This chapter examines the issue of musical sensibility as an instinct as well as the cognitive and neural capabilities that underlie musical expression, including diverse forms of memory. In particular, it considers working memory as an evolutionary trend that expanded our problem solving and social expression. The chapter first provides an overview of the link between musical sensibility and social instincts from an evolutionary perspective before discussing how music is inherently tied to movement and time, along with cognitive events, adaptation, sensory experiences, and emotional sensations. It also describes musical cognition and cognitive motor planning memory as inherent features of musical sensibility, and how musical experience affects the brain.
