The purpose of this study is to understand Liszt's music using the intertextuality theory of Kristeva. The intertextuality theory is based on post-structuralism that there might not be a purely new work on any composer's. It is a mere fabricated thing which is reflected by unconsciousness of composer's experiences. Liszt is one of the most influenced composers by literature, philosophy, and art. Especially he composed not a few piano works on poets. 《Mazeppa》is the one he composed using poem of Victor Hugo. It comprised intertextual elements of carnaval languages and 'menippea' which Kisteva suggested for analyzing literature. The other conception of 'chora sémiotique' was also involved in his work. As the result of this study, the conversion of diachrony into synchrony in turn and the distinction between carnaval languages and menipea were found to be able to apply to music not only literature. This result would suggest a new significant method, as an alternative of traditional method, in music understandings.
