Electric Bass Guitar
The bass guitar is a stringed instrument played primarily with the fingers or thumb, by plucking, slapping, popping, strumming, tapping, thumping, or picking with a plectrum, often known as a pick. It is similar in appearance to an electric guitar, but with a longer neck and scale length, and traditionally with four strings.
Since the 1960s, the bass guitar has largely replaced the double bass in popular music as the bass instrument in the rhythm section. Bass masters such as Jaco Pastorius, Geddy Lee, Marcus Miller and John Paul Jones pushed the envelope on what could be accomplished on just four strings. Bass players are the anchor between the kick drum and musical ensemble. They dictate the bottom end feel, tempo and rhythmic outline within a song structure.
