You want to sound like you know what you’re doing on the guitar? Here’s a trick: you only need one string.
I’m serious. This riff uses the high E string, a handful of pentatonic scale notes, and an open string drone. It sounds way more impressive than it has any right to, and you can get it going in minutes.
The Drone String Concept
Here’s the idea. You play the open high E string as a drone — a note that keeps ringing while you add other notes on top of it. E is the 5th note in the key of A minor, which makes it a perfect, neutral-sounding harmony. That open string becomes your home base, and everything else dances around it.
This technique has been used in rock music forever. It’s one of those things that sounds complicated when you hear it but is surprisingly simple once you see how it works.
The Notes You Need
Everything happens on the 1st string (high E). These are your notes:
Open string = E (your drone note). 3rd fret = G. 5th fret = A. 7th fret = B (a bonus diatonic note that adds extra flavor). 8th fret = C. 10th fret = D. 12th fret = E again (one octave up).
That’s the A minor pentatonic scale laid out on a single string, plus one extra note (the B at the 7th fret). Colin calls it “hexatonic” — a six-note scale. You don’t need to remember that word. Just remember the fret numbers.

How to Play It
The basic pattern is: double pick the open E string (down-up), then single pick a fretted note. Back to the open string, double pick again, then a different fretted note.
So it goes in groups of three: open-open-fret, open-open-fret, open-open-fret. The open string gets two strokes (down-up), the fretted note gets one.
Start with just two notes. Open E and the 5th fret (A). Down-up on the open string, down on the 5th fret. Repeat. Even that simple combination sounds like a real riff.
Then start mixing in the other notes. Open E to the 3rd fret (G). Open E to the 8th fret (C). Walk up the scale. Walk back down. Jump around. Colin puts it well — these notes are your crayon box. Now draw something.
A Killer Combination
One pattern that sounds especially good: 5th fret, 8th fret, 5th fret, 8th fret, 7th fret. That’s A, C, A, C, B. With the open E drone between each note, it creates this hypnotic, rolling sound.
You can play this slow and it sounds moody and atmospheric. Speed it up and it sounds aggressive and powerful. Same notes, different attitude.
The Picking Is Everything
The secret to making this sound good — and eventually fast — is consistent down-up picking (also called alternate picking). Every stroke alternates: down, up, down, up. No exceptions.
Start slow. Really slow. Make sure every note is clean and even. Speed comes on its own as your muscle memory develops. If you try to play fast before you’ve got the motion smooth, you’ll just sound sloppy.
This is great practice for your overall picking technique too. The skills transfer directly into everything else you play.
Fingering Options
You can do this entire riff with just your first finger sliding up and down the string. That’s the simplest approach and it works fine, especially at slower speeds.
For more speed, assign one finger per fret: 1st finger for the 3rd fret, 2nd finger for the 5th, 3rd finger for the 7th, 4th finger for the 8th. This keeps your hand in position and eliminates the slide time between notes.
Why This Works So Well for Beginners
You’re only dealing with one string. No chord shapes to memorize. No worrying about which string comes next. You’re just choosing notes and picking them. All your brain power goes into timing and creativity instead of finger gymnastics.
And it sounds like real music right away. That’s the best part. You can show this to someone who’s never touched a guitar and they’ll be making cool sounds within their first practice session.
Once you’ve got this down, you’ve got a foundation for lead guitar playing. The A minor pentatonic scale is the backbone of blues, rock, and metal soloing. You’re already playing it — just on one string.
