The sound post of a violin
The sound post is a small wooden dowel wedged inside the violin between the top and back, just behind the bridge. Despite its size, it is crucial: it transmits vibrations between the plates and strongly affects the instrument's tone and response. In French it is called 'l'âme', the soul, reflecting its importance. A skilled maker or repairer adjusts its exact position by tiny amounts to bring out the best sound, and even a small shift can change the voice of the instrument. On historic violins such as a Stradivari, the fitting of the sound post is part of the careful set-up that lets a centuries-old instrument perform at its best in the concert hall.
