I am always interested in the ways of scoring the sound of the poem, especially a poem with long lines. Spaces within a line, double colons, slashes, are indications of pause, of breath, of urgency, they are not metrically exact as in a musical notation but they serve (I hope) to make the reader think about the sound of the poem-just as traffic symbols, when driving, make us almost unconsciously aware of a steep hill, an intersection, an icy bridge etc. Poets have used such indicators long before modernism-Dickinson's dashes and capitals are one example. Contemporary composers have also expanded on classical notation with new, self-invented markings. You want to find a way that is not random or chaotic but allows for various renderings of a line, a punctuation of the imagination.
