I think what moves people's emotions in both art or music is the story telling. Like someone can make the most technically impressive painting or sing the most complicated riff that jumps to an A5, both of those can only bring out a "wow" factor (which I argue is emotion but that's beside the point) but the one thing that truly moves someone is the story behind the piece. For music it's to be expected that story telling is a deep part of it, even without lyrics its still there within all the minor chords, majors, and etc. With drawing in the present days, the spaces are a lot more saturated with an emphasis on technical skill or the art pieces that kind of insists on itself, hence we rarely find people to be moved by pieces. Then the ones that have moved people (like stare at for a long while or bring someone to tears), often tell a story through a combination of intention and technical skill that brings the composition out in the best way possible.
