Soundboard

 

the part of the body of certain stringed instruments that intensifies and radiates the sound. Sounding boards are usually cut radially from resonant woods like fir and spruce, although in some instruments, like the gidzhak (Central Asian stringed instrument) or banjo, they are made of leather or a bladder. The vibration of the strings is usually conveyed to the soundboard through the bridge of the instrument. Instruments like the violin and guitar have two soundboards, an upper one that has soundholes cut into it for more resonance and a lower one. The soundboard of a piano is a sheet of glued pieces of wood, placed inside the instrument beneath the strings.
