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) combinations of rhythmic sounds. The effect is further enhanced by the use of two pairs of bones, one in each hand. A skilled practitioner can produce a wide variety of percussive sounds reminiscent of those made by a tap dancer. The Irish tradition is unique to the island. While North American players are typically two-handed, the Irish tradition finds the vast majority of bones players using only one hand, a distinction in method that has a strong impact on musical articulation. The comparison of the function of banjo rolls with that of bones within an ensemble suggests that stereotypically a
