As regards technics, two things are to be studied: the staccato of the chords and the execution of the cantilena. The chords must be formed more by pressure than by striking. The fingers must support themselves very lightly upon the chord keys and then rise again with the back of the hand in the most elastic manner. The upward movement of the hand must be very slight. Everything must be done with the greatest precision, and not merely in a superficial manner. Where the cantilena appears, every melodic tone must stand apart from the tones of the accompaniment as if in "relief." Hence the fingers for the melodic tones must press down the keys allotted to them with special force, in doing which the back of the hand may be permitted to turn lightly to the right (sideward stroke), especially when there is a rest in the accompaniment. Compare with this etude the introduction to the Capriccio in B minor, with orchestra, by Felix Mendelssohn, first page. Aside from a few rallentando places, the etude is to be played strictly in time.
I prefer the Klindworth editing of this rather sombre, nervous composition, which may be merely an etude, but it also indicates a slightly pathologic condition. With its breath-catching syncopations and narrow emotional range, the A minor study has nevertheless moments of power and interest. Riemann's phrasing, while careful, is not more enlightening than Klindworth's. Von Bulow says: "The bass must be strongly marked throughout—even when piano—and brought out in imitation of the upper part." Singularly enough, his is the only edition in which the left hand arpeggios at the close, though in the final bar "both hands may do so." This is editorial quibbling. Stephen Heller remarked that this study reminded him of the first bar of the Kyrie—rather the Requiem Aeternam of Mozart's Requiem.
It is safe to say that the fifth study in E minor is less often heard in the concert room than any one of its companions. I cannot recall having heard it since Annette Essipowa gave that famous recital during which she played the entire twenty-seven studies. Yet it is a sonorous piano piece, rich in embroideries and general decorative effect in the middle section. Perhaps the rather perverse, capricious and not altogether amiable character of the beginning has caused pianists to be wary of introducing it at a recital. It is hugely effective and also difficult, especially if played with the same fingering throughout, as Von Bulow suggests. Niecks quotes Stephen Heller's partiality for this very study. In the "Gazette Musicale," February 24, 1839, Heller wrote of Chopin's op. 25:
What more do we require to pass one or several evenings in as perfect a happiness as possible? As for me, I seek in this collection of poesy—this is the only name appropriate to the works of Chopin—some favorite pieces which I might fix in my memory, rather than others. Who could retain everything? For this reason I have in my notebook quite particularly marked the numbers four, five and seven of the present poems. Of these twelve much loved studies—every one of which has a charm of its own—the three numbers are those I prefer to all the rest.
The middle part of this E minor study recalls Thalberg. Von Bulow cautions the student against "the accenting of the first note with the thumb—right hand—as it does not form part of the melody, but only comes in as an unimportant passing note." This refers to the melody in E. He also writes that the addition of the third in the left hand, Klindworth edition, needs no special justification. I discovered one marked difference in the Klindworth edition. The leap in the left hand—first variant of the theme, tenth bar from beginning—is preceded by an appoggiatura, E natural. The jump is to F sharp, instead of G, as in the Mikuli, Kullak and Riemann editions. Von Bulow uses the F sharp, but without the ninth below. Riemann phrases the piece so as to get the top melody, B, E and G, and his stems are below instead of above, as in Mikuli and Von Bulow. Kullak dots the eighth note. Riemann uses a sixteenth, thus:

Kullak writes that the figure 184 is not found on the older metronomes. This is not too fast for the capriccio, with its pretty and ingenious rhythmical transformations. As regards the execution of the 130th bar, Von Bulow says: "The acciaccature—prefixes—are to be struck simultaneously with the other parts, as also the shake in bar 134 and following bars; this must begin with the upper auxiliary note." These details are important. Kullak concludes his notes thus:
Despite all the little transformations of the motive member which forms the kernel, its recognizability remains essentially unimpaired. Meanwhile out of these little metamorphoses there is developed a rich rhythmic life, which the performer must bring out with great precision. If in addition, he possesses a fine feeling for what is graceful, coquettish, or agreeably capricious, he will understand how to heighten still further the charm of the chief part, which, as far as its character is concerned, reminds one of Etude, op. 25, No. 3.
The secondary part, in major, begins. Its kernel is formed of a beautiful broad melody, which, if soulfully conceived and delivered, will sing its way deep into the heart of the listener. For the accompaniment in the right hand we find chord arpeggiations in triplets, afterward in sixteenths, calmly ascending and descending, and surrounding the melody as with a veil. They are to be played almost without accentuation.
It was Louis Ehlert who wrote of the celebrated study in G sharp minor op. 25, No. 6: "Chopin not only versifies an exercise in thirds; he transforms it into such a work of art that in studying it one could sooner fancy himself on Parnassus than at a lesson. He deprives every passage of all mechanical appearance by promoting it to become the embodiment of a beautiful thought, which in turn finds graceful expression in its motion."
