Music and hypnotic state

Hypnosis (Greek hypnos — dream) An altered state of consciousness characterized by a narrowing of its volume and presumably sharp focus on the content of the suggestion. Hypnosis occurs as a result of special effects of the hypnotist or targeted self-hypnosis. In a more general sense, hypnosis is a socio-medical concept of a complex of methods of targeted verbal-sound exposure to the human psyche through a mind braked in a certain way, leading to unconscious execution of various commands and reactions.

Hypnosis has been known to mankind for a long time, it was practiced by the priests of ancient Sumer. In the ancient world, on the basis of a hypnotic trance, almost the entire system of prophecies was built. Similar techniques were used not only by the initiates (priests and oracles). It is known, in particular, that contemporaries reproached the ancient Roman philosopher Apuleius for putting his slaves into a hypnotic trance in order to obtain a prediction of the future.

Why are our feelings and emotions changing while listening to music? We calm down or get excited. Why does music control us, forcing us to do things that we would never have done in a normal state? The answer lies in the structures of our brain.

The ability of music to influence human consciousness was known even to our ancestors. In ancient times, shamans brought people into a trance state with their hypnotic melodies. But the world does not stand still: people have changed, technologies have changed. And if shamans of ancient times used drums and tambourines, then modern shamans – DJ’s have different equipment: turntables, a mixing console and speakers.

It is scientifically proven that such sound instruments as the human voice, flute, drums and other percussion instruments affect the state of the human brain, or rather, its neurological activity.

For a correct understanding of this issue, you should first return to the school biology course. Both human cerebral hemispheres are responsible for various functions. The left is responsible for the conscious, verbal, logical, rational and analytical content. The right (non-dominant in most people) hemisphere is filled with abstract, synthetic, visual and intuitive content. When a person’s theta activity1 intensifies and he enters a hypnotic trance state, this means that the right hemisphere is actively stimulated. After all, it is the non-dominant hemisphere (again for the majority) that allows people to enter the euphoric state of a kind of nirvana.

The main “stimulants” for this condition are sounds and music, which stimulate an increase in the cellular activity of the human body. The connection between the non-dominant hemisphere and the spatial and intuitive aspects of human consciousness is very, very close, therefore music can enter a person into the so-called trance state without any medications at all.

Often we can see the expression of such an unusual state of consciousness (with a stimulated non-minisect hemisphere) in the form of an active perception of many psychic motives, such as deep emotions, fantasies and archetypal conflicts and dramas. Namely, in this state, feelings are aggravated, and perception becomes more active and refined. Simply put, a person’s sensitivity is enhanced, he begins to perceive what he previously did not pay attention to.

Various types of electromagnetic oscillations are recorded in the brain, from a slow alpha rhythm to a high-frequency beta rhythm. EEG rhythms of an adult awake man:

– alpha rhythm – frequency 8 … 13 Hertz, amplitude up to 100 microvolts. With an increase in the level of functional activity of the brain, the amplitude of the rhythm decreases and often it completely disappears;

– beta rhythm – frequency 14 … 40 Hertz, amplitude up to 15 μV. It disappears when performing or even imagining the movement;

– mu rhythm – frequency 8 … 13 Hertz, amplitude up to 50 mkv.

When two slightly different frequencies are superimposed, beats corresponding to this difference arise. We observed this while studying the vocals of opera singers. These beats can also be infrasonic. It doesn’t matter to the brain how you invoke the alpha rhythm that isn’t typical for it.

It is important that the fluctuation of the infra-low frequency affects the central nervous system and disrupts its work.

You can choose such rhythms and combinations of tones in a musical work that their harmonics, that is, sounds with frequencies that are multiples of the frequency of the fundamental tone (they determine the timbre, the character of the sound of the instrument), and the beats will be in the infrasonic range.

The most suitable for this selection are percussion instruments: drums, timpani, cymbals, etc. For modern percussionists performing the so-called pop music, whole percussion units are built on which they “play” with all four limbs. The sound, for example, of a drum during a single hit is explosive (carries a wide continuous spectrum containing all audible frequencies).
