The sounding board is the largest part of a string musical instrument's body. It produces sound by resonance. Most instruments have two sounding boards, an upper and a lower one. Some folk instruments have only one sounding board. An upper sounding board usually has some resonant holes in it. The holes can have different shapes; round in guitars, f-holes in violin family instruments, rosettes in lutes, and so on.

Sounding boards of some instruments have unique names, such as plate, or belly (the latter in a violin).
