Which piano technique did Chopin use?, which one could suit me?

[faa2010]

Today I heard that there are different music "school" with different techniques: french, german, russian.

My teacher told me that I should choose one of them, she is from the french school (the movement is with the fingers, not with the arms), and depending in what I want, she will continue on being my teacher.

I feel confused and scared, but I was thinking that I want the school that can suit my personality (I am shy, tender, introverted, hardworking, and I like the softness, but I can get sometimes scared and insecure).

Also,  because I love Chopin, Ravel, Debussy, I would like to Know which school did they choose (although I think Ravel and Debussy were part of the french school)

Even though Chopin had "teachers" his piano technique was largely self-taught, he didn't belong to any piano school. Although you can argue that he had some influence for French pedagogy (a good portion of his students were based on paris), I would still say they're loosely associated. I would look at works/writings by his pupils, the music that shaped his tastes and approach to music. Look at Hummels, Field, Kalkbrenner and so on; the style of music Chopin, contemporary polish musicians, and a lot of his classmates practiced in.

The idea of piano schools is a bit simplified and less significant in today's more globalized music world.
You should develope a basic technique that suits your hands. How you play is also reflecting your personality. Then depending on the music played you vary the techniques accordingly and either go for period and style appropriate choices or be bold and do something new and different (better be good then).

I think you should listen and observe pianists play the same music to help you make choices.

Also composing style and playing style were not always separate things. The pianist composers of the past wrote for themselves and developed their technique and composition style simultaneously. Only later did all these pedagogical schools emerge that were more general to playing.

Thanks, I have decide to play as I feel and want. I want to play in a tender and sweet way, as well as finding a way to play without been stiff and rigid, I want to play with my hands and wrists relaxed.

Don't conflate physical technique with the sound you want to produce.  They aren't necessarily the same thing.

Your technical approach should allow you to produce any sound you want in a healthy manner. 

Also, rather than trying to pre-suppose a certain sound, actually "get into" the notes before deciding how you decide to express yourself within those boundaries.
