Étude Op. 10, No. 11, in E-flat major, is a technical study composed by Frédéric Chopin. It is sometimes given the tiles Arpeggio-Study, and Guitar-Study. The chief difficulty addressed in this piece is the performance of extended arpeggiated chords. Throughout, the hands are required to stretch intervals as large as compound fifths. The melody, though usually the highest note of each chord, is often found in inner parts with higher parts simply being part of the accompaniment. This is especially the case in the final bars. The piece is also notable for its chromatic harmonies, daring at the time, and enharmonic shifts.
