Actually, Brian ... you don't have this quite right. Pomp and Circumstance is the larger work; or rather, it's the name given to a grouping of marches. And the one that most are familiar with, because it's used at graduations, is March No. 1 in D major. The official title of that particular march is Pomp and Circumstance March No. 1 in D major (and NOT March No. 1 in D major from Pomp and Circumstance.) Sometimes you'll hear orchestras do several of these marches together in a concert, but rarely would you hear all five of them; and most often you'll just hear them performed individually as each is its own work in and of itself. It's not like Pomp and Circumstance is a larger work, like a symphony, and one the marches is an equivalent to one of the movements in that larger work. Put it a different way ... a symphony would be like a book, one large book, with one story start to finish, and the chapters in that book would be like the movements in a symphony; Pomp and Circumstance would be like a large book of stories; each story is separate from the next ... different plot, different characters from one to the next. The marches grouped under the title Pomp and Circumstance would be like these individual stories in this larger collection. And I'm sure that's all clear as mud. But I tried.
