Abstract
An improved sound post (4) for musical instruments with a swivel device (28a, 28b) at either end. They allow the flat ends (29a, 29b) to make full and even contact with the inner surfaces of the top (21) and back (22) of the musical instrument. The invention has also a method of adjusting the length in a simple manner and appears to be a traditional sound post to most observers. A master craftsman is not required to properly fit and install it and traditional tools are used. Because of the enhanced fit the tone and playability of the instrument improve dramatically. The danger of sound post cracks is significantly reduced as the ends (29a, 29b) make full and even contact even if the sound post (4) is jarred well out of position.
