Great job!

This fugue has no real countersubject, as the theme is constructed with a view to strettos and combinations with itself in augmentation and in inversion. The first section runs its course in simple fashion; it consists of two developments in the principal key, the first of which gives the three voice entries, alto (Dux), soprano (Comes), followed by an episode of two measures returning to the principal key, and tenor (Dux) in a period of eight measures; after an episode of four measures begins a second period, closing in the parallel key; it consists first of all of two theme entries:
Comes in the bass (ending with G-major instead of Gminor), and Dux in the soprano, whereupon two repetitions of the fourth measure, with gradual sinking of all the three voices, transplant the close from C-minor to Ab- major and to F- minor. The after -section now begins with the Comes in the alto (yet avoiding the modulation to the minor upper -dominant, and concluding in the principal key); the repeated 6 th measure changes once more the whole-close into a half-close, so that the bass is again able to take the theme (Comes), and indeed, from the harmony of the tonic, closing in the under-dominant. As the under-dominant occurs at the 8 th measure, the latter assumes the meaning of 6 th, i. e. two further measures become necessary, which by sequential formation (one degree higher, but without the theme) transplant the close to G-minor (minor upper-dominant); but as a formation by sequence can never form a satisfactory close, Bach adds a confirmation of one measure with a cadence in G-minor.
The last bass entry, as well as the sequential formation, display in a most striking manner the Neapolitan sixth (minor [Phrygian] second of the minor scale).
Turn on the audio and let me know what you think!
