Matthew Welton is a poet enchanted by form and process. Many of the Number Poems abide by subtle patterns or constraints, creating symmetries in the arrangement of sentences, lines, words, or metrical feet. As with good architecture, however, Welton’s rules and methods resist exclamation; rather, they are the framework upon which are established localised ambiances, be they of warmth or dazzlement, the home or the dream. Other sequences, such as the mind-altering ‘Melodies for the meanwhile’, begin with a palette of words and images and recombine them kaleidoscopically. By adding layers of colour and sound, Welton composes a modulating sensory wave. Even in silence, we do not so much read these poems as perform them.
