Abstract
A single reed woodwind ligature system has an upper U-shaped structure for contacting the upper portion of a mouthpiece at one or more small areas of contact and for engaging a lower structure, preferably by threaded ends and nuts. A reed contactor plate contacts a reed at a portion of its bottom curved surface. At least one ball bearing sphere is located in aligned cavities of the lower structure and the reed contactor in a spaced-apart configuration and forms a pivot mechanism capable of roll, pitch and yaw rotations in three dimensions around the approximate center of the at least one sphere. Embodiments include multiple spheres and sphere-bearing pin contact combinations forming the three-dimensional adjustable pivot. A retainer holds the spherical pivot components together when the ligature system is not clamping the reed to the mouthpiece without hampering user adjustments in the three normal (roll, pitch and yaw) dimensional ranges.
