Warmth is a powerful component to giving life to words. The poetic language when articulated by human voice is a music spoken in meter, with each pitch fluctuating to the word's content and meaning. There also exists, however, a set of words which are musical simply in the sound of their utterance. In Yeat's poem, words of this type abound, with rhythmic and lilting attributes. The entire poem is an alternation between fortissimo and pianissimo, between seamless and broken, and imparts a musicality which is independent of meaning or interpretation.
Lyrical words are simply delicious to hear.
Amidst brilliant sights and sounds, smell is left uncovered. Through fragrances a poet can weave enticing images which set a stark emotional backdrop. Truly, the magic of Yeat's language is its perfume. An insatiable essence permeates Yeat's poem, and in the passing of its reading, the fragrance of his language whets a hunger for something more substantial. Yeats suffers the same hunger for the realization of his dream isle.
