Bach's C major often evokes an image of innocence and purity. However, this particular fugue, unlike the typical perception of C major, can be described as very optimistic. Throughout almost the entire piece, 16th notes are present, and in the latter half, these 16th notes continue without interruption. They do not cease even when relayed to another voice, continuing until the final cadence.

These continuous 16th notes express anticipation, convey joy, and depict a gradual heightening of emotion. Therefore, choosing a fast tempo, felt in two beats per measure, is reasonable.

The theme is considered to be the first two measures. For instance, within these measures (1-2), the A on the first beat of measure 2 is the peak point of the theme.

Consequently, it is advisable to play the G on the second beat of the same measure slightly softer than the A. Apply similar shaping whenever the theme reappears.

Although this fugue expresses joy, it does not possess the same power as F major or A major; rather, consider it a joy within an elegant context.
