This sonata is called by the Austrians the “Moonlight Sonata,” and this has become the popular name in America. It is said to have been written by Beethoven when he was recovering from the disappointment of his hopes in a love-episode that had an unfortunate termination. (See Marx’s “L. v. Beethoven, Leben und Schaffen.” From this magnificent work of Art-Criticism, I have drawn the outlines of the following interpretation.) The object of his affection was a certain young countess, Julia Guicciardi; and it appears from Beethoven’s letter to a friend at the time (about 1800) that the affection was mutual, but their difference in rank prevented a marriage. When this sonata appeared (in 1802) it was inscribed to her. _Adagio._ The first movement is a soft, floating movement, portraying the soul musing upon a memory of what has affected it deeply. The surrounding is dim, as seen in moonlight, and the soul is lit up by a reflected light—a glowing at the memory of a bliss that is past. It is not strange that this has been called the Moonlight Sonata, just for this feeling of borrowed light that pervades it. As we gaze into the moon of memory, we almost forget the reflection, and fancy that the sun of immediate consciousness is itself present. But anon a flitting cloudlet (a twinge of bitter regret) obscures the pale beam, or a glance at the landscape—not painted now with colors as in the daytime, but only _clare-obscure_—brings back to us the sense of our separation from the day and the real. Sadly the soft gliding movement continues, and distant and more distant grows the prospect of experiencing again the remembered happiness. Only for a passing moment can the throbbing soul realize in its dreams once more its full completeness, and the plaintive minor changes to major; but the spectral form of renunciation glides before its face, and the soul subsides into its grief, and yields to what is inevitable. Downward into the depths fall its hopes; only a sepulchral echo comes from the bass, and all is still. Marx calls this “the song of the renouncing soul.” It is filled with the feeling of separation and regret; but its slow, dreamy movement is not that of stern resolution, which should accompany renunciation. Accordingly we have _Allegretto._
