Mozart and Chopin were not musicians of the same period, so the music styles they represented were quite different. Mozart was born at the end of 18, which was the heyday of Vienna classical music school. Because among Mozart's many works, opera is the most outstanding. Chopin was born in the first half of the19th century, and his works are all piano music. This period was The Romantic Period, and Liszt and others in the same period all had this style. There are many resumes about them on the internet, so I won't say much. You can check them as much as possible. On the similarities and differences, my personal understanding is this: both are beyond the music itself, and this top-down technique can be said to be the same thing. Musically, I don't think we can sum up the same points. ) the difference is easy to say. Let's compare the piano works. During the Baroque period, the production technology of the piano itself was limited, and the deep technical support had not been developed. Keyboard music is mostly composed of simple melodies and intervals. You can play faster, but the phoneme span is not big, and there are not many places for lame hands. The melody is simple and beautiful, revealing an elegant and noble temperament and Mozart's personal naughty personality. At that time, there were no rich modes and chords, no fancy tone sandhi and no complicated musical structure. In The Romantic Period, with the further expansion of secularization of music, keyboard music gradually went out of the court and church and flowed into the people. The piano manufacturing process is improved, and the sound effect and keystroke speed are improved. With the rapid development of music theory and the continuous expansion of musical forms and chords, the musical effect of keyboard music has changed greatly, and many scales, chords, transpositions, modes, chord connections and so on that could not be used before can be used. This brings more possibilities and changes to music creation. Chopin's own experience also determines his unique characteristics in music creation. Romance, poetry, passion, justice and so on are all reflected in him. The richness of musical emotion needs the follow-up of playing techniques. Complex playing methods and techniques have emerged. Only Chopin can write etudes so beautifully and passionately. Chopin also wrote ballads, scherzos, preludes, Mazzuca's boat songs and Polonaise's works. This is what Mozart didn't have. They have too much to write, but listening to their works will make you understand these things better.
