  • Patent number: 7312386
    Abstract: A resilient band holds a pick for a stringed musical instrument securely in contact with a thumb or finger of the instrumentalist. In one aspect this device appears as a ring that has been slit along its center line over a portion of its circumference, the slit then being separated to produce a Y-shape. The two arms and leg of the Y provide the pick with a three-point support that maintains stability of the pick against a finger in both strumming and plucking modes over a wide range of attack angles. The resiliency of the band serves to adapt to various fingers as well as to a variety of conventional picks according to the preferences of the user, including flat picks, thumb picks, and finger picks. Methods of manufacture are described.

  • Patent number: 6346662
    Abstract: Embodiments of an ergonomic stringed instrument pick are shown and described. The pick includes curved or depressed surfaces generally conforming to the shape of the thumb and index finger that grasp the pick. Preferably, the pick includes a depressed area on one side of the pick near the front tip of the pick for receiving the tip of the index finger, and includes a hump rearward of that depressed area for contacting the first joint area of the index finger. Preferably, the opposite surface of the pick includes a depressed area near the rear end of the pick for receiving the pad of the thumb, and includes a hump nearer the tip or the pick against which the thumb, in effect, pushes or braces. These features preferably take the form of a generally S-curved pick, with both the bottom surface and the top surface making two curves to form the desired shape, which reduces hand and wrist strain due to the increased comfort, and provides a more sure grip of the ergonomic shape.
