Boys and girls, we’re back with Tony Iommi, and this time we’re looking at something that’s become his signature move: the root-six pentatonic climb. This is the technique that shows up in “Paranoid,” in “Sweet Leaf,” in so many Black Sabbath songs. Once you learn this, you’ll hear it everywhere in heavy metal.
What’s special about the root-six pentatonic? It’s built on the 5th string instead of the 6th string. That changes everything about the feel and the fingering. And when Tony climbs that scale with his chromatic pass notes, it creates this dark, menacing sound that’s instantly recognizable.
Building The Scale From The 5th String
The root-six pentatonic minor scale starts at the 5th fret on the 5th string. That’s your root note. From there, the fingering pattern is simple: first finger on the 5th fret, third finger on the 7th fret. That’s it. 1-3, 1-3, 1-3 as you move across the strings. No fancy finger stretches. No complicated shapes. Just a clean, repeating pattern.
Why is this so powerful? Because it’s the same pattern on every string. Once you learn it in one position, you can move it anywhere on the neck. That’s portability. That’s versatility. A young player can grab this shape and use it to solo anywhere without having to think too hard about what they’re doing.
The Chromatic Pass Note That Makes It Tony
Here’s what separates Tony Iommi from every other guitarist using the pentatonic scale: that chromatic pass note between 4 and 5. The augmented 4th, the flatted 5th, the devil’s note—whatever you want to call it. That’s his signature.
When you’re climbing the scale, you hit the regular note, then you sneak in that chromatic passing note just before you move to the next string. It’s subtle, but it changes everything. It adds tension. It creates dissonance. And dissonance is what makes metal feel heavy.
The Descending Run and Position Changes
Now let’s talk about the descending riff. You’re starting at the 11th fret on the 4th string. From there, you’re moving downward across the strings with those chromatic pass notes built in. The riff flows from one string to the next, getting lower and lower, darker and darker.
Here’s something important: Tony would play this same concept in different positions. Once you’ve got it down at the 11th fret position, try moving it down a whole step. Then move it down another position. The pattern stays the same. The fingers move to new frets. But the sound and the shape remain consistent. That’s mastery.
The Story Behind Tony’s Hands
Let me tell you something that might surprise you. Tony Iommi lost his fingertips in a factory accident when he was young. Two fingers on his right hand. So he had to adapt. He used his right hand to fret the strings instead of his left. He’s a left-handed guitar player using right-handed technique. Most people would’ve quit. Tony became one of the greatest guitarists who ever lived.
Why am I telling you this? Because it shows you that technique doesn’t matter as much as determination and creativity. Tony couldn’t play the same way as other players. So he found his own way. That’s where his genius comes from. That’s where all great guitar playing comes from.
Add The Distortion and Make It Sing
Here’s the final piece of the puzzle: distortion. These licks work clean, sure. But Tony’s tone comes from a heavily distorted amp. The riff we’ve been talking about? Take it and run it through a fuzzy, overdriven tone, and suddenly it sounds like the earth is opening up beneath you.
If you want to go deeper with this stuff, I’d recommend picking up Tony’s autobiography. He talks about his approach to music, his philosophy, and his journey. It’s honest and inspiring. And it’ll give you perspective on what it means to be a serious guitarist.

You’ve Got The Tools
That’s two parts of Tony Iommi’s playbook. Part 1 covers the chromatic pass notes. Part 2 here gives you the root-six pentatonic climb. You’ve got the positions and the patterns. Now it’s up to you. Get that distortion cranked up, and start making some heavy music. Tony shows us that limitations can become strengths. Your job is to find your own voice within these tools.
