The Mozart Effect: Does Music Enhance Learning or Distract You?

Background music is often associated with supermarkets or beauty salons, but what about its presence in the classroom? This issue has attracted interest among scientists, and, it should be noted, not recently. There are many studies devoted to how music affects human mental abilities. Let's take a closer look at this topic.

In most studies concerning the relationship between music and learning, Mozart's name sounds like a leitmotif. However, it is worth considering whether he really embodies the genius who is capable of teaching through music.
The reason Mozart is often at the center of discussions is his outstanding musical legacy and influence on the development of classical music. His compositions have been the subject of numerous studies that have attempted to determine whether music can improve cognitive abilities or facilitate learning. However, it should not be forgotten that Mozart himself was not concerned with learning, and his music, although considered beautiful, is not a universal tool for enhancing mental abilities.
Thus, Mozart has become a symbol in this context, but his connection to the process of learning through music has no clear basis. This doesn't make him any less significant as a composer, but it does indicate that his music is not a panacea for learning.
There is a belief that classical music can influence academic performance. Some studies suggest that listening to works by composers such as Mozart or Bach can improve concentration and memory, which in turn has a positive effect on academic performance. However, the results are not always clear-cut, and the impact of music can vary depending on the individual characteristics of each person.
What happens if you ask students to listen to binaural beats, and what is this phenomenon? Binaural sounds are an audio technology that sends different frequencies to each ear, creating a spatial sound effect. These sound waves can influence brain activity, which can lead to various changes in state of consciousness and mood. Research shows that such music can help improve concentration and reduce stress levels. Therefore, if students listen to binaural beats while studying, it may help them focus and become more productive.
Is it possible that melody can serve as a kind of cue for our brain, contributing to more effective memorization of information?

Can Mozart improve our intellectual abilities?

Any discussion of an experiment that touches on the relationship between music, cognitive functions, and the educational process makes sense to begin with a mention of the Mozart effect, which regularly appears in scientific papers.

The Mozart effect suggests that listening to classical music can influence mental abilities. This term was coined in 1991, but it gained widespread popularity after the publication of a small scientific article in the journal Nature, written by psychologist Frances Rauscher from the University of California and her colleagues. In the article itself, the authors did not discuss the effect directly, but focused on describing a brief experiment involving college students. During the experiment, participants were played a ten-minute excerpt from one of Mozart's works, after which they completed a series of tests. Those who listened to the music demonstrated higher scores on tests of spatial abilities and were better at creating origami. It should be noted that this effect was short-lived and lasted no more than 15 minutes.

The article caused an incredible stir and, of course, was misinterpreted.

Under the influence of the media and creative marketers, there is a craze among parents for purchasing Mozart albums, which, in their opinion, can contribute to the intellectual development of their children. Although the original research on this issue has not received wide attention, situations often take a comical turn. For example, in 1998, the governor of Georgia became famous far beyond the state borders when he proposed allocating budget funds for the purchase of Mozart albums for all women who had just become mothers. He claimed that if babies listened to this "useful" music, their mental abilities would begin to develop from the first days of life.

Scientists also drew attention to a phenomenon known as the Mozart effect. They have conducted numerous studies trying to find out whether this effect really exists. In a recent meta-analysis with the intriguing title "The Mozart Effect vs. the Schmozart Effect," researchers reviewed 40 scientific publications on the topic and concluded that the effect lacks any serious scientific basis. Furthermore, Mozart cannot be considered the sole and undisputed leader in terms of his influence on brain activity. For example, it was found that the music of the British rock band Blur had a more positive effect on children.

This information was confirmed by Canadian researchers back in 1999. They conducted a series of experiments in which students were asked to listen to works by Mozart or Schubert for ten minutes, or spend this time in silence, after which they had to take a short test.

In another experiment, participants were asked to listen to either a short story by Stephen King, a Mozart piece, or simply sit in silence. The results showed that, firstly, students who listened to something did perform better on the tasks compared to those who did not listen to anything. Secondly, there was no significant difference in performance between works by Schubert, Mozart, and King's stories. The key factor was that the participants liked what they heard.

Various studies on this topic reveal a key idea: music has a significant impact on emotional state, engagement, mental health, and the ability to relax. The impact of musical accompaniment on work performance, in turn, varies depending on the individual characteristics of the listeners: for some, music can be a source of inspiration and energy, while for others, it can distract from tasks. Similar patterns likely also apply to the learning process: people who are in a good mood and enjoy listening to music are likely to demonstrate higher results.

It is important to note that in the educational process, instrumental classical music is most often used, since the presence of words can distract the listener. Researchers prefer such pieces due to their clear harmonic structure; they are distinguished by their smoothness and unobtrusive nature. In other words, such music is ideal as background accompaniment.

The Impact of Music on Students' Academic Achievement

What is the real effect of background music? This issue began to be actively studied back in the 1960s. For example, in 1967, a group of American scientists argued that listening to music during lectures and exams can contribute to improved student performance. Moreover, they noted that background melodies have a positive effect on the mood of not only students, but also teachers. However, the question arises: why haven't symphony orchestra recordings been used in educational institutions? The answer is that music's impact on learning is quite complex and multifaceted—as clearly confirmed by the results of three experiments presented below.

In 2012, a group of scientists from universities in Germany and France decided to study the impact of music on student performance. To do this, they conducted an experiment within a sports psychology course, involving 249 first- and second-year students. Participants were divided into two groups: both groups watched an hour-long video lecture with slides and instructor explanations, but the experimental group also listened to musical works by Mozart, Vivaldi, Tchaikovsky, Bach, and Beethoven as background music.

Both groups of students were asked to listen attentively to the material, as a quiz was scheduled after the lecture. Within 15 minutes of the lecture, the students completed a questionnaire and a test consisting of 25 multiple-choice questions. The results showed that participants in the experimental group performed significantly better than those in the control group. However, it should be noted that this is not solely due to the music's impact—the researchers emphasized that other factors, such as the students' prior experience and knowledge level, could have influenced the final scores. Ultimately, it was difficult to determine precisely how the music affected the students.

The researchers who conducted the experiment emphasized that the results could serve as a basis for future research in this area. They also confirmed that the learning environment significantly impacts learning outcomes.

Edgar Demetrio Tovar-Garcia, a PhD in economics and a lecturer at the Pan American University in Mexico, decided to add background music to his online economics lectures in early 2020. Initially, he used familiar lounge tunes, but soon discovered binaural music.

To understand the essence of this music, it is necessary to first understand the concept of binaural beats. When two different sounds, each with its own frequency, are heard simultaneously, our brain fills the "gap" between them, creating a third sound that does not actually exist. This effect is called a binaural beat. It can serve as a kind of stimulus, prompting the brain to change its own waves. There are four types of these waves - gamma, beta, alpha, and theta - and each of them manifests itself under certain conditions. For example, beta waves occur during moments of anxiety and excitement, while alpha waves are associated with relaxation and calm. Edgar's research demonstrated that this state of calm promotes improved concentration and, consequently, learning. Binaural music, in turn, aims to create a smooth transition between different states of consciousness.

The teacher, experimenting with new music and observing the students' reactions, noticed that their academic performance improved. Seeking to confirm his observations, he conducted a full-scale scientific experiment in 2021. His findings were presented at the XIV International Conference on Research in Higher Education.

The experiment involved 73 students divided into three groups. The first two groups, A and B, consisted of novices just beginning to explore microeconomics, while the third group had already studied international economics and had some knowledge of the subject. The professor decided to test the effects of binaural music in online classes, introducing it to different groups at different times. During the first trimester, students in Group A and an advanced group studying international economics listened to music, while in the second trimester, it was Group B. At the end of each class, the professor administered a test. The music played quietly, creating a background atmosphere so as not to distract the students from the learning process. The results were mixed: in Group A, academic performance declined after the music-assisted classes, while in Group B, on the contrary, it increased. The international economics group also showed an increase in academic performance, but it was less pronounced than in Group B. It is worth noting that at the start, Groups A and B, unlike the international economics group, were at the same level.

Based on a survey conducted among students, the instructor put forward a theory explaining the differences in results. One reason could be the quality of the internet connection: those who experienced problems with video playback developed a negative attitude towards the music. Another hypothesis is that the tests for Groups A and B were less difficult and included two-choice questions in the "True or False?" format, while the more advanced group studying international economics were offered questions with five answer options. Tovar-Garcia suggested that beginners could answer the questions randomly, which could have caused the differences in the results of the two similar groups.

Overall, as the instructor emphasized, the participants enjoyed the music: it promoted relaxation and created an atmosphere of calm. There were even those who completely forgot about it during the lesson. However, not everyone enjoyed the musical accompaniment: some considered the extraneous sounds distracting, others preferred a more cheerful melody or their own, and still others found the recording's volume excessive.

Psychologists from Baylor University in the United States conducted a rather unusual study involving 50 college students, ranging in age from 18 to 33. The experiment took place in a specially equipped sleep lab.

The participants spent two nights in the lab. On the first night, they adapted to the new conditions. Before the second night, they were presented with a 30-minute interactive lecture on macroeconomics, during which they were also given practice questions. Compositions by Vivaldi, Beethoven, and Chopin played in the background.

After this, the participants went to bed, and the researchers waited for them to fall into deep sleep. At this point, they were silently played either the same music that played during the lecture or white noise for 15 minutes. The students' condition was monitored using specialized devices.

Why did such difficulties arise? Scientists decided to investigate the targeted memory reactivation method—an approach that helps the brain transfer information from working memory to long-term memory. This process occurs through the interaction of two stimuli: the information itself and a cue for the brain. Such a cue can be anything related to the context in which the new information was acquired. For example, it could be an object in the classroom environment that the listener paid attention to during the lecture. In this case, the background music playing during the lecture served as this cue.

In the morning, the study participants took a test related to the topic they had studied the previous day. This test included questions requiring the application of acquired knowledge. The results showed that the group that had been played music during sleep performed better. Specifically, more participants in this group achieved the minimum required score and also performed better on more difficult tasks. Nine months later, the testing was repeated, but only 27 people agreed to participate. As it turned out, both groups were unable to recall the studied material after a long period of time.

Thus, the method of targeted memory reactivation using music was effective for retrieving information the next day. However, for new information to be retained in long-term memory, it is necessary to additionally repeat the material, since without this it will not be transferred.

The researchers who conducted the experiment emphasized several key conditions: the music used during the study should not contain lyrics, and also should be familiar to the participants. The scientists decided to deepen their research and hypothesized that if the music is played not just once, but on an ongoing basis, the duration of the effect may increase.

What implications does this have for teachers and students?

Summarizing the data from various studies, we can come to an obvious conclusion: the use of music during classes is possible, but subject to certain conditions. It is important to select an appropriate piece of music, ensure high-quality sound, control the volume, and create a comfortable atmosphere for students. However, this would be more of an experimental approach than a proven method with proven effectiveness.

Listening to music while studying is perfectly acceptable, and many students report that they actually enjoy it. A lecturer from the University of Wollongong in Australia, based on the research he analyzed, explains that music can have a positive effect under certain conditions:

it brings you joy;
the music is of a moderate tempo and is played quietly enough;
When listening to music, it is worth choosing compositions with a small amount of lyrics. For example, hip-hop can be distracting due to its rich vocabulary.
You are not an introvert, since extraneous sounds most likely do not bother you, and may not even irritate you.

In general, music currently serves only as a means of creating a positive mood and a comfortable environment, including classrooms. However, its effect on cognitive function during learning remains a matter of debate.
