I’ve done many abstract works in the past as well as traditional art BTW.
Abstract art is different from figurative, because it doesn’t depict real things. it can use shapes, colour, composition and more.
what i don’t understand is why here all think to science,maths, cogitation when thinking to abstract art . abstrat art relies more often in emotion than common people can think. color is emotion, composition too. sure, ther have been alot of artists which used a cognitive and scientific approach, but no one stops artists from evoking emotions.
Picasso’s works were not abstract, basically. they were modern. a different vision of nature and thus often based on it. he then brought natural shapes to extreme transforming them in bunch of elements in some work, but saying he was an abstract artists is uncorrect.
Kandinsky. he was abstract. he used shapes, of every kind to suggest emotion, music, and more. Mondrian. here another abstract. Miro is an abstract artist and so on.
abstract art isn’t popular because its way more difficult for common people to understand what’s under the hood. not that they always understand traditional art too. more often, simply, they appreciate and recognize figures and things they usually see in the real world.
that’s why a great abstract artists always come from a figurative experience at least. figures are more difficult to draw correctly because they have inherent rules to which they obey :volume in perspective, light, texture and more so an artist must be very well trained to make an excellent figurative work.
but since a painting is a flat surface, covered wiith paint, figurative rules had to be broken at a certain point, even because human vision isn’t the only way to represent things, and this is were modern art comes. a different vision about nature and world.
then, to go to the extreme of this process, even figuration was abandoned in favour of pure emotion, colour, abstract shapes.
Even if its more difficult to understand, in the hands of good artists even abstract can be great art and in certain cases can be superior to figurative art.
