Moonlight Sonata. German composer Beethoven composed it in 1801, also known as "Piano Sonata No. 14" and "Sonata in C Minor". The author dedicated it to his first lover, Juliet Chichardi. They had broken up at that time, and Beethoven was in great pain due to lovelorn love and ear disease. The work was created under such circumstances. After listening to the first movement, the German poet Lehrstab thought of the bright moonlight on Lake Lucerne in Switzerland. The publisher named the work "Moonlight" accordingly, and the author himself titled it "Sonata Fantasy". Not only is it full of the author's fantasy and exploration of life, but the structure of the work is also full of freedom and improvisation: for example, the tempo arrangement breaks the order of the fast and slow movements of the traditional sonata suite, and the three movements are designated as slow. Allegro, Allegro and Allegro excited.

The first movement is a trilogy. The music plays a cantabile theme against the background of slow long tones and constantly flowing triplet. The tranquility implies melancholy and depressed emotions. The entire movement is full of profound and touching rich emotions, delicately expressing the inner pain and fluctuations. .

The second movement is a complex trilogy, adopting the genre of minuet, and the melody is elegant, light and full of vitality. This is a transitional movement, which prepares for the entry of the first movement. It seems that the smile left in an instant temporarily relieves the sad heart.

The third movement is the climax of the whole piece and is written in sonata form. The main theme, such as uncontrollable conflict and passion, breaks out with dramatic effect. It is closely related to the second movement. But the emotions expressed are completely different; the theme of the deputy department is passionate and seems to be a complaint from the bottom of the heart. The continuous eighth notes at the end play a firm rhythm, showing impulsive enthusiasm and strong will. After entering the development department, my inner excitement became even stronger. At the end, when the boiling enthusiasm reaches its peak, a slow and long tone suddenly appears, and then falls silent again. After this, there is a more violent impact, and finally ends in two powerful chords, which seems to confirm that the will will finally overcome the grief and inner conflicts, thus proving that people will eventually win in the confrontation with fate.
