This document is organized in three chapters preceded by a general introduction. The multifarious figure of Zoltán Kódaly is evoked by one of his most distinguished students, piano virtuoso György Sándor, in the manner of a conversation with the author of this thesis. The format of the dissertation is, thus, that of an oral history in which Kodály the man, the teacher, and the composer is brought alive through the reminiscences of his pupil. The first chapter examines the human profile of Kodály, his personality, idiosyncracies, and above all, his patriotism and unwavering commitment to the musical enlightenment of the Hungarian people. Special attention is given to his solidarity and loyalty to a country ravaged by totalitarian regimes of Nazi and communist affiliation. Kodály's pedagogical philosophy is considered in the second chapter. Maestro Sándor takes us back to his years at the Liszt Academy in Budapest, where he studied composition under the guidance of Kodály, and piano with Bartók. The third chapter explores Kodály the composer, and demonstrates how the ethnomusicologist, the pedagogue, the creator, and the man constitute in his case a perfectly harmonic and indivisible unity. The appendix includes pictures, documents, and a concise biography of maestro Sándor, complemented by his discography, some representative recital programs, and a list of his publications.
