The electric bass guitar also called electric bass,or simply bass; pronounced /ˈbeɪs/, as in "base") is a stringed instrument played primarily with the fingers or thumb either by plucking, slapping, popping, tapping, or thumping,or by using a plectrum.

The bass guitar is similar in appearance and construction to an electric guitar, but with a larger body, a longer neck and scale length, with a four, some with five, or six strings tuned to the same pitches as those of the double bass, which correspond to pitches one octave lower than those of the four lower strings of a guitar (E, A, D, and G).The bass guitar is a transposing instrument, as it is notated in bass clef an octave higher than it sounds (as is the double bass) in order to avoid the excessive use of ledger lines. Like the electric guitar, the electric bass guitar is plugged into an amplifier and speaker for live performances.
