Abstract: Expressing Feelings is the key to the Song Lyrics.The Appraisal theory provides a systematic approach to feelings.The paper, within the framework of the Appraisal theory, constructs an analytic framework and procedure of feelings in Song Lyrics.Feelings should be analyzed from types, polarity, strategies, participants and scales, and the feelings are distributed in discourse in ranks:micro-feelings,meso-feelings and macro-feelings.The deconstruction of feelings begins with foregrounding micro-feelings,then backgrounding micro-feelings with reference to meso-feelings and macro-feelings and ends with the fluctuation of feelings.The paper, using the model, analyzes the feelings in Li Qingzhao's "Slow, Slow Tune".
