Paul McCartney was inspired to play the bass guitar after realizing that the instrument could fill a unique role in a band, providing both rhythm and melody. He initially played guitar but switched to bass when he joined The Beatles, filling the vacancy left by their original bassist. Influenced by the sound of rock 'n' roll and the desire to create a fuller musical experience, McCartney embraced the bass as a means to express his creativity and songwriting. His innovative approach to the instrument helped redefine its role in popular music.
