I think that both Ravel and Chabrier wrote in a very refined manner, which is why Ravel captures the Chabrier idiom so very effectively.
I believe that, though I´m not a true specialist concerning french music. I just have played some preludes and four hands pieces by Debussy and "Jeux d´eaux" by Ravel f.ex. and some other pieces by Debussy/Ravel, but I never have played Chabrier until know. So I don´t know too much about his style.
So, what would you say are the features of his typical style?
This is an important characteristic of much French piano music I think, so is likewise found in the music of Debussy and Faure too.
Yes, I also think, that most french composers, f.ex. all of impressionism and the "groupe des six", are very refined and subtle. French music has something subtle and intellectual, it´s not so emotional in a romantic sense like many german music is.
F.ex. Debussys preludes are very subtle and inventive and the fact, that he wrote the title below the pieces shows a certain modesty, a manner, not to impose the own ideas on his listeners.
