tessitural

Tessitural refers to the arrangement or pattern of tesserae, which are small, typically square pieces of stone, glass, or ceramic, used in mosaics. The term is most commonly associated with the art of mosaics, where tessitural describes the way these individual pieces are laid out and juxtaposed to create an image or pattern. The tessitural quality of a mosaic can greatly influence its overall appearance, texture, and visual impact. For example, a tight tessitural arrangement with small, closely packed tesserae can create a smooth, detailed image, while a looser tessitural approach with larger, more widely spaced pieces might lend a more rustic or abstract feel. The direction in which the tesserae are laid, their size, shape, and the grout lines between them all contribute to the tessitural effect. In a broader sense, tessitural can also be used to describe the textural qualities of any surface composed of small, discrete units, though its primary application remains within the context of mosaic art. Understanding the tessitural aspects is key to appreciating the craftsmanship and artistic intent behind a mosaic.
