments on it.
