Early musical training helps develop areas of the brain involved in language and reasoning. It is thought that brain development continues for many years after birth. Recent studies have clearly indicated that musical training physically develops the part of the left side of the brain known to be involved with processing language and can actually wire the brain's circuits in specific ways. Linking familiar songs to new information can also help imprint information on young minds.
There is also a causal link between music and spatial intelligence (the ability to perceive the world accurately and to form mental pictures of things). This kind of intelligence, by which one can visualize various elements that should go together, is critical to the sort of thinking necessary for everything from solving advanced mathematics problems to being able to pack a book-bag with everything that will be needed for the day.
Students of the arts learn to think creatively and to solve problems by imagining various solutions and by rejecting outdated rules and assumptions. Questions about the arts do not have only one right answer.
Recent studies show that students who study the arts are more successful on standardized tests such as the SAT. They also achieve higher grades in high school.
Music study develops skills that are necessary in the workplace. It focuses on "doing," as opposed to observing, and teaches students how to perform, literally, anywhere in the world. Employers are looking for multi-dimensional workers with the sort of flexible and supple intellects that music education helps to create. In the music classroom, students can also learn to better communicate and cooperate with one another.
Music performance teaches young people to conquer fear and to take risks. A little anxiety is a good thing and is something that will occur often in life. Dealing with it early and often makes it less of a problem later. Risk-taking is essential if a child is to fully develop his or her potential.
