I like music very much, pop songs particularly. Every evening then I am doing homework and at weekends when I at home, I always play some of my favorite songs on my tape recorder. The familiar patterns of notes attracts me into the colorfully world of music. Now and then I stopped to follow the songs. Sometimes, my mother comes in, asking me to fix my attention to my homework. She does not like the pop music. Like most grown-ups, she enjoys folk songs, because the peaceful music reminds her of their beautiful life when she was young. It is a truth which people of different age understand music differently and enjoy different kinds of music.
