For those who have never experienced inner pain, Bach's music is dull, monotonous and boring; Bach's music is a transparent, cool and sweet world for people who have suffered a lot. All Bach's music is a prayer for peace and a desire to live and work in peace. This kind of emotional appeal in the hearts of the German nation, which has experienced 30 years of war and the country has been politically divided for a long time, is bound to arouse a universal and strong * * * sound. People who like to listen to Bach's music all hope to get comfort and strength from Bach's music.
