difficult to understand classic orchestra
I often find it difficult to understand western classic orchestra, in my cd shelf, this kind of cd are the least to listen to.Somehow I just can not know what music is expressing, it can not evoke me any feeling. I want to know in UK, do you usually listen to such kind of music? It is a kind of cultural essence ,so do we must to know some background knowledge before we enjoy it ? For example , what happened when the composer composed the music, etc?
Bejing opera is famous, but I dont like it at all. What I always listen is pop, voilin, folk song ,jazz.......
What cd do you usually listen to? How can I appreciate the classic orchestra? What is the ture value of these music?
