Collective improvisation is a type of improvisation where multiple individuals work together to create a spontaneous performance. It is often used in the arts, such as in dance and music, and requires a high degree of coordination and communication between the performers. Collective improvisation can be characterized by highly unspecific goals and the use of generative actions or performance events.

Positive aspects of collective improvisation include the creation of a unique and spontaneous performance that is not constrained by pre-planned movements or compositions. It also allows for the development of skills that support spontaneous ensemble dance making.

Negative aspects of collective improvisation may include the need to give away a degree of individual autonomy in service of the group. Additionally, collective improvisation may not always result in a conventional melody, which may be difficult for some listeners to appreciate.

Ingredients or materials are not applicable to collective improvisation as it is a performance art that relies on the skills and creativity of the performers.
