Gentility

Poetry seems to be belong to a genteel sphere of life, sociologically speaking. Yet it is elemental, passionate, basic.

Every genre of music contains everything, potentially at least. Humor, passion, tenderness, bombast, despair, cloying sweetness, cliché.

So one view would be that poetry is classical music. It contains all of that, but to people who don't belong sociologically to the group that listens, it all gets collapsed into the category of the genteel.
