Two Concert Études (Zwei Konzertetüden), S. 145, is a set of two piano pieces 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). It has been speculated that the titles probably weren't given by Liszt.
