What you should definitely consider in this prelude is 'directionality.' Give a sense of direction towards the target note, and once the goal is reached, allow the sound to gradually recede.

The goal in this prelude is the dotted eighth note. The theme begins from bar 1.

Starting from bar 1, aim towards the dotted eighth note A in the right hand on beat 2 of bar 2. Begin p, and since this A on beat 2 of bar 2 is the first target note, make a crescendo towards it. Once you reach A, make a diminuendo.

Next, in bar 3, the left hand follows the exact same phrase in E minor, so reach the dotted eighth note E on beat 2 of bar 4. Continue similarly thereafter. Bar 5 is a sequence of bar 4, and after this, the theme begins in the right hand from bar 6. Bar 8 is a sequence of bar 7.

From bars 8 to 11, sixteenth notes appear, and the tension rises sharply. In bar 12, the final theme appears in the left hand. Aim towards A on beat 2 of bar 13.

Bars 14 to 16 form a cadenza. You may incorporate improvisational elements.
