This Gigue possesses a psychologically severe aspect; for instance, when compared to the Prelude in D minor from Book I of the Well-Tempered Clavier, which is also in a quadruple meter, there are no moments of tranquility. It features chromaticism, which was considered a "distorted world" at the time.

Furthermore, the trills constantly heighten the tension, expressing a restless psychological state. It is considered an extremely dark world even among Bach's works.

This Gigue is also technically very challenging, requiring difficult techniques such as playing long trills simultaneously with regular notes, similar to those employed by Romantic composer Franz Liszt. For example, in measure 8, it is naturally impossible to play the trill and the triplets simultaneously; therefore, this trill should be taken by the left hand, which will also play the eighth notes in the bass clef.

Of course, care must be taken to ensure the trills do not sound heavy, but the eighth notes played with the trills should have the same length as, for example, the eighth notes in the right hand of measure 3 that do not involve a trill. We are well aware of the difficulty. However, changing the articulation simply because a trill is present is by no means good for the independence of the voices. Please strive to maintain the articulation of the eighth notes whether a trill is present or not.
