I have a spherically tapered cylinder that I'm trying to apply smooth shading to, partially. (Sorry for the terrible description, picture below)

I'm trying to apply smooth shading to vertical rings in the picture - I like the defined edges that run along the x-axis. I tried selecting only those rings in edit mode and applying smooth vertex, but that didn't appear to do anything. Will, I have to put in loop cuts for each x-axis line, then add an edge split with smooth shading to get my desired effect?
