Firstly, this second movement is strongly instrumental in character, and it is not incorrect to consider it as a string quartet. Even if not a string quartet, it should in any case be regarded as an instrumental ensemble. What requires attention in this movement are the dynamic markings. Since the notation varies by edition, this explanation is based on the score the author is consulting, but this movement fundamentally progresses with alternating forte and piano dynamics. The problem arises when one takes the written dynamic markings at face value, for instance, suddenly playing with a large sound in both hands when a forte appears; this is certainly to be avoided. Instead of focusing on the location of the dynamic markings, one should consider the musical material.

At the beginning, for measures 1-2, arpeggios in thirds begin in the right hand, overlap with the left hand, and the left hand also proceeds with arpeggios in thirds; this material should be considered as units of three eighth notes. That is, in the example of measures 1-2, the melodic line C C A, starting from the anacrusis (though strictly six eighth notes), should be treated as one unit. In that case, the A should be played slightly softer than the C C. Play it as if fading away, and ensure that the last note of this unit does not receive an accent.

However, here lies the problem: a forte is written in the right hand on the second beat of measure 2, which should be considered new material. However, some performers suddenly play the left hand in this section (measure 2, beat 2) also forte. The left hand on the second beat of measure 2 is the last note of the material that begins on the first beat, and it must be played softly. Furthermore, since it begins a second lower than the same material in measure 1, it must be played even softer. When considering the musical material or phrasing, regardless of whether forte or piano is written, one should think about whether that note is the last note of a phrase, or the beginning note, etc., and approach it based on the phrase or material.
