Singing is really a very popular form of entertainment.
I don’t know if there is such a person around you, who can forget the original song when you speak, and even send people away.
The key is that I don’t know I’m out of tune, commonly known as “Pentagram incomplete”, so ugly but so confident…
Is “singing out of tune” a disease?
Unfortunately, most people are not sick, and a small number of people are really…
Is “singing out of tune” a disease?
Just as language barriers are called “aphasia”, there will also be barriers to the perception of music, which is medically called “aphasia”.
The research on aphasia-related lesions has a long history. As early as 1825, there was research on the difference in human perception of music. It was not until 1890 that the German doctor Noblek established a cognitive model of music processing and defined loss for the first time. Song syndrome (amusia).
Later, more and more scholars set foot in the field of aphonia, and it gradually became clear that the physiological differences between singers who sang out of tune gradually became clear.
At present, academic circles believe that aphasia is a kind of aphasia, caused by abnormal development of functional areas related to the dominant hemisphere of the brain or secondary to other diseases.
There are three common causes of aphasia, congenital, acquired aphasia, and pseudo-aphasia.
Congenital aphasia is caused by congenital developmental abnormalities in the functional areas of the brain.
Acquired dysphonia refers to some diseases that affect the brain’s language center and music processing functional areas, such as brain inflammation, hemorrhage, trauma, infarction, tumors, etc.
“Pseudo” aphasia may be caused by sudden and reversible nervousness.
Is “aphasia” just “incomplete pentatonic”?
First of all, it needs to be clear that a considerable part of the people with “pentatonic insufficiency” we usually call have a poor sense of music because they have not received orthodox temperament training, and they can sing beautiful songs with professional practice.
The aphasia usually has the following manifestations:
Hearing, intelligence and memory are normal, but the perception of music is extremely poor;
Cannot sing accurately, but often doesn’t know it, and even thinks that he sings very well;
I often feel confused because of poor understanding of rhythm and memory;
At the same time, 30% of patients with aphasia may also have communication difficulties.
Therefore, “aphasia” is not exactly the same as “pentatonic insufficiency”.
What causes the “aphasia”?
Some scholars have scanned the brains of people with aphasia and found that about 50% of people with aphasia have problems with rhythm recognition. The right hemisphere of the human brain is responsible for music, rhythm, imagination, color, etc. A variety of factors, including genetic abnormalities, can lead to music perception disorders.
Studies have also shown that aphasia is also related to the left cerebral hemisphere: after the left anterior temporal lobe lesions, the patient’s ability to recognize musical notes, sing, and even appreciate music may be partially or completely lost. “Qian sings to death by himself” at the scene of the car accident.
Different brain functional areas are damaged, and there are different manifestations of aphasia:
1. Expressive aphasia: impairment of singing, whistling and humming ability due to damage to the right frontal and temporal lobes;
2. Receptive aphasia: due to bilateral or unilateral (left or right) temporal lobe and parietal lobe lesions, the ability to distinguish between different melody is impaired;
3. Amnesia and song amnesia: Recognition of obstacles to the ability to familiarize themselves with melody (the existence of this condition is still controversial)
4. Music dyslexia: damage to the ability to write music scores due to damage to the left occipital lobe and temporal lobe;
5. Music dyslexia with dysgraphia: The ability to read and write music scores is impaired due to the injury of the left corner gyrus;
6. Music dysgraphia: The ability to write music is impaired due to the lesions near the left parietal sulcus;
7. Instrumental aphonia: The ability to play an instrument is impaired in music training due to injuries in different areas.
Why do people with aphasia fail to realize it?
Some scholars have proposed that the key process of singing includes the four processing processes of “pitch perception, sensorimotor conversion, vocal movement control, and memory”. Problems in any one of the links may lead to “incomplete pentatonic”.
Among them, the biggest and most common problem of patients with aphasia is often the perceptual impairment, that is, the inability to accurately recognize the difference between timbre, pitch, rhythm or intensity, and the inability to realize whether they are singing or whether they are in harmony or whether the rhythm is consistent and harmonious., etc.
Even after listening to a song many times, this melody is still unfamiliar to them. Just as people with color blindness cannot distinguish colors with similar wavelengths, people with aphasia cannot distinguish notes with similar pitches.
Can people who “sing out of tune” still be saved?
The general “pentatonic insufficiency” can sing a beautiful song as long as it is professionally practiced.
However, patients with acquired aphasia require early diagnosis and early treatment.
Pseudo aphasia can return to normal rhythm after improving external factors.
For patients with congenital aphasia, after the organic disease is excluded, let’s go with the flow~
After all, the incidence of “aphasia” in humans is as high as 4%. That is to say, except for the “pentatonic insufficiency” caused by various reasons, four out of every one hundred people will never be on the tune. We are not alone in the fight.
