"I'll see you after Mozart dies," I said cheerfully to my traveling companions, as we all headed off to our separate seats in Davies to hear the Requiem he died in the middle of composing. Of. (It feels like there's a preposition missing somewhere in that sentence.)
Speaking purely professionally, I can tell you that there is nothing whatever wrong with the grammar of that sentence. Here's a derivational sequence:
He died in the middle of composing the Requiem is an independent clause. To make it a dependent, subordinate clause, you attach it to a sentence that has the same direct object: . . . to hear the Requiem. To do the attachment, you move the words the Requiem to the front of the (now subordinate) clause: the Requiem he died in the middle of composing. And it leaves behind he died in the middle of composing [ ].
There was no preposition before you moved it; there doesn't need to be a preposition after you move it. Really, it's fine.
no subject
