Lyapunov is largely remembered for his "Douze études d'exécution transcendente". This set completed the cycle of the 24 major and minor keys that Franz Liszt had started with his own "Transcendental Études" but had left unfinished. Not only was Lyapunov's set of études as a whole dedicated to the memory of Franz Liszt, but the final étude was specifically titled "Élégie en mémoire de François Liszt". In the UK the pianist Edward Mitchell was an early advocate, first performing and broadcasting the "Douze études" in 1927. Louis Kentner made the premiere recording in 1949.
