Elegant art and abstract art

You can find elegant women, fashions, clothes, furniture, buildings, houses, manners and behaviors and even mathematics formulas, physics equations and some movements in sports. But 'elegant' paintings are seldom heard. Elegance makes or elegant things make people feel pleasant. There are many paintings which make people feel pleasant but most of them are not called or regarded as 'elegant'. Van Gogh's paintings are far from elegant but they make people feel pleasant but not through elegance. Picasso's paintings are can be said as 'elegant' in a way but many people may not agree. Mona Lisa (Joconda) looks like an elegant woman but this Da Vinci's painting is not necessarily elegant. We seldom heard elegant music either.

This is may be because paintings and music are pure arts and have no practical functions while the other things like women, fashions, clothes, furniture, buildings, houses, manners, behaviors and some movements in sports have some practical functions. Mathematics formulas are physics equations can be regarded as having functions when they are used. Elegant mathematics formulas and physics equations solve complicated problems or analyze complicated relations in unexpectedly simple ways. This may be a hint to answer the question - what are pure arts ?

The adjective 'elegant' is used often equally as 'beautiful'. Beautiful things make people pleasant. Ugly things usually make people feel unpleasant. We seldom heard 'ugly' paintings and 'ugly' music either.

Abstract paintings do not make people unpleasant but may make people puzzled, uncomfortable and even fearful or unsafe (the word which I found recently). Fearful or unsafe feeling comes from the lack of something and you cannot fill it since you do not know what is missing. This contrasts with elegance. Elegance is fulfilled, well balanced, no sense of lacking. See below. 

According to wiki (https://en.wikipedia.org/wiki/Minimalism#Less_is_more_.28architecture.29)

"
The concept of minimalist architecture is to strip everything down to its essential quality and achieve simplicity. The idea is not completely without ornamentation, but that all parts, details, and joinery are considered as reduced to a stage where no one can remove anything further to improve the design.
