Symphony No. 40 in G minor (K.550) is the most cherished work in Mozart's music. It is a model of pure music that transcends all eras and one of the truly perfect masterpieces in the entire history of music. In this piece, Mozart uses the rare G minor key, which gives people a sense of desolation, but the throbbing and leaping theme of the first movement still has youthful vitality. The second movement is in sonata form, with a clear, peaceful and lyrical theme, but the restless and pulsing elements that flash in it imply melancholy. The minuet has a strong rhythm, resolute and severe, which is very different from the ordinary minuet. The three-note middle dance melody is delicate and caressing, like bright sunshine. The Allegro of the final movement is full of feverish humor, and its theme is somewhat tragic. Although the second theme is singing, there is a sad chord in the middle that collides with each other, and the ending ends in the dark key of G minor.
The first movement of the previous song is used here. In fact, SHE is a band that is good at plagiarism. The main melody in "Persian Cat" is the melody of the chorus of a famous orchestra, which is "Persian Market".
