premise: A man in gray and black is playing a black acoustic guitar with a slightly shorter woman who is wearing pink and playing a violin.

explanation_2: The fact that a man and shorter woman playing violin doesn't imply that they are wife and husband.
explanation_3: We have no idea if they are a wife and husband, they could be anyone.
