There are two main points to consider when performing this fugue.

1. Tempo

The first point concerns tempo, which should be determined after understanding the character of this fugue. If we were to describe it in terms of emotions, it is clearly a world of joy, an exhilarating fugue that makes one unable to sit still. Furthermore, the cadenza beginning from measure 61 enhances this sense of delight. Considering this, the tempo of this fugue must always be set "faster than the prelude."

While the prelude also conveys a sense of joy, this fugue expresses "even greater joy," which can be achieved by further increasing the tempo. It is crucial not to play it tamely.

2. Voice Independence

The second point is the consideration for voice independence. This fugue is also very challenging in terms of achieving voice independence, and this should be your goal. For example, in the right hand from measure 16, where the soprano and alto are played simultaneously, the alto notes tend to blend with the soprano, making it difficult to distinguish them. Therefore, various approaches can be devised, such as playing the soprano forte while the alto is played pianissimo (pp), and making the eighth notes staccato. Please implement such voice independence throughout.
