The Neo-Riemannian theory is not only suitable for analyzing music with the ambiguity of harmonic functions in later Romanticism but also finds relevance between chords in the 20th century focused on the atonal music analysis. This paper employs the Neo-Riemannian theory to the last piano solo by César Franck based on the basic triadic transformations of P-relation, R-relation, and L-relation, as well as N-relation, H-relation, and S-relation, which are of integrated relations of transformations. At the same time, the symmetry and distance relationships of the triads can also be intuitively seen in the tonnetz model, which reflects Franck’s tonality and personalized creation of using triads. Importantly, this analysis provides a theoretical basis for a comprehensive understanding of Franck.
