Transcendental Étude No. 11 in D-flat, "Harmonies du Soir" is the eleventh étude of the set of twelve Transcendental Études by Franz Liszt. This étude is a study in harmonies, broken chords played in quick succession, full octave jumps, chromatic harmonies, chord variations, interlocking hands, bravura, massive chords, especially proper pedaling, and performance as a whole.

This piece is considered one of the most artistic of the études, along with No. 12 "Chasse-neige".
