Editor's note: Every singer learns to follow the bass instead of the drums. So many classic songs open with a great bass intro. And that delicious vibration you feel in your sternum at a jam-packed super-loud concert? That's the bass. So in honor of the instrument that's the backbone of rock 'n roll, take a deep dive into our Bass Guitar collection, cue up Steve Wonder's "I Wish" and find a wallpaper.
