Beethoven suddenly broke off the C minor Symphony to write the Fourth Symphony at a single sitting without his usual sketches. Happiness had come to him. In May 1806, he was betrothed to Theresa von Brunswick.[24] She had loved him for a long time—ever since as a young girl she had taken piano lessons from him during his first stay in Vienna. Beethoven was a friend of her brother Count Franz. In 1806 he stayed with them at Martonvasar in Hungary, and it was there that they fell in love. The remembrance of these happy days is kept fresh by some stories in some of Theresa's writings.[25] "One Sunday evening" she says, "after dinner, with the moon shining into the room, Beethoven was seated at the piano. At first he laid his hands flat on the keyboard. Franz and I always understood this, for it was his usual preparation. Then he struck some chords in the bass and slowly with an air of solemnity and mystery drifted into a song of John Sebastian Bach: 'If thou wilt give me thy heart, first let it be in secret, that our hearts may commingle and no one divine it.[26] My mother and the priest had fallen asleep and my brother was dream gazing whilst I who understood his song and his expression, felt life come to me in all its fullness. The following morning we met in the park and he said to me, 'I am now writing an opera; the principal character is in me and around me wherever I go. Never before have I reached such heights of happiness; I feel light, purity and splendour all around me and within. Until now I have been like the child in the fairy story, picking up pebbles along the road without seeing the beautiful flower blossoming close by.'... It was in May, 1806, that I became betrothed to him with the ready consent of my dear brother Franz."

The Fourth Symphony composed in this year is a pure fragrant flower which treasures up the perfume of these days, the calmest in all his life. It has been justly remarked that at this time "Beethoven's desire was to reconcile his genius as far as possible with what was generally known and admired in the forms handed down by his predecessors.[27]"

The same conciliating spirit springing from this love re-acted on his manners and his way of living in general. Ignaz von Seyfried and Grillparzar say that he was full of life, bright, happy and witty, courteous in society, patient with tedious people and careful in his dress. Even his deafness was not noticed, and they say that he was in good health with the exception of his eyesight, which was rather weak.[28] This strikes one in looking at Mahler's portrait of him painted at this time, in which he is represented with an elegance unusual for him and a romantic, even slightly affected look. Beethoven wishes to please, and rather fancies himself in doing so. The lion is in love; he draws in his claws. But one feels deep beneath under all this playfulness, the imagination and tenderness of the Symphony in B flat, the tremendous force, the capricious humour and the passionate temper of his nature.

This profound peace was not destined to last although love exercised its soothing influence until 1810. Beethoven doubtless owed to it the self-mastery which at this period enabled him to produce some of the most perfect fruits of his genius; that great classical tragedy, the Symphony in C minor and that delicious idyll of a summer's day: the Pastoral Symphony, 1808.[29] The Sonata Appassionata, inspired by Shakespeare's Tempest,[30] the Sonata which he himself regarded as his most powerful one, appeared in 1807 and was dedicated to Theresa's brother. To Theresa herself he dedicated the dreamy and fantastic Sonata in F sharp, Opus 78 (1809). An undated letter[31] addressed to his "Immortal Beloved" expresses the intensity of his love no less strongly than does the Sonata Appassionata.

July (1801).

"My Angel, my all, my very self.

Just a few words to-day—and indeed in pencil (with thine). Only till to-morrow is my room definitely engaged. What an unworthy waste of time in such matters! Why this deep sorrow where necessity speaks? Can our love endure otherwise than through sacrifices, through restraint in longing? Canst thou help not being wholly mine? Can I, not being wholly thine? Oh! gaze at nature in all its beauty, and calmly accept the inevitable—love demands everything, and rightly so. Thus is it for me with thee, for thee with me, only thou so easily forgettest that I must live for myself and for thee. Were we wholly united, thou wouldst feel this painful fact as little as I should. My journey was terrible. I arrived here only yesterday morning at four o'clock, and as they were short of horses, the mail-coach selected another route; but what an awful road! At the last stage but one, I was advised not to travel by night; they warned me against the wood, but that only spurred me on, and I was wrong; the coach must needs break down, the road being dreadful, a swamp, a mere country road; without the postillions I had with me I should have stuck on the way. Esterhazi, by the ordinary road, met the same fate with eight horses as I with four—yet it gave me some pleasure, as successfully overcoming any difficulty always does. Now for a quick change from without to within; we shall probably soon see each other; besides, to-day I cannot tell thee what has been passing through my mind during the past few days concerning my life. Were our hearts closely united I should not do things of this kind. My heart is full of the many things I have to say to thee. Ah! there are moments in which I feel that speech is powerless. Cheer up. Remain my true, my only treasure, my all!!! As I to thee. The gods must send the rest; what is in store for us must be and ought to be.

Thy faithful

Ludwig."

It is difficult to divine what was the barrier which separated these two from the consummation of their love. Was it the lack of fortune or the difference in social position? Perhaps Beethoven rebelled against the long period of probation which was imposed on him or resented the humiliation of keeping his love secret for an indefinite period. Perhaps, impulsive and afflicted as he was, a misanthrope too, he caused his loved one to suffer without wishing it and gave himself up to despair in consequence. The fact remains that the engagement was broken off, although neither seems ever to have proved faithless.

Even to her last day (she lived till 1861) Theresa von Brunswick loved Beethoven, and Beethoven was no less faithful. In 1816 he remarked, "When I think of her my heart beats as violently as on the day when I first saw her." To this year belong the six songs, Opus 98, which have so touching and profound a feeling. They are dedicated "To the loved one far away" (An die ferne Geliebte). He wrote in his notes, "My heart overflows at the thought of her beautiful nature; and yet she is not here, not near me!" Theresa had given her portrait to Beethoven, inscribed, "To the rare genius, the great artist, the generous man. T.B."[32] Once during the last year of his life a friend surprised Beethoven alone, and found him holding this portrait and speaking to himself through his tears: "Thou wert so lovely and great, so like to an angel!" The friend withdrew, and returning a little later found him at the piano, and said "To-day, my old friend, there are no black looks on your face." Beethoven replied "It is because my good angel has visited me." The wound was deep. "Poor Beethoven" he said to himself, "there is no happiness for you in this world; only in the realms of the ideal will you find strength to conquer yourself."[33]

In his notebook he wrote, "submission, complete submission to your destiny. You can no longer live for yourself, only for others. For you there is happiness only in your art. O God, give me strength to conquer "myself"."...
