Dance is at the heart of diverse cultures around the globe, from the increasing popularity of salsa clubs, to break dance battles that gather crowds in the street, to the constant stream of dance routines going viral on TikTok. But behind the glitzy performances are amazing and unpredictable histories: the shocking debut of the waltz in eighteenth-century Vienna; the power of African-American influence on the jive and Lindy hop; and the early foundations of hip-hop in funk and disco styles. Tango, samba, Charleston, cha cha cha, rumba – each dance has distinct rhythms, quality of movement and complex rules to learn and follow. But they all shook up society and gave ordinary people the freedom of self-expression.
