Études (Ligeti)

The Hungarian composer György Ligeti composed a cycle of 18 études for solo piano between 1985 and 2001. They are considered one of the major creative achievements of his last decades, and one of the most significant sets of piano studies of the 20th century, combining virtuoso technical problems with expressive content, following in the line of the études of Frédéric Chopin, Franz Liszt, Claude Debussy, and Alexander Scriabin but addressing new technical ideas as a compendium of the concepts Ligeti had worked out in his other works since the 1950s. Pianist Jeremy Denk wrote that they "are a crowning achievement of his career and of the piano literature; though still new, they are already classics."

There are 18 études arranged in three books or Livres: six Études in Book 1 (1985), eight in Book 2 (1988–1994), four in Book 3 (1995–2001). Ligeti's original intention had been to compose only twelve Études, in two books of six each, on the model of the Debussy Études, but the scope of the work grew because he enjoyed writing the pieces so much. Though the four Études of Book 3 form a satisfying conclusion to the cycle, Book 3 is in fact unfinished, in that Ligeti certainly intended to add more, but was unable to do so in his last years, when his productivity was much reduced owing to illness. The Études of Book 3 are generally calmer, simpler and more refined in technique than those of Books 1 and 2.

The titles of the various études are a mixture of technical terms and poetic descriptions. Ligeti made lists of possible titles and the titles of the individual numbers were often changed between inception and publication. Often Ligeti did not assign any title until after the work was completed.

Étude No. 14A: Coloana fara sfârşit (Column without End) was the first version of Etude 14 but was judged too difficult for a human player, so Ligeti recomposed it, changing the harmonic structure as he reduced the number of pitches in each hand. Subsequently the original form was arranged as a separate étude for player-piano by Jürgen Hocker, but some pianists have in fact played it. The single piano piece L'arrache-coeur (1994) was apparently originally intended to be Étude No. 11 but did not become part of the cycle.
