Which Led Zeppelin Guitar Riff Was Written by John Paul Jones?

Even if you don't guess the answer, don't forget to wish JPJ a "Happy Birthday."

Bass, keyboards, harp, double bass, mandolin, guitar, lap steel, continuum, sitar, keytar, banjo, saxophone, flute, viola, cello, violin — it might be quicker to list the instruments John Paul Jones doesn't play.

The Led Zeppelin bassist — who celebrated his 69th birthday this January 3rd — is credited with writing the main guitar riff to "Black Dog," saying he wanted to write a song with complex rhythm changes that people couldn't "groove" or dance to.

Think about trying to dance to "Black Dog" for a second.

Mission accomplished, JPJ.

In an interview with Cameron Crowe, Jones explained: "I wanted to try an electric blues with a rolling bass part. But it couldn't be too simple. I wanted it to turn back on itself. I showed it to the guys, and we fell into it. We struggled with the turn-around, until [John] Bonham figured out that you just four-time as if there's no turn-around. That was the secret."

Listen to what he means here.
