Étude Op. 10, No. 10 (Chopin)

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.

The climax of the central section starts at bar 43 and at this point it is the left hand that is playing off-beat whilst the right hand maintains a strict four beats per bar.

The tonic appears only very briefly in this final section and is not fully reestablished until bar 69, which is effectively the coda.
