4-string guitar
A 4-string guitar, often called a bass guitar, is a stringed instrument primarily used to provide rhythm and low-pitched notes in music. It has four thick strings, tuned typically to E, A, D, and G, which produce deeper sounds than a regular six-string guitar. The instrument is played by plucking or picking the strings, and it often functions as the foundation of harmony in a band. Despite having fewer strings, it requires skill to produce precise notes and rhythms, making it a vital component in various musical styles such as jazz, rock, and funk.
