The form entered the concert hall with [[Franz Liszt]]’s ''Études en 12 exercises'' in about 1827 (These pieces were to finally become the ''Études d’exécution transcendante'' – or “''Transendental studies''” - among the most difficult to play of all piano works.); however it is [[Frédéric Chopin]]’s two sets (Opp. 10 and 25, published in 1833 and 1837) that established the etude as an artform; and are the most frequently performed today. Of the various other sets of studies written for the piano, only those of [[Claude Debussy]] have lasting popularity. | The form entered the concert hall with [[Franz Liszt]]’s ''Études en 12 exercises'' in about 1827 (These pieces were to finally become the ''Études d’exécution transcendante'' – or “''Transendental studies''” - among the most difficult to play of all piano works.); however it is [[Frédéric Chopin]]’s two sets (Opp. 10 and 25, published in 1833 and 1837) that established the etude as an artform; and are the most frequently performed today.
