Étude No. 11 is a study in arpeggios and chords, involving difficult left-hand stretches and an unusual emphasis on the use of the right-hand thumb. Like the preceding and following studies (and unlike the earlier ones), it is in ternary (ABA) form, with bell-like effects marking the middle section.[2]
