ABSTRACT
Popular music, which produces the stimuli we are here investigating, is usually characterized by its difference from serious music. This difference is generally taken for granted and is looked upon as a difference of levels considered so well defined that most people regard the values within them as totally independent of one another. We deem it necessary, however, first of all to translate these so-called levels into more precise terms, musical as well as social, which not only delimit them unequivocally but throw light upon the whole setting of the two musical spheres as well.
