Abstract
The invention relates to a string (1) for a stringed, bowed musical instrument, for example a bowed musical instrument like violin, viola or cello. The string has a first, load bearing core (10) and a winding strand (100) wound around the first core in helical windings. A damping agent (40) suitable for vibration damping is arranged in a profiled recess (150) in the winding strand. The recess is functioning as a reservoir between the first core and the winding strand. The reservoir is containing and/or retaining the damping agent so as to, at least, reduce dissipation of the damping agent through a gap between the adjacent helical windings of the winding strand. The invention results in a longer lifetime with optimum acoustic properties of the string.
