Like the wonderful melancholic melody, words, and harmonies of a song in a minor key sad paintings have their own kind of special beauty for me.
I especially love the exquisite, gentle sadness portrayed in the works of Raphael Soyer, George Tooker, and Edward Hooper.
The people in Raphael Soyers painting always seem like there are feeling a quiet kind of sad:

George Tooker’s paintings cry of sad people that are lonely and alienated even in group

Edward Hoppers people seem to me to be content with their quiet lonely sadness:
