Obviously you can be as emotive on a guitar, but it doesn't come as naturally as it does with wind instruments based on my thinking.

Going more back to the original topic, I wonder if you were thinking that the cello and violin were more expressive because of their association with classical music, which is conventionally seen as one of the "moodier" genres.
