Pointillism /ˈpɔɪntᵻlɪzəm/ is a technique of painting in which small, distinct dots of color are applied in patterns to form an image. Georges Seurat and Paul Signac developed the technique in 1886, branching from Impressionism. The term "Pointillism" was first coined by art critics in the late 1880s to ridicule the works of these artists, and is now used without its earlier mocking connotation. The movement Seurat began with this technique is known as Neo-Impressionism. The Divisionists, too, used a similar technique of patterns to form images, though with larger cube-like brushstrokes.
The technique relies on the ability of the eye and mind of the viewer to blend the color spots into a fuller range of tones. It is related to Divisionism, a more technical variant of the method. Divisionism is concerned with color theory, whereas pointillism is more focused on the specific style of brushwork used to apply the paint. It is a technique with few serious practitioners today, and is notably seen in the works of Seurat, Signac and Cross. However, see also Andy Warhol's early works, and Pop Art.
Punctualism (commonly also called "pointillism" or "point music") is a style of musical composition prevalent in Europe between 1949 and 1955 "whose structures are predominantly effected from tone to tone, without superordinate formal conceptions coming to bear" (Essl 1989, 93). In simpler terms: "music that consists of separately formed particles—however complexly these may be composed—[is called] punctual music, as opposed to linear, or group-formed, or mass-formed music" (Stockhausen 1998, 452, bolding in the source). This was accomplished by assigning to each note in a composition values drawn from scales of pitch, duration, dynamics, and attack characteristics, resulting in a "stronger individualizing of separate tones" (Frisius 1994). Another important factor was maintaining discrete values in all parameters of the music. Punctual dynamics, for example
"The almost analytical focus on individual events, and then the transition between them, brings a stillness to this music far removed from the gestural quality of other pieces" (Grant 2001, 78). From a purely technical point of view, the term "punctual" has the sense of "a point of intersection of parameters" in serial music (Eggebrecht 1974).
