Technology Vocational Institutions have long implemented the general course (or gerenal electives) program. For many years, students' attitude towards choosing an elective have become more initiative, choosing according to one's own interest and needs, hoping to acquire knowledge in different fields through these general courses. Students in the Early Childhood Education department and Music department take "Early Childhood Music" as a subject in order to learn how to teach young children music and make music with them when they become teachers in future, but, for those students who are in other unrelated departments, it may seem totally irrelevant. But for these students, who might become future parents, this course will be able to give them ideas to communicate with their young children through musical activities taught in this course, especially when today's society emphasises strongly on parental education. Therefore, "Early Childhood Music" has surpassed its role as merely a course to teach future teachers how to teach their young students in kindergartens and nurseries to an essential path for learning parent-child communicational skills. This dissertation, driven by the current social trend, gives an account of the significance of Technology Vocational Institution students, who are not in the related field, taking "Early Childhood Music" as a general course, schools and students may use this as a reference to the offering and selecting of a course.
