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 a3 well. One possible method of achieving this clarification-would be an. historical analysis of the division as it occurred an music production and of the roots of the two main spheres. Since, however, the present study is concerned with the actual function:of popular music in its present status, it is more advisable to follow the line:of characteriza* tiqn of Jhe phenomenon itself as it is given today .than to trace it baclTto its origins. This is the more justified as the division into the two spheres of music took place in Europe long before American popular music arose. American music from its inception accepted , the division as something pre-given, and therefore the historical v background of the division applies to it only indirectly. Hence we seek, first of all, an insight into the fundamental characteristics of ■ -popular music in the broadest sense.. A clear judgment concerning the relation of serious music to popular music can be arrived at only by strict attention, to- the fu^amentalj&axacteristic of popular musicjj^a^^rd^tion.y^ The ' .'■ "Hi" b»«ic importance of »t*ndar
