We all know intuitively that sex, drugs and rock ‘n’ roll provides pleasure in most humans. But why?
A study released on Wednesday suggests that the euphoria you experience while enjoying music is triggered by the same brain chemical system that gives humans pleasurable feelings associated with sex and recreational drugs.
The landmark research from McGill University in Montreal is the first study to demonstrate that the opioid system in human brains is directly involved in musical enjoyment.

“This is the first demonstration that the brain’s own opioids are directly involved in musical pleasure,” says cognitive psychologist Daniel Levitin, senior author of the paper.
While previous work by Levitin’s lab and others had used neuroimaging to map areas of the brain that are active during moments of musical pleasure, scientists were able only to infer the involvement of the opioid system.
“The findings, themselves, were what we hypothesized,” Levitin said. “But the anecdotes — the impressions our participants shared with us after the experiment — were fascinating. One said: ‘I know this is my favorite song but it doesn’t feel like it usually does.’ Another: ‘It sounds pretty, but it’s not doing anything for me.’ ”

Although the neural underpinnings of music cognition have been widely studied in the last 15 years, the study says, relatively little is known about the neurochemical processes underlying musical pleasure. Preliminary studies have shown that music listening and performing modulate levels of serotonin, epinepherine, dopamine, oxytocin, and prolactin. Music can reliably induce feelings of pleasure, and indeed, people consistently rank music as among the top ten things in their lives that bring pleasure, above money, food and art.
Aside from the strong findings, the study also suggests that musical therapy may be much more effective than previously known. And musical therapy is not a “new-wave” form of treatment.
According to the American Musical Therapy Association:
The idea of music as a healing influence which could affect health and behavior is as least as old as the writings of Aristotle and Plato. The 20th century discipline began after World War I and World War II when community musicians of all types, both amateur and professional, went to Veterans hospitals around the country to play for the thousands of veterans suffering both physical and emotional trauma from the wars. The patients’ notable physical and emotional responses to music led the doctors and nurses to request the hiring of musicians by the hospitals. It was soon evident that the hospital musicians needed some prior training before entering the facility and so the demand grew for a college curriculum. The first music therapy degree program in the world, founded at Michigan State University in 1944, celebrated its 50th anniversary in 1994. The American Music Therapy Association was founded in 1998 as a union of the National Association for Music Therapy and the American Association for Music therapy.
The McGill University study proved to be “the most involved, difficult and Sisyphean task our lab has undertaken in 20 years of research,” according to Levitin. “Anytime you give prescription drugs to college students who don’t need them for health reasons, you have to be very careful to ensure against any possible ill effects.”
Music’s universality and its ability to deeply affect emotions suggest an evolutionary origin, and the new findings “add to the growing body of evidence for the evolutionary biological substrates of music,” the researchers write.
