If I were forced to only listen to one genre for the rest of my life it would be jazz.
Jazz is the only music that has never failed in keeping elevated levels of happiness in my system. It has become my drug of choice recently; being an au natural auditory seretonin booster. Personally, I flock to music that offers no lyrics, or lyrics in another language, because I find that vocals and lyrics distract from the music itself. The only thing you have when you listen to the majority of jazz is the arrangement, the music, and yourself.
So if jazz can have this effect on me, does it have the same effect on other people?
After looking around the internet quite a bit, I did find multiple blog posts about how jazz enhanced peoples’ moods. Some posts even stated that jazz and classical music shuts off a part of the brain that worries too much, but I have yet to find a scientific study claiming this although I wouldn’t doubt it’s validity. It also seems that the complexity of jazz music, just as classical music, can effect the brain in positive ways and increase memorization. One blog even suggested that our brains are secretly counting as the the music is playing, thus firing up brain cells that we normally don’t use. Regardless of what is true or not, its pretty obvious that jazz and other genres have a positive effect on the brain.
A study done on stroke recovery victims in Finland found that patients who listened to 2 or more hours of music a day (pop, jazz, folk, and classical) improved their verbal memory by 60% in three months over the patients who were not exposed to music. Positive mood and increased cognitive skills were also reported. Their findings proved that music therapy is an essential part to the recovery of all types of patients.

The brains of jazz musicians themselves vastly change when playing improvised music over a memorized, composed piece. Two scientists from John Hopkins University, Dr. Charles J. Limb and Dr. Allen R. Braun, used an MRI and a specially made keyboard that would not interfere with the MRI’s magnets, to study jazz musicians. The MRI showed that when they were playing a piece of improvised music versus memorized music there was a “disassociated frontal activity state” and the dorsolateral prefrontal cortex, which is a large portion of the front of the brain that extends to the sides, actually slowed down. What does this part of your brain do exactly? It is linked to “planned actions and self-censoring” which ultimately leads to lowered inhibitions. This type of lowered inhibition and creativity is vital to human development, artists and non-artists alike. Dr. Limb explains that “What we think is happening is when you’re telling your own musical story, you’re shutting down impulses that might impede the flow of novel ideas.” Its vital to every human because every day we are improvising- from the conversations we have to the small tasks we perform every day.
Here’s a nice short video of their study:

I’m no doctor or jazz musician, but I think it would be safe to say that in whatever way jazz music shuts off certain areas of the brain, it is also leads to elevated levels of euphoria. It would make sense that turning off your inhibitions turns away negative thoughts and amps up your creativity, thus boosting those happy cells in your brain.
Enjoy listening.
