The author considers that music is implicit in the first cries of the

child; when such cries are cathected with libido the foundation of music is laid. Rhythm, as a part of music, is to be traced back to the beginnings of walking rather than to the heart beat. Music, itself, begins not with rhythm but with melody, which is a form of the peep-bo game, which has its joy in the return of the known and desired object. Harmony has to do with mass psychology. Like dreams, musical creation is based on the wish.
