It is hard to deny that It is not necessary to learn music in schools because it is time-consuming. And such effects to some people to generate the opinion that children don't need to learn music, as It is not as important as other lessons. However, such a statement suffers from both logical and factual fallacies and should be examined meticulously. As far as mental health and learning ability, I strongly hold that music is as important as other subjects, especially those at the preschool level.
