Why are some people singing?

In the case of congenital factors, genetic (gene) and other reasons lead to the "music brain" to identify obstacles to the pitch, and this recognition disorder will be amplified in the real music environment, and then music-related Memory impairment. From the point of view of acquired development, when the brain produces lesions, it may cause the patient to lose part or all of the existing cognitive notes, singing rhythm and ability to enjoy the music.
Singing is not a tune, also known as "losing songs", is an abnormal expression of the tone is not accurate, there are defects in music, often accompanied by problems in music memory and recognition.
Statistics show that 10% of people have congenital five-tone insufficiency, singing and running. 4% of them are congenital desensitization for fine tone recognition. In 2002, researchers at the University of Montreal in Canada conducted a comprehensive scan of the brains of people with singers. It was found that about half of the singers had problems in rhythm awareness and found a distinction between pitch and memory melody. The brain white matter of the brain area concerned is slightly different from that of ordinary people. They speculate that there should be a "module" in the human brain that deals with music. When this part is not fully developed, it is easy to cause symptoms of singer.
Why do people suffer from singer? There is no definitive research yet. But in theory, it should be the result of a combination of innate genetic factors and acquired environment. In terms of congenital factors, the right hemisphere of the human brain is responsible for human imagination, color, music, rhythm, etc. Genetic (genetic) and other reasons lead to the "music brain" to identify obstacles to the pitch, and this recognition Obstacles are magnified in real-life music situations, leading to music-related memory impairments. Just as a weak person can't distinguish the colors with similar wavelengths, the loser can't distinguish the notes with similar pitches. Of course, studies have also shown that sing-song is related to the development of the left frontal lobe of the brain. The motor language center in the frontal lobe of the left hemisphere, management language, personality, judgment, attention, writing and other functions, are closely related to the clear expression of emotions and the accurate imitation of sound. When the left lobes of the left hemisphere produce lesions in the anterior temporal lobe, it is easy to cause the patient to lose part or all of the existing cognitive notes, singing performances and the ability to enjoy the music, and then show their singing and running.
In 2009, researchers at the University of Helsinki in Finland conducted long-term follow-up studies of the left or right hemisphere middle cerebral artery in 53 stroke patients. The results showed that the left and right hemispheres of the sing-song group were not much different from the normal population, but the sing-song group often had more frontal and auditory cortical lesions. The results of the trial showed that the occurrence of acquired singer is related to a series of cognitive functions, attention concentration, brain function, and memory ability.
Of course, many studies on sing-song also support the importance of multiple cortical regions such as the primary auditory cortex, the secondary auditory cortex, and the limbic system in the processing of music. The researchers believe that lesions in other cortical areas, as well as abnormalities in cortical thickness, nerve connections and defects in brain plasticity, are also associated with the occurrence of sing-song.
Other studies have shown that the processing of tones is generally controlled by the right sacral region of the brain (this region has the function of distinguishing melody, tone and interval information), and the normal secondary auditory cortex processes the changes in tone and manipulates the correct phonetic intonation. . Recent rhythm-resolved trials suggest that the lack of interconnection between the sacral region and the neuromotor zone is likely to be an important cause of congenital or acquired chorus.
In addition, memory is an internal representation of the recognition and recording of tunes, which helps to identify familiar songs and the ability to sing songs into the brain, so the damage of memory will also greatly contribute to the occurrence of singer.
