of the upper part by pressing the keys to the bottom with firm and straight fingers. To ensure even action of the fingers playing the figure in semiquavers he recommends to start practicing in a non legato where the fingers do not lose contact with the key. For the final legato the weight of the hand should bear slightly on each semiquaver to produce a kind of portamento with a timbre that will not merge into the upper melodic line. Cortot also introduces an exercise for flexibility of the foot to produce an "uninterrupted quivering" pedal, but advises to practice the finger legato first without pedal. There are no original pedal marks by Chopin. Arrangements A version for the left hand alone can be found in Leopold Godowsky's 53 Studies on Chopin's Études. Canadian pianist Marc-André Hamelin (born 1961) describes this "most beautiful achievement" thus: "A continuous, rapid line of demisemiquavers snakes its way around and through Chopin's melancholic chorale, enhancing it without being in the least bit obtrusive."
