I study music by myself. From the perspective of employment, the employment of music will be narrower than that of art, which is nothing more than teachers, orchestrals and soloists, while the employment of art is much wider, including various designs, ps and so on.
From the perspective of examination, there will be more colleges and universities that can apply for fine arts, and there is no need to find professional teachers to study. Music majors may need to find professional teachers to attend small classes alone. Music majors in colleges and universities are some music colleges, but the music majors in comprehensive universities are relatively not so good.
In terms of cost, art is undoubtedly burning money, and art costs a lot to buy tools, brushes, paper and classes; The cost of finding a teacher for music should not be underestimated. At present, the professional teachers in conservatories or universities are basically 1000 class, and some even have 2000 or 3000 classes. So we can consider the cost.
However, I think what you learn depends on what you are good at, and talent is very important to art.
