The sound of the harp has been used as healing music since prehistoric times.

The harp's tone has a unique fluctuation that is a balance between regularity and surprise, and has a soothing effect on the listener.

Furthermore, it contains certain frequencies that humans cannot hear, which can be expected to relax a tense mind and reduce stress.

Therefore, the harp is used for healing purposes in a variety of situations, and one of the reasons for this is scientific.

So this time, we will explain in detail the healing effects of the beautiful sound of the harp.

The harp's sound has a relaxing effect due to its "1/f fluctuation"

The harp has its roots in the bows used for hunting in ancient Mesopitamian civilization.

The beautiful sound of the harp, which has recently been adopted as music therapy and healing music, has a relaxing effect due to its "1/f fluctuation."

"1/f fluctuation" is a unique fluctuation (rhythm) that is on the verge of regularity and unexpectedness, which we unconsciously experience in our daily lives.

Specific examples include the sound of a flowing river and the sound of trees swaying in the wind. The fluctuations that we perceive visually, such as the flickering of a lit candle or the grain of wood, are also "1/f fluctuations," and have a healing effect that leads to a comfortable sensation.

If we think about the sound of a flowing river or the sounds of trees, we can see that "1/f fluctuations" depend heavily on natural sounds.

Many people find that hearing the sound of rain outside helps them sleep peacefully at night.

This is because the sound of rain contains "1/f fluctuations."

While there is a pattern that allows us to predict that "when the sound of the rain weakens, it will stop," there is also the surprise of it picking up momentum again, contrary to our expectations.

This is the "state where regularity and surprise are on equal footing" mentioned earlier, and it makes sense that "1/f fluctuations" make it so pleasant to listen to.

The reason the harp is used in music therapy and healing music is because, like natural sounds, it contains "1/f fluctuations," which have a relaxing effect.

Research methods vary depending on the research institution, but one interesting research result has been that "1/f fluctuations" have been observed in the second movement of Mozart's Concerto for Flute and Harp in C major, K. 299, in which the sound of the harp is clearly heard.

The harp contains high frequencies that can help reduce stress.

The sound of the harp contains high frequencies above 20KHz that humans cannot hear, and listening to it can have healing effects such as reducing stress and boosting the immune system.

The healing effect obtained by listening to high frequencies that are actually inaudible is called the "hypersonic effect," and is said to activate brain cells and relieve tension and anxiety.

The human hearing range is roughly from 20Hz to 20KHz, and sounds above and below this frequency are generally inaudible.

Even inaudible frequencies affect the human brain, activating the core brain parts that control the autonomic nervous system and emotions, such as the midbrain and hypothalamus, and amplifying brain waves known as "alpha waves."

"Alpha waves" are brain waves that occur when the mind and body are in a relaxed state, and are dominant when the brain feels comfortable, such as during meditation or before sleep.

Therefore, listening to the sound of the harp induces "alpha waves," which relieves mental tension and relaxes the mind and body.

It is said that the tone of the harp is strongly influenced by the above-mentioned "hypersonic effect."

The healing effects of the harp were recognized even before scientific evidence was provided.

The healing effects of the harp's sound have been known since before scientific evidence was provided as it is today.

There is an anecdote about a king of the Kingdom of Israel who appears in the Old Testament who suffered from depression, but was cured by listening to the sound of the harp.

The sound of the harp has long been loved as soothing music. When you feel stressed in your daily life or want to calm your mind, why not try listening to it through healing music or classical music?
