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:
– Wood, bamboo, wicker, or gourd for traditional shakers
– Plastic or metal (aluminum, steel) for modern models
– 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 beads…) greatly influence the tone and texture of the shaker’s sound.
