Learning an instrument causes changes in the plasticity of the brain. There is growing evidence that musicians have structurally and functionally different brains compared to non-musicians - parts of the brain that controls hearing, memory and the hands all become more active in people who learn instruments.
Musicians who regularly play an instrument can increase their IQ by as much as seven points. This counts for both children and adults.
Musicians have a much easier time identifying the emotional state of a person solely based on their voice. When you play an instrument, you learn about tones and scores and this increases your ability to store audio information. This makes it easier to identify exactly what others are feeling based on the tone of their voice - Empathy, disappointment, etc..
