👉 Extemporising is a form of improvisation or creative expression in which an individual performs a piece of music, song, play, dance, etc., without having rehearsed beforehand. This can be done spontaneously or as part of a performance, and it often involves spontaneous lyrics and expressions that are not prepared beforehand. Extemporizing can be seen as a form of self-expression, as well as a way to challenge conventional wisdom and expectations.
