This is one of the most interesting effects inherent in some musical instruments and a chorus of people singing in about the same key — the formation of beats. When voices or instruments converge in unison, the beats slow down, and when they diverge, they accelerate.
Perhaps this effect would remain in the sphere of interests of only musicians, if not the researcher Robert Monroe. He realized that despite the beating effect widely known in the scientific world, no one had studied their impact on the human condition when listening through stereo headphones. Monroe discovered that when listening to sounds of similar frequency through different channels (right and left), a person feels the so-called binaural beats, or binaural rhythms.
For example, when one ear hears a pure tone with a frequency of 330 vibrations per second, and the other a pure tone with a frequency of 335 vibrations per second, the hemispheres of the human brain begin to work together, and as a result he hears beats with a frequency of 335 – 330 = 5 vibrations per second, but this is not a real external sound, but a “phantom”.

Music at all times, since its inception, has been used as a means of influencing people’s consciousness. With its help, different goals were achieved. Knowledgeable people wisely approached the musical design of their events.
For example, the Christian church forbade music in its churches, until the reign of Pope Gregory I, who allowed, and even wrote music for the performance of prayers. However, this music was supposed to be not emotional, without accompaniment, and the male choir sang songs in unison. This style is called Gregorian singing. Continue reading
Before modern neuroimaging techniques were developed, researchers studied the musical abilities of the brain, observing patients (including famous composers) with various disruptions in their activity due to injury or stroke. So, in 1933, the French composer Maurice Ravel developed symptoms of local brain degeneration – a disease accompanied by atrophy of certain sections of brain tissue. The composer’s mental abilities did not suffer: he remembered his old works and played scales well. But he could not compose music. Speaking about his alleged opera “Joan of Arc”, Ravel confessed: “Opera is in my head, I hear it, but I will never write it. Continue reading
