But the absence of visible hardware does not mean the instrument is simple. It is a carefully tuned air chamber and a resonant panel, and every part of its construction affects the sound you get.

This dual nature is what gives the cajon its versatility. A cajon without snares sounds like a wooden box drum - warm, deep, and throaty.
