  • Patent number: 7723595
    Abstract: A sheet music holder having a golpe board with a non-porous surface for gluing into a guitar body with a porous surface, a twist lock power-assisted suction device, a clamp with a single tightening nut, and a sheet tray to hold the sheet music. The twist lock power-assisted suction device allows a user to easily create a strong vacuum attachment that will last fro hours so a complete performance will not be interrupted. The golpe board is included where the guitar body has a porous surface that would otherwise frustrate the suction attachment. The double-ball-and-socket clamp and arm allows a variety of positioning possibilities for the user to best read the sheet music in the tray.

  • Patent number: 5509341
    Abstract: A thumb pick for a stringed instrument is provided. The thumb pick includes a thumb engaging portion for coupling the pick to the user's thumb. The engaging portion comprises a bottom portion and an arcuate portion that extends above the bottom portion. The arcuate portion and bottom portion substantially encircle the thumb when the pick is coupled thereto. The bottom portion comprises a planar surface lying within a thumb plane that extends generally parallel to the longitudinal axis of the thumb. A pick portion is adjacent to the bottom portion and lies generally within a pick plane. The pick portion is dimensioned to engage a string of a musical instrument when the pick is coupled to the thumb. An intermediate portion integrally couples the bottom portion to the pick portion. The intermediate portion is located adjacent to the end of the arcuate portion to engage the thumb when the pick is coupled thereto.
