This paper is an approach to the concept of musical folk language in relation to folk music. We consider musical folk language an ability of human to have an intense emotional life, to live deeply feelings, impressions, situations. Affectivity is aimed at studying the compartment of emotional feelings specific to the creation, interpretation and reception of musical artistic values. By knowing popular music and musical folk language among students we not only meet a development of the student's personality on certain fronts of certain disciplines or areas of culture, but we determine students to deepen their knowledge of national values, to operate constantly and uninterruptedly with these values. At the same time, the acquisition of national values determines a good management of emotions and an adherence to the content of ideas and feelings expressed through the songs of the Romanian people.
