"At our first lesson Liszt could not tear himself away from the piece. He repeated single parts again and again, sought increased effects, gave the second part of the minor in octaves and was inexhaustible in praise of Weber. With Weber's sonata in A flat Liszt was perfectly delighted. I had studied it in much love with Wehrstaedt at Geneva, and gave it throughout in the spirit of the thing. This Liszt testified by the way in which he listened, by lively gestures and movements, by exclamations about the beauty of the composition, so that we worked at it with both our heads! This great romantic poem for the piano begins, as is well known, with a tremolo of the bass on A flat. Never had a sonata opened in such a manner! It is as sunshine over the enchanted grove in which the action takes place. The restlessness of my master became so great over the first part of this allegro that even before its close he pushed me aside with the words, 'Wait! wait! What is that? I must go at that myself!' Such an experience one had never met with. Imagine a genius like Liszt, twenty years old, for the first time in the presence of such a master composition of Weber, before the apparition of this knight in golden armour!
"He tried his first part over and over again with the most various intentions. At the passage in the dominant (E flat) at the close of the first part (a passage, properly speaking, the sonata has not; one might call it a charming clarinet phrase interwoven with the idea) Liszt said, 'It is marked legato. Now, would not one do it better pp. and staccato? Yet there is a leggieramente as well." He experimented in all directions. In this way it was given me to observe how one genius looks upon another and appreciates him for himself.
"'Now what is the second part of the first allegro like?' asked Liszt, and looked at it. It seemed to me simply impossible that any one could read at sight this thematic development, with octaves piled one on another for whole pages.
"'This is very difficult,' said Liszt, 'yet harder still is the coda,' and the combining of the whole in this close, here at this centrifugal figure (thirteenth bar before the end). The passage (in the second part, naturally in the original key of A flat), moreover, we must not play staccato; that would be somewhat affected; but we must also not play it legato; it is too thin for that. We'll do it spiccato; let us swim between the two waters.'
"If I had wondered at the fire and life, the pervading passion in the delivery of the first part by Liszt, I was absolutely astonished in the second part at his triumphant repose and certainty, and the self-control with which he reserved all his force for the last attack. 'So young, and so wise!' I said to myself, and was bewildered, absorbed, discouraged.
"In the andante of the sonata I learned in the first four bars more from Liszt than in years from my former good teachers. 'You must give out this opening just as Baillot plays a quartet; the accompanying parts consist of the detached semiquavers, but Baillot's parts are very good, and yours must not be worse. You have a good hand, and can learn it. Try it, it is not easy; one might move stones with it. I can just imagine how the hussars of the piano tear it to pieces! I shall never forget that it is through you I have learned to know the sonata. Now you shall learn something from me; I will tell you all I know about our instrument.'
"The demi-semiquaver figure in the bass (at the thirty-fifth bar of this andante) is heard only too often given out as a 'passage' for the left hand; the figure should be delivered caressingly—it should be an amorous violoncello solo. In this manner Liszt played it, but gave out in fearful majesty the outbursts of octaves on the second subject in C major, that Henselt calls the 'Ten Commandments'—an excellent designation. And now, as for menuetto capriccioso and rondo of the sonata. How shall I describe what Liszt made of these genial movements on a first acquaintance? How he treated the clarinet solo in the trio of the menuetto, and the winding of the rondo? How Liszt glorified Weber on the piano; how like an Alexander he marched in triumphant procession with Weber (especially in the 'Concertstück') through Europe, the world knows, and future times will speak of it."
