Basic shoulder rest for 1/8, 1/4 and 1/2-sized violin or viola that has no-clamps that mute the violin's sound or stop the vibrations of wood. It increases the volume of sound, adds better quality with more "overtones", and is very comfortable, ergonomically designed and will not fall off. It provides a secure "hold" for the violinist or violist and attaches repeatedly, sticking without glue or clamps with no damage to varnish, edges or back of violin. The shoulder rest fits easily in the instrument case, and prevents the instrument from rattling. It also lessens and diminishes a musician's sores and marks on their chin, neck and collarbone, as it allows constant freedom, in contrast to rigid, vice like gripping shoulder rests. Blue colour.
