This is certainly not a good piano music in the traditional sense, but more like an experimental musical work describing emotions.
The music repeats the four chords from beginning to end, which can be understood as the continuous cycle of daily monotony in our lives.
The change of the piano is mainly reflected in the right hand part, but no matter how the melody changes, the overall mood is still depressed.
It is difficult to explain the practical significance of music, but friends who can understand it naturally can understand it.
这肯定不是一首传统意义上好听的钢琴音乐，更像是一首描述情绪的实验音乐作品。
音乐从头到尾就4个和弦不断重复，可以理解为我们生活中每天单调的不断循环。
钢琴的变化主要体现在右手的部分，但无论旋律怎么变，整体的情绪依旧是压抑的。
很难去解释音乐的现实意义，但是能听懂的朋友自然能听懂。
