Two Concert Études (Zwei Konzertetüden), S.145, is a set of two piano works composed in Rome around 1862-63 by Franz Liszt and dedicated to Dionys Pruckner, but intended for Sigmund Lebert and Ludwig Stark’s Klavierschule. It consists of two parts: Waldesrauschen (Forest Murmurs) and Gnomenreigen (Dance of the Gnomes).

The second piece is Gnomenreigen (Dance of the Gnomes). It is known for its technical difficulty in its fast and soft passages, where the pianist imitates the sound of gnomes. It first has a theme consisting of grace notes followed by eights. Then it goes to a fast, playful theme in A major. It repeats themes, and also has a theme with repeating bass notes, such as the 60 low Ds in a row. Finally, the A major theme is repeated for a climactic part of the étude, this time in F-sharp major. (Wikipedia)
