Gigue

While there are numerous gigues by Bach, I find gigues with such an elevated level of tension as this one to be rare. Numerous diminished seventh chords are present, and the leaping figures unequivocally suggest a departure from a state of typical mental stability.

To state the conclusion upfront, one should not aim for a "beautiful" rendition of this gigue. It is better characterized by terms such as "acerbic," "rough," "forceful," "instrumental," and "agitato."

Consequently, regarding articulation, for instance, in the opening measure, all eighth notes should be played staccato. Furthermore, the dotted quarter notes should not be connected seamlessly to the subsequent eighth notes; rather, it is advisable to cut them short. While the accent tends to fall more strongly on the dotted quarter notes, the eighth notes should also be executed dryly, non-legato, and marcato.

Around measure 49, attempt to play forte, treating this section as the peak of the gigue's intensity. Although it concludes with a Picardy third, ensure that the tension is maintained without abatement until the very end.
