Rebetiko is a musical and cultural expression linked to song and dance that initially spread among the urban lower- and working-class populations in the early twentieth century. This school, located in the port city of Piraeus—which is one of the major urban areas where the genre emerged—was inspired by rebetiko to design a cross-curricular project in order to integrate it in the daily teaching of literature, English, physical education and ICT classes. Teachers used rebetiko to discuss gender stereotypes, and to improve students’ vocabulary and communication skills in a foreign language. Students enhanced their computer skills by developing a mobile app to raise awareness about this living heritage and to contribute to its safeguarding.
