Dance improvisation has been a methodological tool for accumulation of choreographic material for the staged works throughout the 20th century, although different improvisation approaches emancipated into autonomous stage works and formats with the development of artistic practices and dance competences of the spectators (mostly in the developed dance contexts and systems). - In the republics of former Yugoslavia dance improvisation had been a constant methodological tool in the paradigm of expressionist and modern dance, with the performances of Jasna Knez (Slovenia) and some others it became also an autonomous dance practice. Its elements were present in the procedural works of Croatian collective KASP and choreographer Milana Broš in the 1960s and 1970s and choreographic compositions of En-Knap and Iztok Kovač in the 1990s, where improvised parts were especially emphasized as such. In the last two decades dance improvisation extended and developed into different performative formats (Festival Improspections, Croatia, Neforma, Slovenia etc.) and communal practices of gathering (different half-professional and non-professional contact improvisation collectives in Slovenia). Different skills of dance improvisation became a potential for development of different open works in the field of contemporary dance in the last decade or two. (R. V., 13.4.2026)
