One night, Chopin played this piece alone in the house. While he was deep in thought, he suddenly had a hallucination and felt a procession of Polish warriors and ladies invading his room. So Chopin panicked and ran out of the room and didn't come back all night.

The Polonaise-fantaisie in A-flat major, Op. 61 (The Polonaise-fantaisie in A-flat major, Op. 61) is the last Polonaise, completed around 1845 to 1846 It belongs to Chopin's mature period, so it is also considered to be one of Chopin's best representative works. But this view only gained widespread consciousness among musicians in the 1930s. Because the structure of this work is relatively complex and not so clear, although it can be regarded as a trilogy overall, there are endless themes and musical ideas in the music. On the other hand, this piece of music is called "Polonaise-Fantaisie", or "Polonaise-fantaisie", so it has a greater fantasy component, with improvisational ideas and beautiful melody, and The delicate rhythms are intertwined, without the usual simple and obvious contrast of musical images. The themes are very similar in tone and mood, but contrast with the melancholy fantasy and dramatic elements.

Chopin was 36 years old when he composed "Fantasy Polonaise in A flat major". His homesickness for being far away from his motherland, his long-term and severe lung disease, and his growing emotional rift with George Sand all deepened. relieved his depression and pain. Therefore, what we can feel in this piece of music is Chopin's complex thoughts. There is an unwillingness to fight in sadness, but it still ends in despair.
