The development of Song Ci in the latter part of the Northern Song Dynasty reflected the trend of moving closer to poetry,and Su Shi has completely broken the boundaries between poetry and Ci-poetry:the mergence of poetry and Ci-poetry on the theme was realized;the boundary of poetry and Ci-poetry on style was disappearing gradually,and the relation of text and music was separating gradually.
苏词打破了诗词之间的界限,体现出词体不断向传统诗歌靠拢的趋势:题材上实现诗词合流,风格上诗词界限不断消弭,文本与音乐不断疏离,在功能上体现出由娱情向述志的转变,创作观念上诗词渐可等量齐观,技法上进一步向诗歌领域借鉴,这就是苏轼"以诗为词"的主要内容。
