Dadaism was a reaction against the traditional values and conventions of art, and it sought to challenge and subvert these norms.

Dadaists often used chance and improvisation as a way to break free from traditional artistic conventions and to create new and unexpected forms of art.

Chance and improvisation allowed Dadaists to break free from traditional artistic conventions and to create new and unexpected forms of art that reflected their own unique perspectives and experiences.

Marcel Duchamp was a prominent Dadaist artist who is known for his use of chance and improvisation in his works. One of his most famous works, 'The Bride Stripped Bare by Her Bachelors, Even' (also known as 'The Large Glass'), was created using a variety of chance techniques, such as throwing pieces of glass at the canvas.

Dadaism had a profound impact on the development of modern art, and it helped to pave the way for the rise of abstract expressionism, pop art, and conceptual art.
