Assessment in music appreciation is not a matter of ranking, but rather an interpretationof some form of expression of what students have heard. Such interpretationcan be based on visual evidence. The objective of the present study is to establish amethod for using visual image of students while they hear music in the teaching and assessmentof music appreciation. Students listened to music and were instructed to drawwhat they felt using colors, lines, and shapes. Polyphonic music was most suitable forteaching and assessment. By classification and interpretation of students' drawings, it isclear that their expressions represented important elements of polyphonic music that canbe expressed visually. By showing students' drawings to other students, teachers are ableto guide students to a greater understanding of musical structures and styles.
