In 1801, Beethoven composed the piano sonata after experiencing emotional ups and downs. After listening to it, the German poet Ludwig Leerstable compared the first movement of this piece to "like playing in Lucerne, Switzerland." "Like a small boat swinging on the lake where the moonlight shines", the song was named "Moonlight Song".

The words "as if covered with silver gauze" and "quiet" in the article describe the beautiful scene in the thatched hut under the clear moonlight. Such beauty outweighed the poverty and desolation in the hut. Beethoven "looked at" the poor brother and sister and expressed his deep sympathy.

This situation made Beethoven think that beautiful music should be given to poor people who love music, just like the quiet moonlight shining into thatched hut. This association made him pick up the piano keys.

The shoemaker listened to Beethoven's music and thought of the beautiful moon rising over the sea.

Under the clear moonlight, everything is so hazy, beautiful, elegant and quiet. Such beauty outweighed the simplicity and desolation of the hut. Beethoven was deeply moved by this situation. He "looked at" the poor brother and sister, and his sympathy arose spontaneously. Yes, beautiful music should also be given to poor people who love music. Thinking like this, he couldn't help but press the keys.

Although the accompaniment, theme and intensity have not changed much, the fluctuations of the author's heartstrings are still delicately expressed through changes in harmony, register and rhythm. This sonata contains Beethoven's most original ideas. Its dream-like improvisational nature and the way it explores the sound of piano sounds anticipated Debussy's Impressionism about a hundred years later.

The theme it is based on is very simple: at the beginning of the music, boundless fantasy is constructed by the continuous flow of triplets. Four bars later, the first theme appears faintly in the alto area. It is delicate and calm, with a hint of melancholy. The second theme appears in the key of B major at 1 minute and 18 seconds in section 1. The middle part begins with the first theme.

After a short expansion, the inner excitement became even stronger. At the end, when the boiling enthusiasm reached its peak, it suddenly fell silent, but the turbulent mood did not calm down. Beethoven once said that both sonatas in his Opus 27 were like fantasias.

He instructed that the movements of the Piano Sonata No. 14 in C sharp minor should be followed without a pause, so that the beginning movement could gradually unfold in a suggestive way and enter the intricate final movement, thus providing A feeling of condensed orgasm.
