When it comes to being cynical and uninhibited, the classical music works are none other than Schubert’s. This is both Schubert's success and his frustration. The composer wrote approximately hundreds of songs, 15 string quartets, 21 piano sonatas, and 9 symphonies. Among them, the most popular ones are his "Trout Quintet", "Lullaby" and "Serenade", which are lively, humorous and warm. . His vocal suite "Winter Journey" has a high artistic level, but the whole piece is full of sorrow and grief. If it were in an era of economic downturn and difficult living standards, it would arouse quite a lot of cries. But as people become more understanding of history and rational about reality, such music seems to complain too much and have a narrow vision.
