soundboard

The soundboard, which the violinist holds, takes the vibration of the strings and projects it out as sound.

Figure 10 shows the layout of ribs, bridges, and strings on the soundboard.

The bridges served to direct the course of the strings and to conduct the sound waves to the soundboard.

Erard was the first to make it in two pieces of wood, generally sycamore, with the addition of a flat soundboard of Swiss pine.

Guitar or pizzicato notes are obtained by twanging the strings sharply at the lower end near the soundboard with the nails.

We now arrive at this joining of the wood for the soundboard, and the glue to be used must be of the best.
