By way of mixing heterogeneous voices in modern poetry, Kim So-wol(김소월) created the poetic discourse of negating the colonial modernity. It was one of the alternative voices which could recall the residual culture which had been repressed by the dominant culture, and reveal the barbarousness that all cultural records and historical process had concealed, and disrupt the identity of colonial discourse internally. So I think Kim So-wol`s poetic discourse can arouse a lot of reader`s sympathy today. In this paper, I attempted to evaluate Kim Sowol`s three early works, “The Street of Seoul”(서울의 거리), “Majusuk”(마주석), “Kunginchang”(궁인창), which were discovered recently by the magazin “Hyundaemunhak” (현대문학). “The Street of Seoul”(서울의 거리) shows the inward landscape of the marginal man who was able to select neither the traditional world nor the cononial-modern world. And in this work, it proves that Kim So-wol`s revolving to Traditionalism came from the extreme sense of alienation and despair of the colonial intellectuals. Especially “the Poetic I” in this work shows us the split of vision and identity because of inability to adapt himself to the colonial-modern society. I think that these aspects of the work could be found in Jung Jiyong`s poetry written in late 1920`s again. But Unfortunately Kim So-wol did not persue this critical way of expressing the colonial world any more. It was the expressing the Voice flowing out from the horizon of tradition that Kim So-wol concerned. In other word, He selected the Traditionalism instead of the sensitive description of Modernity and the critical approach to Modernity. In Kim So-wol`s Traditionalism poems, the audible is more important than the visible, and the transcendental world is more important than the phenomenal world. This revolving to Traditionalism can be found more clearly in the works, “Majusuk”(마주석), “Kunginchang”(궁인창). In the work Majusuk”(마주석), Kim So-wol shows us the nostalgia toward the original world that can be captured only in the form of shadow. In this work, the poetic “I” rediscovered the ancestor`s soul. It shows that Kim So-wol wanted to express the voice of the others who could not be erased by the colonial discourse. And in the work “Kunginchang”(궁인창), Kim So-wol prepared the way of mixing the voice of tradition flowing out from the horizon of modern times into lyrical poetry. So we can say that the voice of tradition in Kim So-wol`s poetry, especially in “Chohon”(초혼) was formed in this way
