This article demonstrates the potential, importance and benefits of integrating formal and informal music knowledge into education and everyday life. Its primary purpose is to promote the use of music for the benefit of the individual and the wider society. The examples presented also reflect the connection of the author's fieldwork, research and teaching work, and his active role. The first example deals with the research of the Thai song Chang, Chang, Chang and its use in education, and later on in the cooperation between the University of Ljubljana (Slovenia) and Chulalongkorn University (Bangkok, Thailand). The second example presents the magnitude of the project Let's give them a song (2008). Based on a study on musical life in Slovenian homes for the elderly, the latter influenced the international project Inclusion Cocktail, step II (2013), and together with the research findings of the author's dissertation, this brought about the film Be Different, for which Slovenj Gradec Third Elementary School won the Video S-factor international competition (2017).
