发明名称 FIXED FINGERING DEVICE FOR FRETTED STRINGED MUSICAL INSTRUMENT
摘要 An inventive fixed fingering device adapted to secure a string of a guitar or other fretted stringed instrument at selected fret positions in order to quickly and easily vary the length of the string available for vibration to change the pitch when the string is plucked. The fixed fingering device describes a rectangular shaped block having formed through its width a transverse partial cylinder whose cylindrical side is open to the bottom of the device, the partial cylinder adapted to encompass and be secured to a selected fret on the fretboard, the transverse partial cylinder and the fret so shaped as to complement each other. In addition, lengthwise through the fixed fingering device is an opening through which is passed one of the strings. Lastly, a protruding lip is provided attached to the block shaped fixed fingering device to provide for lifting or levering the fixed fingering device off the fret by the operator's fingernail. A plurality of fixed fingering devices are provided, one for each of the strings. After use, the devices are slid down the string to rest at the string nut and out of the player's way.
