The "Transcendental Études" are revisions of his "Douze Grandes Études". This third and final version was published in 1852 and dedicated to Carl Czerny, Liszt's piano teacher, and himself a prolific composer of études. The set included simplifications, for the most part: in addition to many other reductions, Liszt removed all stretches of greater than a tenth, making the pieces more suitable for pianists with smaller hands. However, some actually regard the fourth étude of the final set, "Mazeppa", more demanding than its 1837 version, since it very frequently alters and crosses the hand to create a "galloping" effect.
