The key of D minor, as employed by Bach, exhibits many facets, but a common characteristic across all works is its highly dramatic nature. This prelude is broadly divided into two sections: a slow, lyrical first half (measures 1-37) and an Allegro (measures 38-195).

The first 37 measures should be played with a sense of spaciousness and ample lyricism, never conveying a feeling of impatience. Pedal usage is essential. Of particular note are the instances of notes with two stems, such as the D in the right hand on the second beat of measure 1, and similarly the C-sharp in the right hand on the third beat. These notes should be consciously brought out slightly more prominently than other notes.

While the Allegro section is long, it does not necessarily build towards a specific peak. A tip for performance is to be mindful of the cadences and divide this Allegro section into three parts. The locations of the cadences are as follows:

• First: measures 85-86
• Second: measures 113-114
• Third: measures 142-143

Aim to differentiate the character of each section. For example, after the first section concludes, try playing the second section with a relatively light and soft tone. Dividing the piece into sections in this manner will make it clearer and more accessible to the listener.
