The soundpost is the dowel of wood that you see inside the treble (E or A) side of your violin, viola or cello. For a small piece of Spruce that's about 6mm thick (about 7mm on a viola, about 10mm on a cello) it makes a tremendous difference on how your instrument plays and sounds. In French, the soundpost is called "l'âme", the "soul" of the instrument. I completely agree.
