We are going to be using this thread to gather suggestions and questions!
- What questions do you have on this topic?
- Any particular area you would like me to focus on?

I wonder if you can speak to the role of extemporazation in Bach (and other Baroque composers), as to both ornamentation and rhythm. For example, when is unwritten ornamentation too much or improper; and am I allowed to decide to prolong the dot after a note while shortening the corresponding following note?

There is a small ornament I would like to play in the Bb Major Prelude from book 2 of the WTC . It's a simple little 3 note shake which I believe would be described as an inverted mordant on the first G in triplet appearing at Beat 3 of Measure 2 (circled in RED in the attached PDF).
I can execute it fairly easily when simply playing it by itself in 1 hand, but in the context of playing the piece with both hands, my RH hand seems to lock up on this ornament. I have to push through the lock-up and it results in a *hitch* in performing the ornament.
For the life of me, I can’t figure out what I am doing differently with my hand when I play the preceding notes. I suspect that the culprit may be the little Turn I do on the Eb in the soprano, beat 4 of Measure 1 (circled in green), but I cannot ascertain what it would be doing to my hand to cause it to lock up when I arrive at this problematical ornament.
I've also uploaded a short video illustrating my hand position when playing the ornament (a) alone, and (b) in context of the other notes.
Any feedback would be most welcome!
P.S. These sessions are really great and I always learn so much from Dominic's advice to myself and the other pianists.

I posted my questions in another thread but will copy it here.
I have a general question about tempo. In the past, I tend to rush through a piece and try to play at a fast tempo before I am ready. I started practicing at a very slow tempo so I will get all the rhythm and note correctly. I watch your other livestream where you talk about practicing close to your goal tempo with very short section, like 1-2 bars at a time. When I try to do the fast tempo, that is when I realize some of the fingering would not work. Now I have to go back and re-learn the new fingering. And it sounds worse than before and I feel like I am not making much progress. I cannot even get through a few bars at a time.
Question:
1. What practice tempo do you recommend in the early stage of learning a piece? Do you go back and forth with slow, moderate and fast every time you practice?
2. This is my first WTC prelude and fugue (WTC book 2 G major). What tempo do you recommend? I heard some insanely fast tempo and there is no way to get even close.
