Plucking is done mainly by the right hand with four plectra (picks) attached to the fingers.
Cristofori enhanced the difference in plucking points by placing the plectra on opposite sides of the jack in the two choirs, as seen in the detail figure below.
Modern harpsichords frequently employ plectra made with plastic, specifically the plastic known as acetal.
Thin items such as small coins, bread clips or broken compact discs and credit cards can be used as substitute plectra.
The plectra used are made from special ivory so that plucking can be done easily.
Feather quills were likely the first standardized plectra and became widely used until the late 19th century.
It is possible that the standard harpsichord mechanism, with jacks holding plectra mounted on retractable tongues, may only gradually have won out over alternatives.
