fretboard. On bass guitars, this is commonly done with the thumb, while on double bass, the edge of the hand or index finger may be used.

On bass guitar, the two techniques are commonly used together in alternation, though either may be used separately.

, producing a "toney" or buzzing sound that is normally avoided in plucked/fingered bass.

In the slap technique, the bassist replaces the usual plucking motion of the index and middle fingers with "slaps" and "pops". In the slap, the bassist uses the thumb to strike the strings (usually the lower E and A strings) near the base of the bass's neck. In the pop, the bassist will use the index or middle finger of the plucking hand to snap the strings (usually the higher D and G strings) away from the
body of the bass, causing them to bounce off the fretboard; this produces a prominent buzzing tone with a sharp attack and more high-frequency vibrations than present in plucked bass.
The bassist can play many notes quickly by rotating the forearm, alternately slapping and popping: during the pop, the hand moves away from the fretboard, "winding up" or getting in position for the next slap. The slap and pop techniques are commonly used with
pull-offs and
hammer-ons with the fretting (usually left) hand, to further increase the rate at which notes may be played.
