Art and music are very creative and vast subjects. However it is not necessary that everyone shall be a good musician or good at art. Hence music and art as compulsory subjects sound to be wrong.
It is nice if schools have infrastructure facilities to teach art and music. Those who have a deep aptitude for art and music can take-up those subjects and even master those for that matter. At the same time making subjects of music and art as compulsory, may take a considerable amount of time and energy of students which otherwise he or she can devote towards main subjects like, Physics, Chemistry, Mathematics, etc. Devoting time to main subjects is a paramount importance for success in the examinations and future career. Hence and art and music may be optional but not compulsory.
Music and Art shall be highly beneficial to those who have an aptitude of learning art and music and aspirant musicians and artists.
Subject of Art and Music is very creative and one must learn it. Nevertheless the world is not composed of artists and musicians only, apart from this, everyone may not become artist and musician nor art and music form a base or constitute the foundation of academia. In conclusion art and music are purely subjects that must be indulged in for creativity and entertainment to those who opt for and should not be made compulsory for all students
