How do you rank Paul McCartney as a bassist? Quite simply, you don't. Having been exposed to the swing of big bands, the blues, and early rock and roll as a kid, he absorbed it all and wove something completely new. People talk about those melodic bass lines as though they were completely normal—they weren't. Those lines not only completely transformed good songs into great songs with the Beatles, but they transformed music as we know it today. What do you consider musical chops or being technical? His phrasing, attack, and ability to weave unassuming lines that actually define songs is unparalleled. The idea of the bass being the heartbeat of a song, the pulse, comes from his ingenuity and consistent ability to evolve. His influence is so far reaching that it is nearly impossible not to find some thread of him in music today. For all the successes he has had in his career, people overlook the incredible versatility and beauty of his bass lines.
