For now I would say... well done Nancy because there is a beautiful spirit in what you play, especially one feels the respect you have for Bach's music, but perhaps that is exactly what is blocking you a little. Mine are not judgments, let that be clear, but... just sensations. I would merge more with the piece. The piece proposed by Luca is beautiful, but watch out!! The organ is not the piano and we are talking about two diametrically opposed languages. Dancing and sprightly, okay, but on the piano, I would rethink it differently.
I feel it, for example, as separate steps in your execution, whereas they should be ramps of stairs with their landings. In Luca's proposal, I would listen more to the phrases made by the choir and worked on large arcs of phrasing that start, realize, and conclude, but the organ brings them out because it sounds that way due to its long sounds. The bass you play, for example (very well calibrated), would require the greatest possible legato, and also the dynamics—rather than arriving suddenly, they should be more calibrated; I mean creating more dynamics by lowering the weight more on the steps where you already play piano... (in the sense of playing even more softly while crescendoing in a calibrated way). It is also felt that the piano is not helping you (in fact, certain sounds almost pushed to try to make some notes sing seem to be due to the fact that the instrument does not respond... even out of tune? Ha ha). If I find it online, I'll send you something to make you understand what I mean, even if the piece has a different spirit from this.
You have taken on quite a headache... the conflict in this piece between its expressive, cantabile character and its jubilation is not easy at all. In my opinion, you will have to make an expressive choice, but clearly giving precedence to one of the two factors; at least on the piano, in order to give the listener a direction and a secure aesthetic sense upon which to base their listening; in short, so as not to disorient them.
Many times, to clarify for myself how to play, for example, a Mozart adagio, I would listen to another adagio; I assure you it can help.
In conclusion, I agree with Gianni: also for me, beautiful spirit and 80% of the work is done.
Thank you for playing for us.
I'm running to look for the piece.
