1. "The Mark of Rain".

The falling rain hits the window sill, and my mood gradually sinks with the raindrops, until I am completely relaxed. There is no human voice, no instrumental music, the anxiety dissipates, and the eyelids close. It is the brainwave music that quickly enters shallow sleep. , there is no natural sound in the world that makes people feel more comfortable and calm than rain.

2. "Goldberg Variations".

The most recognized classical music in the world for treating insomnia is Bach's "Gothenburg Variations". The music is gentle, intellectual, sophisticated and natural. Bach is not a musician who drowns everything with emotion, but he can always place us in the vastness and infinity of human life.

3. "Moonlight".

With light pen and ink and simple tone, a picture of complete silence and moonlight washes out spontaneously. The beautiful melody filters out the impurities in the light cast by the moon. Imagine it is beautiful and picturesque, and it hangs brightly in your heart. Play the song "Moonlight" before going to bed, and your whole heart will be silent, carefree and undisturbed, and the world will become quiet under the piano keys.

4. "Sleepsong".

The music of the Secret Garden is ethereal, quiet and deep, purifying the soul, returning to nature, transparent and soft, melancholy and weak with strength, as if floating from a far away place, which can help meditation and the soul of cleanliness. The song "Sleepsong" is as its name suggests. Lying in bed and listening to the distant female voice, you will fall into a sweet dream without realizing it.

5. "Mysterious Song".

The French composer Satie was cynical throughout his life, and the classic he left behind is none other than "The Mysteries." Mysterious music has hypnotic properties as soon as it comes out. It is ethereal and clear, with an ancient oriental charm and a religious mystery.
