The Mozart Effect

A gray-haired older woman sat motionless with her gaze lowered. In the late stages of dementia, she no longer spoke to others or made eye contact. When Ayako Yonetani started playing the violin, the woman slowly lifted her head. “Her mouth moved, and her eyes brightened as if she heard my music and was trying to follow it,” recounted Ms. Yonetani, a concert artist and professor of violin and viola at the University of Central Florida School of Performing Arts. Those who spent time with the woman were astonished. “They had never seen her react like this before,” she said. But this was only one of many times that Ms. Yonetani had seen such a thing.
Clear Evidence One study published in the 1990s in the journal Nature drew people’s attention. Three groups of participants were instructed to either sit in silence, listen to a relaxation tape, or listen to Mozart’s Sonata for Two Pianos in D major (K448). Ten minutes later, the group who listened to Mozart’s music showed a significant improvement in spatial IQ score—nearly 10 points higher than the other two groups. Since then, scientists have used Mozart and other classical music in various experiments on animals and humans, confirming similar results: Listening to classical music or learning to play an instrument leads to higher school grades and stronger spatial reasoning skills, reduces the risk of brain atrophy, and slows cognitive decline. The “Mozart effect” truly exists, said Kiminobu Sugaya, who has a doctorate in pharmacology and is a professor of medicine at the University of Central Florida College of Medicine and head of neuroscience at the Burnett School of Biomedical Sciences, during an interview with The Epoch Times. In experiments with local community residents, he found that when this type of classical music was played, “we saw a 50 percent increase in brain function.”
“The Mozart effect is clear evidence that you can alter the brain function and abnormalities with music,” Dr. Michael Trimble, professor emeritus of neurology and neuropsychiatry at the University College London Institute of Neurology and a Fellow of the Royal College of Physicians, told The Epoch Times. Sometimes, epilepsy is more difficult to control with medication, and using carefully selected and edited classical music to “train” the brains of epilepsy patients can normalize their brain waves and electroencephalographic abnormalities. A study published in Interdisciplinary Science Reviews in 2022 indicated that “to this date, K448 and K545 have remained the only anti-epileptic music selections that have been verified by repeated experiments.” The study also cited data from a 2020 meta-analysis, which found that “approximately 84 percent of participants in the reviewed studies exhibited significant reductions in epileptic brain activity while listening to Mozart’s K448.”
What the Brain Wants Regarding the effects on the human brain, the main difference between classical and pop music lies in “the complexity and structure,” Clara James, who has a doctorate in neuroscience and is a professor at the University of Applied Sciences and Arts in Geneva, Switzerland, and Privatdozent at the University of Geneva, told The Epoch Times. Before the age of 32, Ms. James was a professional violinist. Classical music of the common practice period (1600–1900) adheres to strict structural and harmonic rules. Even nonmusicians will notice a problem with its structure if a performer makes a minor mistake, Ms. James said. “It places a significant emphasis on proportion, balance, and harmony,” Ms. Yonetani added. In contrast, other forms of music may not strictly adhere to these structural rules. The human brain “likes the rules of music,” Dr. Trimble said. “There are certain musical sounds that are deeply embedded within the ability of our nervous system to be moved by music.” He emphasized that music contains natural rules and mathematical logic, especially classical music, wherein the connection to mathematics is robust. Therefore, it is universally recognized and accepted by the brain. Mozart developed a truly different style of music, moving away from the earlier Baroque period, Dr. Trimble noted. Mozart’s K448, which was the first piece used to investigate the brain effect and the impact of Mozart’s music on the brain in general, “may relate to spectrogrammatic considerations—in particular, the presence of lower harmonic frequencies.
“Classical and pop music differ in so many ways,” he continued. Pop music contains continual repetition around the same musical sequences, conveying information that is often vague and banal without the subtle development and variation that occurs in the progression of classical music. Ms. James pointed out that a typical classical music piece features a wide range of rhythms, with dynamics varying from extremely loud to very soft and extremely slow and fast sections—all seamlessly integrated. In comparison, a single pop music track has limited variability and maintains a regular rhythm. Besides, classical music pieces are relatively long, typically ranging from 20 to 25 minutes; some are even longer, such as Gustav Mahler’s works, which can last more than an hour. It carries rich information and allows the brain ample time to process it, much like slowly savoring an apple, as opposed to quickly consuming an apple-flavored gummy candy. Furthermore, the live sound volume at modern pop music concerts can be deafening, and the singers’ and fans’ behavior can be quite wild. “You can’t hear the music because people are screaming all the time,” Dr. Trimble said.
Contrary to classical music’s anxiety- and depression-reducing effects, some modern genres of rock music bring about excessive excitement and melancholy. When discussing young people’s preference for stimulating music, Dr. Trimble stated, “I do not believe that helps your emotional state.” Instead, he believes this music arouses anger and negative emotions. Certain modern genres of New Age music may also negatively affect emotions. In an older study, 144 participants of various ages listened to different music categories for 15 minutes, filling out the same questionnaire before and after listening. The results showed that classical music significantly reduced feelings of tension. Contrastingly, New Age music, while reducing feelings of tension and hostility, also lowered people’s mental clarity and vigor. Rock music not only significantly increased feelings of hostility, fatigue, sadness, and tension but also reduced people’s mental clarity and vigor and their feelings of caring and relaxation.
