A drum shell is the hollow, cylindrical body of a drum that produces sound when struck. It is typically made from materials like wood, metal, or acrylic, which influence the drum's tone and resonance. The shell is an essential component of various types of drums, including snare drums, bass drums, and tom-toms. The thickness and shape of the drum shell can affect its sound quality and projection. Thicker shells tend to produce a louder, more focused sound, while thinner shells offer a warmer tone. The shell is often finished with paint or a veneer, enhancing its appearance and protecting the material.
