Well with writing a comment on this I may expose myself a bit, but alas, let's take the risk. I don't like to play Bach currently. Why? because there are so many different do's and don't s and so many different opinions of what the "true" Bach interpretation should be like. And there is the whole ancient music- school that makes it hard for us pianists to stand our ground. I know, a lot of you will answer. don't bother, play your own Bach. But perhaps that exactly is what xhunterjx tries. And he soon gets controversy comments. Some would say one should accentuate every strong beat, some want it flowing and phrasing, some others would like double dotted long notes in the fugue, others won't. What remains? at the moment i really think the best would be to learn what the school of ancient music has to say as far as it is scientifically comprehensible. That means study the original sources like C.PH. E. Bach, Froberger, Leopold Mozart and others. Take lessons with a harpsichord player. And so on.
I agree largely with what you say. However, (there is always a but) i would like to add a couple of thing.
I know these are rule, but you can't just say do whatever you want, you will be fine. I we need to try to stick some what to the original sound -- focus in the sound -- more like a plucked instrument and with very little use of pedal. This is basic and i think xhunter does this very well. He has going a good bach touch, certainly. I did not say this before perhaps i should have.
Apart from this i think it's a matter of interpretation. But the music must shine through. Music is not just a set of notes, but there is a message within the music, we need to find the message and express this clearly to the listener. This is why i gave suggestions about phrasing, in the hope that i will help bring out message/musicality of the piece.
If you think that a ridgid sound like a march is appropriate for the prelude, then i say fine, do it more! see if it works for you. If it does, I think you will find that you should be able to convience me of the sound as well. I quite like hearing odd interpretations (that are good i.e. convincing).
With regards to taking lessons from a harpsichord player, I think most of us don't have that luxury. If you do, then go for it! I'm quite happy with modern interpretations as well. I do subscribe somewhat to the school, "if bach had the access to modern instruments, what would he have done?" Of course, there is a huge amount of speculation involved, but that's part of the fun of music.
Lastly, I don't think you should be put off playing bach. Play what you feel sounds right to you. Interpret your music with integrety, and assess what your play with honesty. you will do fine. (why am i telling you this? you are suppose to be the teacher here! and a much, much more experienced pianist!)
