The purpose of this paper is to explore the musical poetic imagination in "Island's Sunrise," which was the anthem for Sunflower Movement in Taiwan, by using phenomenological method to discuss with students in the general education curriculum. Poetic imagination theory is borrowed from the modern masters of psychology, M. Freud, and of phenomenology, M. Heidegger, who describe the process of the psychological dynamic revelation of the artwork. Both Freud and Heidegger think poets begin with the unknown, which are unconscious or open. Through the poetic imagination, people reveal the truth from their own experience and respond to the works of art as "I am what the poet sees." The discussion is followed by 4 processes of Clark Moustakas' phenomenological research methods. It starts from "Epoche," putting prejudgments aside and writing down personal intuition. Secondly, it uses "phenomenological reduction" method to help students understand the harmonic structure and the special "silent" moment of the song. The third process is imaginative variation by asking students to choose a sentence from the lyrics to analyze the intention and relating it to their own/individual experience. Finally, we integrate the former three processes to let the students understand the importance of poetic imagination in music and the strong affect social movement songs had on the people.
