Identify a technique commonly used in modern dance.

Improvisation is a widely recognized technique used in modern dance, as it allows dancers to express their emotions and creativity freely. Unlike structured dance forms, modern dance encourages spontaneous movement and exploration, enabling dancers to react to their environment, music, and their own physical sensations in real time. This flexibility promotes individual expression and often leads to unique and personal interpretations of movement, which is a hallmark of modern dance.

While choreography is an essential aspect of dance and involves planning and creating dance sequences, it does not capture the spontaneous nature that improvisation offers. Ballet and salsa, although important dance styles, have strict techniques and guidelines that contrast with the freer and more exploratory approach found in modern dance.
