Found a mechanism that makes the brain remember obsessive music

Each of us at least once in our lives for sureI came across a phenomenon when lines from an obsessive melody suddenly pop up in my memory and for a long time interfere with my focus on the job. The notes, tempo and words are repeated over and over in the head, even if the melody is not at all our favorite. Most often, such musical accompaniment is found in commercials or music in the “pop” style, but, of course, exceptions to the rules are not uncommon. In any case, scientists were able to analyze 80 thousand chords and determine the mechanism that “makes” the brain to remember the obsessive music that a person could hear somewhere.

Pop style implies light, melodic music that most people can enjoy.

Why is the pop music style so popular?

Why is pop music so popular? According to a study published in the journal Current Biology, in order to answer this age-old question, scientists analyzed 80,000 chords from the 745 pop songs that were on the Billboard chart, and came to the unexpected conclusion that almost all pops -Songs combine elements of uncertainty and surprise.

In the course of their research, scientists dismantledsongs, cleansing them of melody and rhythm and leaving only chords. The task of 39 volunteers was to listen to 1039 chords in 30 sequences of 745 popular songs and then evaluate the audience. At the same time, in a separate experiment, 40 people were observed listening to the same chords, and their reaction in the brain was monitored with the help of special instruments and scanners.

Music arouses pleasure, provoking the listener to constantly generate and encourage the expectations of a particular rhythm that is gradually unfolding in time

As a result of experiments, it turned out thatmusical compositions are able to activate the amygdala, hippocampus and auditory cortex, which help us process emotions, sounds, learn and acquire memories. At the same time, the adjacent nucleus, which was previously associated with joy and enjoyment of music, was activated only when listeners were faced with manifestations of insecurity in songs or with unfamiliar chords. An unusual experiment led scientists to the conclusion that we like songs in which we expect to hear a certain chord, but unexpectedly for us we meet another one that is different from what was expected.

Scientists are convinced that the combination of computer modeling and brain visualization can provide an understanding of why we like this or that musical composition.

Researchers suggest that the resultsoriginal research will find application in various fields, ranging from the creation of music by artificial intelligence and ending with the help of songwriters in writing music, in improving algorithms and even in predicting future musical trends.
