I answered a question similar to this here:
brainly.com/question/8880255I think the thinker who addressed the questions you're asking the best was Immanuel Kant. Kant believed firmly that there are universal values all rational beings will agree upon, if we think about them thoroughly enough. That doesn't mean there won't be a wide range of variation between cultures or between different time periods. But in whatever culture, in whatever time, there will be a beautifulness seen in the human form, for instance. That might vary between cultures and over time. Plump persons may be seen as "beautiful" in the art of one period while thin people are considered beautiful in another era. Or the styles of cosmetics and hair/clothing will change. But overall there is a desire for beautiful expression of the human form in the art of all cultures and times.
The ancient philosopher Plato thought in ways like this too -- that there is an ideal of beauty, of truth, etc, that exists out there in the universe somehow. The attempts we make to express it are all trying to grasp that ultimate form of beauty somehow.
1: I like Classical, and Romantic styles. I like the classical style because of the way mozart and haydn made their music. Grand, kind of shallow in terms of emotion, and the abundance of it being played in G major xD. I like the romantic style because of the emotion. The use of dissonance and chromatic movements.
2: Modern technology has lead to things like smooth jazz, vaporwave, and EDM. Jazz originated from people changing the parts of marching music. MOdern technology is doing the same things, but using computers and electronic sounds, leading to a larger variety of music. Modern technology will affect music inv the future the same way it has already.
