In this article, I bring together research from ethnomusicology, ecology, neuroscience, ‘4E’ cognition theory and evolutionary musicology in support of the idea that musicking, human musicking in particular, can best be understood as an emergent ecological behaviour. ‘Ecological’ here is used to mean an active process of engaging with and connecting ourselves to our various environmental domains – social, physical and metaphysical – and although I will focus on musicking, these concepts may apply to other artistic behaviours as well.
