Expanding beyond conventional dance frameworks, this handbook looks at the ways that dance improvisation practices reflect our ability to adapt, communicate, and respond to our environment. Throughout the handbook, case studies from a variety of disciplines showcase the role of individual agency and collective relationships in improvisation, not just to dancers but to people of all backgrounds and abilities. In doing so, chapters celebrate all forms of improvisation, and unravel the ways that this kind of movement informs understandings of history, socio-cultural conditions, lived experience, cognition, and technologies.
