I know that some of you will ask why I use a pick. - It`s for getting better staccato sound, like in "original" version (check out for example performances of Sviatoslav Richter or Glenn Gould). Notes in this charming piece needs to be like this expressive - strong, raw and sharp. And fingering can`t give it.
