Effects of Music

Research into the effects of music on behavior, intelligence, learning, pain tolerance and health have generated a number of interesting findings.

Music, Intelligence and Learning:
According to the Association for Psychological Science, intelligence test scores grew higher in children who took lessons in keyboarding or singing. In another study, boys between the ages of 6 and 15 who took music lessons scored higher on tests of verbal memory than a control group of students without musical training.

Music and Pain Reduction:
Researchers found that patients who listened to harp, piano, synthesizer, orchestra or slow jazz experienced less post-surgical pain than those who did not.

Music Therapy and Autism:
Music therapy is particularly helpful for autistic students, who have difficulty interacting with classmates and teachers and become agitated in noisy, changeable environments. Autistic students respond very well to music therapy, which can be used to help them remain calm under stress and socialize more effectively. In addition, many autistic children have spectacular music skills.

Music and Plant Health:
Experiments conducted by Dorothy Retallack to learn about music's effects on plants are described in her 1973 book The Sound of Music and Plants. Retallack played rock music (Jimi Hendrix, Led Zeppelin and Vanilla Fudge) for one group of plants and jazz for another. When two weeks had passed, the jazz plants were healthy and bent toward the radio. The rock music plants grew very tall and droopy, with faded blooms, and most had died within 16 days.

Retallack tried other types of music, including country, to which the plants showed no reaction, and modern (discordant) classical music, which caused the plants to bend away from the speaker. The plants seemed to “like” Bach and North Indian sitar and tabla music.

Other people have conducted similar experiments, and some claim to have achieved similar results. However, Retallack has been criticized for using unscientific methods in her experiments.

Most music studies to date have used small sample sizes and some have not controlled for confounding variables, so although these findings are compelling, more research is required. However, given that many studies have generated similar results for certain types of music, the psychology of music is certainly worthy of further exploration.
