This is an optimistic and joyful Gigue. Given the placement of the left-hand chords, it is logical to proceed by feeling the beat. What is interesting is that the first half does not conclude after 8 measures (4 measures x 2), but rather consists of an irregular 6 measures.

As one possible interpretation, the first and third beats of measure 1 ascend stepwise, F to G, reaching A in measure 2 and further ascending to C in measure 4. Since this C is the highest note in the first half, it can be considered the peak point.

From there, the soprano H on the third beat of measure 5 descends slightly, so a diminuendo can be applied from measure 4 to this point. As it continues to descend towards C in measure 6, a continued diminuendo would be acceptable; however, another idea is to apply a crescendo from the third beat of measure 5 towards measure 6, leading to the chord on the third beat of measure 6, and concluding the first half with a forte.

Similarly, the second half also consists of 6 measures, so one could aim for the chord on the third beat of measure 12 and apply a crescendo towards it.

Regarding the irregular measure count of 6 measures, applying dynamics in an unconventional manner can create a surprising effect.
