The compositional style of Franz Liszt was significant for its virtuosic feature, the use of thematic transformation technique, and transcriptions, which usually makes people ignore the importance of deep literature relationship in his music. In the Années de Pèlerinage: Deuxième Année written in 1838~1839, it has included compositions inspired from literature and arts. For the Three Sonetto of Petrarca from Années de Pèlerinage: Deuxième Année, Liszt had written five editions, which had never seen in other compositions. This research, based on the tenor edition published in 1846, focuses on the relationship of music and literature in the Three Sonetto of Petrarca piano edition published in 1858. Furthermore, Liszt’s use of the technique of word painting, third relationship of harmonic language, and the unity between introduction and coda to build the construction of the poems is also explored.
