It is Andante in 2/4 time, but how slow should it be? And is this second movement primarily instrumental? The author believes this second movement has strong aria-like elements. For example, the 32nd-note scales appearing in measures 23-26 should, in the author's opinion, be played as if an opera singer were joyfully singing, without sounding rushed or pressured.

In other words, if interpreted instrumentally, it might become too lively or virtuosic, which is certainly one valid approach; however, in any case, please keep in mind that it is Andante, and avoid making it sound excessively rushed.

Unpleasant sounds on the piano tend to occur when the same note is repeated consecutively. The main theme in the right hand, "DDDD" in the first measure, appears throughout the piece. Normally, this would be the melody line, and the accompanying scale figure below it would be kept subdued to maintain balance, but for this piece, some adjustment is needed.

Minimize the volume of the right-hand "DDDD" and give it direction. For example, play the "DDDD" from measure 1 so that it leads to the D on the first beat of measure 2. Ensure that the four D's are never played at the same volume. Furthermore, by keeping the "DDDD" volume subdued and slightly emphasizing the accompaniment's HAG, you can prevent the "DDDD" from sounding harsh. Experiment with various balances with the left hand to ensure the "DDDD" does not become unpleasant.
