Étude Op. 10, No. 8 (Chopin)

The first section (bars 1–28) features a right-hand figuration that is straightforward with the accent falling always on the first note of each group of four semiquavers throughout the work.

The main difficulty is that they must be played forte and legato at speed, ascending and descending sequentially over the keyboard.

Due to the obligation to sustain the left-hand melody somehow whilst still keeping the right hand's figure clear, this presents a great difficulty.

The central section (bars 29–60) features elaborations on the original figuration.

As with the opening section, the accent always falls on the first note of each group of four semiquavers.
