There are two points to note in this movement: the issues of pedaling and timing.

Pedaling

First, regarding the pedaling issue. The left hand begins with octaves in the exposition and largely continues with octaves until measure 24. When moving from one octave to the next, a break can occur, leading some performers to use the pedal. The articulation involves sustaining a quarter note, connecting it to an eighth note, and then playing the eighth note staccato. While this approach is acceptable, there are measures where this pedaling can cause muddiness, so caution is advised.

In measures like m. 3, which contain scales, or m. 10, which include minor or major seconds, pedaling can lead to muddiness. Therefore, when moving from one octave to the next, it is recommended to use finger pedaling to avoid this muddiness.

Timing

Next, timing. From measure 25 onwards, consider the right and left hands as different instruments. However, if the right hand's ornamentation is too slow, the left hand's second beat might sound like a continuation of the first beat (due to their proximity). Therefore, play the right hand's ornamentation as quickly as possible, making the left hand sound like a distinct instrument.
