低音提琴
According to the "New Grove Dictionary of Music and Musicians", an "Electric bass guitar [is] a Guitar, usually with four heavy strings tuned E1'–A1'–D2–G2." It also defines "bass" as "Bass (iv). A contraction of Double bass or Electric bass guitar." According to some authors the proper term is "electric bass". Common names for the instrument are "bass guitar", "electric bass guitar", and "electric bass" and some authors claim that they are historically accurate. As the electric alternative to a double bass (which is not a guitar), many manufacturers such as Fender list the instrument in the electric bass category rather than the guitar category.
