Rewriting Scores

[qpalqpal]

As I scoured through this forum to find out the best way to practice, I came upon the Bernhard method and have been using it to some extent. I am sure his method works because it makes a lot of sense and is very efficient. One thing I noticed was that he mentioned starting a piece by reducing it to its skeleton; remove the superfluous notes and make it a novice piece and write it out. This seems very practical, especially for difficult piece such as for example, Chopins Prelude 8 or the like where there is a melody and many notes which are secondary, adding to the melody.

I am practicing rather 'simple' pieces, such as Clementi Sonatinas and namely Skrjabin's Prelude 4. For Skrjabin, would it still be practical to break the piece down to its melody. It seems pretty simple to me, but I have a feeling that reducing it to its skeleton is a good idea. Anyone?

Also, do you like to write out scores by hand or digitally. Thoughts
