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.
