Articulation, in art and architecture, is the way in which encounters and links between the different elements that make up a design are designed. There are various degrees of articulation, such that each part of a design can relate to the whole on a wide range of levels, from simple juxtaposition to high degrees of continuity and unity between the pieces. The articulation of a building reveals how the parts were linked to form the whole, by emphasizing each of them in a recognizable way. In highly articulated designs, each part is clearly distinguishable in itself.[1]​.

The opposite concept to the articulation of the parts is that of continuity and fusion, where the differentiation of the parts is minimized. An articulation of distinguishable pieces places emphasis on strategic breaks, while an articulation of continuity relies on subtle transitions.[2]​ Continuity (or fusion) minimizes the independence of the elements and puts the focus on the most important part of the whole, reducing attention on the other independent elements.[2]​.

The articulated form emphasizes the parts that make up a building, making them visually distinguishable. Sometimes, the reading ends up blurring the whole, fragmenting it into too many pieces, but generally the articulation seeks a balance between both extremes.

Architecture has been defined as “the art of articulating spaces.” And geometry is an architect's basic tool, but it is not his way of communicating. This shape is the definition of the objects in the space that surrounds them, in such a way that the articulation is “the geometry of the shape and space.”[3]​.
