A fingerpick is a type of plectrum used most commonly for playing bluegrass style banjo music. Fingerpicks are most commonly composed of metal or plastic. Unlike guitar picks, which are held between the thumb and finger and used one at a time, fingerpicks clip onto or wrap around the end of the fingers and thumb (generally three are used: one for the thumb, and one each for the middle and index fingers) and thus one hand can pick several strings at once. Fingerpicks generally are manufactured in varying thicknesses to accommodate different musicians' styles of playing: thin picks produce a quieter, more delicate sound; while thick picks produce a heavier sound.
