Arte Informale: Arte Informale is a term coined in 1950 by the French critic Michel Tapié to refer to the art movement that began during the mid-1940s in post-World War II Europe.

Sometimes referred to as Tachism, Art Autre or Lyrical Abstraction, it was a type of abstraction in which form became less important than that of the expressive impulses of the artist, and was opposed to the rationalism of traditional abstraction.  The qualities of informal art explore the possibilities of gesture, materials (often non traditional), and signage as the basis of communication.  Oftentimes art characterized as informal is executed spontaneously and the approach to painting and sculpture are generally gestural, performative, expressionistic and experimental.  Certain artists such as Lucio Fontana, Alberto Burri and Emilio Vedova were crucial figures of this movement.
