Yeats, the Master of Sound is such a study. The author traces Irish speech rhythms back to Gaelic and, in this context, explains what Irish poets owe to their local accent--Heaney, in particular, has acknowledged such a debt. Using the American poet Robert Frost's concept of the "sound of sense" as a key, Dr. Devine explores the rhythms of Anglo-Irish poetry and their stating of a formalized emotion through such traditions as the amhrán (Irish song metre) and the ancient method of singing known as sean-nós. Yeats was to build on these connected influences, adding a theatrically defiant tone to patterns of assonance and rhyme to attain an "elaborate rhythm"--again a concept and practice derived from the Gaelic. This book shows how the Irish speaking voice is in thrall to a language which has endured for over 2,000 years and which, by its shaping of the rhythms of that voice, continues to influence those of the island's poets who write in English today.
