Hand by the ability to be brought opposite to the fingers, a muscle action known as opposition. The skeleton of the human hand consists of 27 bones: the eight short carpal bones of the wrist are organized into a proximal row (scaphoid, lunate, triquetral and pisiform) which articulates with the bones of the forearm, and a distal row (trapezium, trapezoid, capitate and hamate), which articulates with the bases of the five metacarpal bones of the hand. The heads of the metacarpals will each in turn articulate with the bases of the proximal phalanx of the fingers and thumb. These articulations with
Bones (instrument) finger manipulation but allowing their momentum to do the work. By moving the hand back and forth across the chest, with just enough force on the bones to keep them from falling out of the hand, a patient learner can produce a triple click. This "click-it-y" sound is the essential ingredient to playing the bones. A double-click can be produced by the same movement of the hand with the addition of a bit of pressure to the bones to suppress the third click. Once these elemental triple and double figures have been mastered, they can be combined to create complex
