bennom, are there any secrets you've gleaned from learning and playing this piece? maybe letting the sound bang around? playing really relaxed? also, there's so much repetition in certain places - you must have to play as an echo here and there.
There are no secrets. I found the promenades the most difficult, especially the first has a tendency to sound flat, or to heavy, or not heavy enough. I just tried to play it with simple phrasing yet heavy ringing tone. In the gnomus I added octaves in the left hand, it sounds to more scaring. (stole it from horowitz)
In bydlo I think it's important to keep the crescendo constant and without even the slightest accelerando. In Goldberg and schmyle I played the "schmyle" part quite freely and extremely expressive. In il vecchio castello it's all about finding perfect voice balancing.
The chicken ballet trio I played with rythmical trills in the r.h.
All over , I found it really effective to use extreme pedal, sometimes none, sometimes "too much" to make the sound body expand like ringing church bells. In the end, the bass strings were actually colliding with eachother from over-vibrating, which made a buzzzing noice, haha.
In "the Gate of Kiev" I tried to use different length for the grace notes, some quick and some heavy, to create a mayhem of bell ringing.
...I'm sure there is more I could say, but it's not easy to explain in writing.
