acoustic bridge

In stringed musical instruments, a bridge is a crucial component made of elastic wood. Its primary function is to transmit the vibrations from the strings to the instrument's resonating body, known as the soundboard.12

There are two main types of bridges:
* Pressure bridges: These are found in instruments like the violin. The strings pass over the bridge, which is held in place by the tension of the strings.1
* Tension bridges: In instruments such as the guitar and lute, the string is attached to the bridge itself, and the bridge is glued to the soundboard.1

A small post, called a sound post, is also used in instruments like violins to support the bridge and help transmit vibrations to the back of the instrument. The soundboard amplifies the sound produced by the strings, and its characteristics significantly influence the instrument's tone.32
