Music activates many regions of the brain, including auditory, motor and limbic (associated with emotions). Such widespread activation of brain explains many beneficial emotional and cognitive music effects. The idea that music makes you smarter received considerable attention from scientists and the media. Listening to music or playing an instrument can actually make you learn better. And research confirms this by showing that music has the power to enhance some kinds of higher brain function: literacy skill, spatial-temporal reasoning, mathematical abilities (even children with attention deficit/hyperactivity disorder could benefit in mathematics tests from listening to music beforehand), emotional intelligence, and recall of autobiographical and episodic information. The power of music to affect memory is quite intriguing. Earlier it has been thought that listening to classical music, particularly Mozart, enhances performance on cognitive tests. However, there are findings that show that listening to any personally enjoyable music has positive effects on cognition. Listening to music also facilitates the recall of information. Researchers have shown that certain types of music are great keys for recalling memories. Information learned while listening to a particular song can often be recalled simply by “playing” the songs mentally. Musical training has even better effect than just listening to classical music. Activities, such as playing an instrument or singing, involve both sides of the brain at the same time. The information being studied activates the left brain while the music activates the right brain. The simultaneous left and right brain action causes the brain to be more capable of processing information, hence maximizing learning and retention of information. There is clear evidence that children who take music lessons develop a better memory compared with children who have no musical training. Moreover, music that is easy to listen to or relaxing classics improves the duration and intensity of concentration in all age groups and ability levels. It's not clear what type of music is better, or what kind of musical structure produces the best results, but many studies have shown significant effects.
