Nowadays, due to globalisation and the opening of European frontiers, French companies are more and more interested in having their employees trained in foreign languages. However, despite the array of methodologies that exist in this field, trainers are still trying to find THE way to motivate the trainee and to incite him to become fully engaged in the language learning process. It is in this context that we introduce an innovative training sequence in which music plays a central role. The aim of this research is to conduct an inquiry into the potential efficiency of such an approach from a pedagogical systems design perspective. This study shows the motivating aspect that music can get in English as a foreign language training. Translated from French by Pascal ARCHIMEDE.
