Lőrinc Kesztler’s Theory of the Harmony of Classical Music was first published by Károly Rozsnyai’s publishing house in 1928 and later by the Hungarian State Music Publisher in 1953. It has been a standard work in the education of music theory ever since. The volume consists of three chapters that introduce diatonics, chromatics, and figuration. The appendix contains the developed version of the lessons for the relevant chapters.
