Through music, children build up spatial analysis. They will take the repetition of the measures in a music piece and formulate a mental image that makes sense. This type of learning accentuates the ability to reason out a situation.
Music helps children with verbal skills, especially lyrical music. Through the presence of recurring poetry and the use of a bigger vocabulary, children learn to speak and write better.
Children learn to sing, develop an ear for music and also learn to identify musical notes correctly.
Music makes learning math easier. The rhythm of the music composition allows a child to learn counting and timing. Learning timing is also essential in time management, and consequently, responsibility in self-management.
Music in early education fosters the ability to develop proprioception and/or kinesthesia, which translates to body awareness and tactile intelligence.
As you can see, there are many benefits to introducing music to children early on in education. Music should not be cut from school programs or forbidden from a child just because it isn't thought of as a way to put food on the table. It can make your child smarter in whatever he/she does.
