The primary point of attention for this prelude is to differentiate the tone quality of the accompaniment and the melody line. The number of notes in the accompaniment is several times that of the melody line, and if played normally, the accompaniment will inevitably be louder, obscuring the melody line. To prevent this, one should play the accompaniment pp, but this is precisely where the difficulty of this prelude lies; it is so challenging that it could almost be considered an etude.

Therefore, this time, I will explain how to play the left-hand (primarily) accompaniment pp. When attempting to play pp, notes tend to drop out, unevenness occurs, or the clarity of individual notes suffers. The following practice methods can resolve these issues. We will take the pairs AF and FD in the opening left hand of measure 1 as an example.

Assume the fingering for AF is 4-1, and for FD is 5-2. The following discussion is based on these fingerings.

Exercises

• Press F with finger 5, and while keeping it depressed, practice the tremolo of AF and D.
• Press F with finger 1, and while keeping it depressed, practice the tremolo of DF and A.
• Press the F octave with fingers 1 and 5, and while keeping them depressed, practice the tremolo of the inner voices D and A.
• Press A and D with fingers 4 and 2, and while keeping them depressed, practice the tremolo of the outer voice F octave.
• Press F and A with fingers 5 and 4, and while keeping them depressed, practice the tremolo of F and D.
• Press F and D with fingers 1 and 2, and while keeping them depressed, practice the tremolo of A and F.

As you perform these exercises, you should feel a tension in your forearm muscles. If this occurs, it indicates that the exercises are having an effect. If you play normally after practicing the above exercises, it should feel significantly easier.

For the tremolo in the third beat of measure 7, most people will likely find it difficult to reach, so the upper voice should be taken by the right hand.

While the interpretation of this piece may vary among individuals, the author believes it is certainly an expression of sadness and loneliness. It can also be interpreted as a depiction of many memories alternately resurfacing in one's mind.
