Étude Op. 10, No. 10, in A♭ major, is a technical study composed by Frédéric Chopin. This étude places huge demands on the performer in varying a single pattern by changes of accent and touch. Chopin's primary concern in this work is for the widest possible variety of touch that can be given to a single figuration, with the continuous changes of accent highlighting not only different parts of the figuration but also emphasizing the polyphonic nature of the pattern.
