Which is better to learn, art or musical instruments?

There is no way to compare the two, it depends on a person's qualifications, and if they are talented in any area, they will learn especially fast. If both are similar, I personally think that musical instruments are slightly easier, because what keys are pressed is a mechanical movement, and when you are skillful, you can do it. Art is a very difficult art. I majored in art in school, and many of my classmates graduated after three years with ugly drawings. Musical instruments are different, always practicing a piece of music every day, it does not take many days to practice proficiency. The difference between what sounds beautiful to an outsider and what doesn't is not very big.
