Making music is not only about feeling joy and having fun: a recent study by the Brain and Creativity Institute at the University of Southern California demostrated that music training impacts brain structure. Children who receive even a few years of music lessons have brains that mature faster. Music training during childhood can also benefit language acquisition, speech perception and the readiness to read.
Here is an exciting article from PBS Parents about the benefits of music education:
Benefits of Music
There is no substitute for music. Music enriches the inner self: it nourishes the love of learning, puts us in touch with our feelings and facilitates growth in motivation, self-discipline, time management and social skills. We do not play an instrument or sing to get to the end of the piece; we do it to make music.
Music helps us get away from our daily routine and relate to the wider world. It teaches cooperation and teamwork and encourages cultural awareness: music reflects the history, literature, and culture of a country in song texts and musical styles. In addition, song lyrics offer a unique means of reinforcing speaking, listening, reading and writing skills.
