Myth or Fact: Does classical music really make my baby smarter?

Much has been said about letting babies listen to Mozart and Bach so that they grow up to be intelligent. This article by Dr. Louddie Castillo explains what classical music and music training has to do with a child's brain development.

Music seems to have a strong effect on a person’s behavior and mental state. A cranky baby can easily be pacified by a soothing lullaby, a stressed teenager can find solace in listening to her song list in Spotify, and an anxious adult can find comfort with a classical chorale. Much has been said about letting babies listen to Mozart and Bach so that they grow up to be intelligent. Is this true, and if so, what does classical music in particular have to do with a baby’s brain development?

A baby’s brain rapidly develops within the first few years of life, with a set of billions of brain cells called neurons forming connections with each other. As babies explore their environment, certain connections in the brain become stronger, i.e. a baby who grows up listening to her mother singing will easily respond to the songs her mother sings, and will eventually be able to sing along with her. In fact, children who thrive listening to music actually showed structural music-related changes in the connections in the brain. 

As some of these classical music pathways or connections are shared by certain thinking processes, these music pathways therefore affect the way we think. This was explored in a small study in 1993 looking at college students who listened to Mozart sonata while taking an IQ test. The study concluded that listening to classical music seems to transiently improve spatial reasoning for a short time. This is in contrast to learning to play an instrument, which may have a more sustained effect on certain thinking processes. A child with good spatial reasoning or ability can do spatial tasks more quickly, such as solving a Rubik’s cube or forming a jigsaw puzzle. 

Although this does not exactly equate to higher IQ, research has suggested that music training also enhances nonmusical cognitive and executive function skills. Learning to play an instrument engages three components of executive function: inhibition, working memory, and cognitive flexibility. These executive function skills are essential core skills in learning and behavior. As these pathways are primed and ready to be used, it facilitates learning.  Additionally, researchers suggest that new brain pathways are formed with music training. 

What makes classical music different from other types of music? Classical music, which most people associate with works by Mozart, Bach, and Beethoven for example, has a more complex musical structure. It is this characteristic that experts attribute the priming of the brain to solve spatial problems faster. Babies, as early as in the womb, respond to classical music. But in general, listening to any kind of music creates stronger music-related connections in the brain.

Activities such as playing music for your baby, singing to your baby, or signing with your child help nurture love of music. Furthermore, starting music lessons early and incorporating music in your child’s learning will significantly impact a child’s coordination and creativity.
