The Trois Études de concert (Three Concert Etudes) for piano solo were written at the beginning of Liszt's work as a conductor in Weimar. The original manuscript, which was lost for some time in the Bibliothèque musicale François-Lang, revealed many details that were previously overlooked. It is that original manuscript which serves as the main source for the Urtext edition presented here. The contents are No. 1 Il lamento A flat major, No. 2 La leggierezza F minor, and No. 3 Un sospiro D flat major.
