Working on this piece right now and want to learn the extra ones. I have heard them played in their entirety but don't remeber where the extra ones were put in. All in a group together? Dispersed amongst the standard ones?I know they have been put in different places, but where?I have the Henle edition, but it's not so clear what they mean (Preface) Also maybe some thoughts on the piece. good? bad? Like? dislike?I personally love the piece and have found it doing wonders for my technique (I guess they are etudes!!). Some of them good for chords like the presto possible. I'm at work so I don't remeber the numbers. Also does anybody know why it goes from etude to variation to etude... It just seems to be sort of randomCheersTom
