Franz Liszt (1811-1886) Études d'exécution transcendante S.139, No.11 in D-flat Major "Harmonies du soir" from Wikipedia: The Transcendental Etudes S. 139 began in 1826, as a set of youthful and far less technically demanding exercises called the Étude en douze exercices (Study in twelve exercises) S. 136. Liszt then elaborated on these pieces considerably, and the far more technically difficult exercises called the Douze Grandes Études (Twelve Great Studies) S. 137 were then published in 1837. The Transcendental Etudes S. 139 are revisions of his Douze Grandes Etudes. As the third and final version, this set was published in 1852 and dedicated to Carl Czerny, Liszt's piano teacher, and himself a prolific composer of etudes. 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 piece more suitable for pianists with smaller hands and less technical skill. However, the four! th etude of the final set, Mazeppa, is actually more demanding than its 1837 version, since it very frequently alters and crosses the hand to create a "galloping" effect. When revising the 1837 set of etudes, Liszt added programmatic titles to all but the Etudes Nos. 2 and 10. These titles are in French and German.
