Like stanza one, this stanza opens with a flat, matter-of-fact statement that recapitulates the opening line -
Ever since she died/she can’t stop dying. The enigmatic nature of this statement is now clear to us in the overall context of the poem.
We realise it is within the poet’s consciousness that she
can’t stop dying– his psyche is perpetually tortured by this overwhelming experience.
A further simple statement follows as he begins to reach his conclusion -
She makes me/her elegy.
An elegy is song or poem associated with death. His grief is so raw, so profound and all-consuming, he identifies entirely with it to the exclusion of all else - he has become a physical embodiment of a lament.
He now extends the notion of himself as the product of a literary imagination when he describes himself as a
walking masterpiece/a true fiction of the ugliness of death.
masterpiece is used satirically to convey how successful his transformation into an embodiment of death, despair and despondency has been.
true fiction conveys jointly the idea of him being a (reversed) literary representation of death’s horror or
true conveys the completeness of this transformation.
The final simple line sums up one of the central ideas in the poem -
I am her sad music.
This hopelessly pessimistic note again emphasises the ceaseless, all-encompassing nature of the grief and sorrow that consume him and pervade every aspect of his consciousness.
