They say that writing about music is like dancing about architecture. But why don’t we dance to paintings—or for that matter, buildings—anyway? The latest research hints at why. According to a study,(16)music and dance share a parallel expression of emotion. It suggests that the two disciplines can express a mood together, with complementary methods of generating the dynamics of feeling. The intuitive link between our feelings and movements is so strong that even the word "emotion" includes the word "motion."(17)And across cultures, the three-way connection between music, motion and feelings is maintained, such that being "moved" by either feelings or music is not just a concept of English-speaking people. The dynamic features of emotion expression are cross-culturally universal. So what does this tell us about what music and dance are "for"?(18)Painting and sculpture can evoke emotion, but not the contagious type that tends to unify a group. The visual arts may well evoke great feeling in us, but they don’t make us really move, not like music can. Nearly all music may sound like someone moving about us, but dance music in particular probably sounds like someone engaging in a much more infectious behavior, one that in real life we might join. The study’s authors suggest that music may have evolutionary functions that aid survival, from "the soothing power of lullabies and the stimulating, synchronizing force of military marching rhythms" that can bind parents and children or entire nations together. The power of music may indeed be in its ability to move us, both literally and figuratively.
