Usually it refers to a movement in the arts, like Dadaism, or in politics, like anarchism. Avant-garde can also be used as an adjective to describe something that’s cutting-edge.
Avant-garde music is music that is considered to be at the forefront of experimentation or innovation in its field, with the term "avant-garde" implying a critique of existing aesthetic conventions, rejection of the status quo in favor of unique or original elements, and the idea of deliberately challenging or alienating audiences.
