Liszt: Complete Etudes for Solo Piano, Series 1Including the Transcendental Etudes This first volume includes many of Liszt's most inspired piano works. The Etude en 12 Exercises and the 12 Grandes Etudes can both be regarded as early versions of the Etudes d' Execution Transcendante. The separate "Mazeppa" is yet another working of one of the etudes from these sets. The individual etudes range from the delicate refinement of "Feux Follets" to the startling bravura of "Wilde Jagd."
