...this poem by Emily Dickinson appears in the introduction of Kamilla Denman's essay "Emily Dickinson's Volcanic Punctuation", which I found tonight after watching a PBS docudrama on the 1883 eruption of the volcano Krakatoa and the resulting tsunami.
In the essay Denman says "to look at Dickinson's punctuation purely as a disruption of language, then, is to miss this musical dimension, where the semantic and rhythmic disruptions are smoothed through an implied melody". An implied melody. I like that. Hmm --
