What is the author's tone in the poetry collection, Notes on the Assemblage?

Herrera's mood and tone varies, and it is evoked by language. The various elegies (i.e. tributes to the dead) are marked by qualities of reverence, respect, and grief; the dialogue poems (i.e. poems in which ideas are communicated through conversation, rather than narration) take on a completely different, more accessible, characterized tone; and the more overtly political poems take on tonal qualities that reflect the violence (physical, moral, economic) they are evoking.
