The inner part includes at least one supporting string core. At least in a specifiable length section of the musical string, the inner part boundary line has at least one curved, convex boundary line section. The inner part cross section of the inner part has a width which is greater than a height of the inner part cross section in perpendicular relation to the width. ## Claims ### Claim 1 A musical string, in particular a string instrument musical string, said musical string having a substantially circularly-cylindrical outer contour and comprising an inner part including at least one supporting string core and having an inner part cross section which is delimited by an inner part boundary line having a first curved, convex boundary line section at least in a predefined length section of the musical string, said inner part cross section defined by a width and a height in perpendicular relation to the width, with the width being greater than the height. ### Claim 2 (depends on 1) The musical string of claim 1, wherein the width is at least 110%, in particular at least 120%, of the height. ### Claim 3 (depends on 1) The musical string of claim 1, wherein the inner part boundary line has a second curved, convex boundary line section. ### Claim 4 (depends on 1) The musical string of claim 1, wherein the inner part has a mass center of gravity in spaced-apart relation to a center point of the outer contour. ### Claim 5 (depends on 1) The musical string of claim 1, wherein the inner part cross section of the inner part has a first axis of symmetry. ### Claim 6 (depends on 5) The musical string of claim 5, wherein the inner part cross section has a second axis of symmetry. ### Claim 7 (depends on 6) The musical string of claim 6, wherein the second axis of symmetry extends in perpendicular relation to the first axis of symmetry. ### Claim 8 (depends on 3) The musical string of claim 3, wherein at least one half of the first boundary line section and/or the second boundary line section is formed as a conical section line, in particular as a circular arc, hyperbola, parabola, and/or ellipsoid arc. ### Claim 9 (depends on 3) The musical string of claim 3, wherein at least one member selected from the group consisting of the first boundary line section and the second boundary line section is defined by a first radius of curvature at a first point of the member and by a second radius of curvature at a second point of the member, which second point is different from the first point, said first radius being different from the second radius. ### Claim 10 (depends on 1) The musical string of claim 1, wherein the inner part cross section of the inner part has a substantially elliptical inner part configuration. ### Claim 11 (depends on 1) The musical string of claim 1, wherein the inner part cross section of the inner part has a substantially barrel-shaped configuration. ### Claim 12 (depends on 1) The musical string of claim 1, wherein the inner part cross section of the inner part has a substantially oval, in particular egg-shaped configuration. ### Claim 13 (depends on 1) The musical string of claim 1, wherein the inner part boundary line has at least one linear section, in particular two linear sections, preferably in parallel relation. ### Claim 14 (depends on 3) The musical string of claim 3, wherein the inner part cross section of the inner part is bordered by two parallel linear sections of essentially equal length, said two parallel linear sections being connected on both sides by the first and second curved, convex boundary line sections. ### Claim 15 (depends on 14) The musical string of claim 14, wherein at least one transition between one of the linear sections and at least one of the first and second curved, convex boundary line sections is formed as an edge. ### Claim 16 (depends on 14) Musical string of claim 14, wherein at least one transition between one of the linear sections and at least one of the first and second curved, convex boundary line sections has a specifiable rounding. ### Claim 17 (depends on 1) The musical string of claim 1, further comprising an outer winding layer having at a first winding element which is wound in a helical line around the string core. ### Claim 18 (depends on 17) The musical string of claim 17, further comprising a further winding layer arranged between the string core and the outer winding layer. ### Claim 19 (depends on 18) The musical string of claim 18, wherein the inner part comprises the string core and at least one of the outer and further winding layers. ### Claim 20 (depends on 1) The musical string of claim 1, wherein the string core is designed as a single wire, as a wire cable, as a plastic fiber bundle, or as natural gut. ### Claim 21 (depends on 18) The musical string of claim 18, further comprising a preferably polymeric bonding and/or damping layer arranged between the inner part and an adjoining one of the outer and further winding layers.
