A shaker typically consists of a hollow body filled with loose small elements. The materials vary depending on the culture, musical tradition, or desired use:
β Wood, bamboo, wicker, or gourd for traditional shakers
β Plastic or metal (aluminum, steel) for modern models
β Shapes can be cylindrical, egg-shaped, tubular, or even double-spherical
The body material, type, and density of the inner elements (metal beads, rice grains, sand, glass beadsβ¦) greatly influence the tone and texture of the shakerβs sound.
