Pianoforte technique might almost be said to be divided into two schools.
The one seems as if it were exactly adapted to suit the peculiar powers of the instrument, and is that which, having been greatly modernized by Chopin, culminated in the genius of Liszt. The passage writing of both these pre-eminent composers for the piano are unsurpassed as pure pianoforte technique both as regards expression, effectiveness and brilliancy.
The other school, on the contrary, could almost be described as having developed on lines antagonistic to the piano’s natural limitations and even to those of the human hand. Some of the finest pianoforte works, however, are to be found in this category, two of its greatest representatives being Schumann and Brahms. (It must be remembered that I am speaking here entirely from the point of view of purely mechanical technique, and not considering the musical side of the question at all.)
This is why many of the pianoforte compositions of Schumann, and especially also of Brahms, are so terribly difficult to master. Brahms never seemed to stop to consider much about the limitations of the instrument he was writing for, but let his imagination and creative faculty develop unhindered, and undeterred, by questions of technical unsuitability. Thus some of his most beautiful passages are written almost in defiance of the natural technique of the piano, so that the pianist, in order to arrive at investing them with their full significance and effect, would often be glad of twenty fingers to play them with instead of the mere ten which he possesses!
In this kind of music, tending as it does more towards orchestral effects than to purely pianistic ones, the player must often resort to fingering that at first seems against all reason, to obtain the mastery over the difficulties. For though in general in all piano playing the principle should be firmly established that the hand must look natural and elegant to the eye upon the keyboard, yet here that rule must be thrown overboard, in order to preserve the necessary expression and plasticity.
