Compounds Constitute is a compilation of poetry in the short-form. The book is a rewrite of the compilation 'Compound Constitute', one of three compilations, which were rough self-published books for family & friends. It covers the themes that run throughout all of Leigh's work, nature, landscapes, seasons, elements, metaphysical, astronomy, time, cityscapes, technology, transport, perceptions, philosophies and human interactions. â€˜Compound Constituteâ€™ was Leigh's first compilation, it was assembled into two parts, the first part, was organised into chapters based on the themes of the five forms of matter, (air/gas, earth/solid, water/liquid, fire/plasma & ether/life). While the second part, was themed on the circle, which represents matter/elements being bound together into compounds, (time, seasons, landscapes, philosophy, interactions & outcomes). Leigh's poems are predominately a composition of a particular moment or instant, like a photo or painting of a scene or a feeling in the moment it's felt.
