Abstract:
1. A weight relieving device for a woodwind musical instrument being played by a player who supports said instrument by conventionally positioning said player's right thumb against a lower surface of the instrument thumbrest, comprising: (a) a force potential source; (b) means for linking said force potential source to a snap-hook to exert on said snap-hook a pulling force to move said snap-hook to a point as close as possible to the center of said force potential source when allowed to; (c) said pulling force being calibrated to be always less than the force of the weight of the instrument by a calculated amount; (d) means for pivotably securing releasably said snap-hook to the upper surface of said thumbrest; (e) means for securing releasably an identifiable point of said force potential source a relatively fixed distance from a chosen body part of said player of the instrument; whereby, in all usual playing positions that point the instrument to the ground, said chosen body part will enable said pulling force to create physically a component force in line with but opposite to the gravity force of the weight of the instrument on said thumbrest, and thus will diminish said gravity force by an intended amount to provide a perceivable relief on the right thumb of said player.
