How To Tune A 12 String Guitar (step-by-step Guide)

Hey there, guitar wizards and wannabes! So, you've snagged yourself a glorious, shimmering 12-string guitar, huh? That's awesome! You're about to enter a whole new world of sound, a veritable symphony in your lap. But before you unleash that angelic chorus, there's a little… nuance to getting it sounding right. We're talking about tuning, my friends. And let me tell you, tuning a 12-string is a bit like wrangling a herd of particularly enthusiastic cats. It's doable, but it requires a touch of patience and a whole lot of love.
So, grab your coffee, your tea, or maybe something a little stronger if you’re feeling adventurous, and let's dive into this sonic adventure. Don't worry, it’s not as scary as it sounds. Think of it as a fun puzzle, a musical challenge that will reward you with pure, unadulterated awesomeness. You’ve got this!
The 12-String Symphony: Why It's a Little Different
First off, why is tuning a 12-string guitar a thing? It's not like your trusty six-string just needs a little tweak and you're off. Nope. A 12-string, as the name implies, has twelve strings. Mind-blowing, I know! But here’s the kicker: most of those strings come in pairs.
You’ve got your standard six tuning pegs, but each one is connected to two strings. Pretty neat, right? These pairs are usually tuned in octaves or unison. For example, the low E strings might be an E and a higher E an octave above. The A strings might be an A and a higher A. And so on. This is what gives you that big, rich, jangly sound. It’s like a built-in chorus effect, but way more authentic. Imagine if your regular guitar had a shy twin hiding behind it, always ready to chime in. That's what’s happening here.
The tricky part? Getting those pairs perfectly in tune with each other, and then with the rest of the guitar. Even a tiny difference can make your beautiful 12-string sound… well, a little like a drunken choir. And nobody wants that, do they? We’re aiming for celestial harmonies, not a bar brawl of notes.
Gather Your Tools (It’s Not Rocket Science!)
Okay, so you don’t need a degree in theoretical physics to tune this beast. But a few things will make your life a whole lot easier.
- A Reliable Tuner: This is your best friend. A clip-on tuner is great because it attaches to your headstock and picks up vibrations directly. Digital tuners are also fantastic. Even a tuning app on your phone can work in a pinch, though sometimes ambient noise can mess with them. Accuracy is key here, people!
- A Capo (Optional, but Handy): We’ll get to why this can be a secret weapon later.
- A Comfortable Chair: Trust me on this. You’ll be spending a bit of time with your guitar, so make yourself cozy.
- Patience, My Friend: This is the most important tool. Seriously, it's like the secret ingredient in grandma's cookies. Don’t rush it.
Once you’ve got your arsenal assembled, you’re ready to face the 12-string challenge. Deep breaths. You’ve got this. It’s just a few more strings than you’re used to. Think of it as a warm-up for a marathon.
The Standard Tuning Conundrum (It’s Not That Standard!)
Most 12-string guitars are tuned just like a regular 6-string, but with those octave/unison pairs. So, the standard tuning is E-A-D-G-B-E. But remember, each of those letters represents two strings.
The Low E Strings: The Foundation
Let’s start from the bottom, shall we? Your two lowest strings. These are your E strings.
You’ll have one thicker E string, which is your standard E note. Tune this first, just like you would on a 6-string. Now, the second E string is usually tuned an octave higher. So, you want it to sound like that higher E that your regular guitar would make. It’s a brighter, thinner sound.
Here’s where the fun begins: Tune the thicker E string to your desired low E. Then, tune the thinner E string up until it matches the octave. You might be tempted to tune the thinner one down, but that’s generally not how it’s done. Think of it as building up. You’re adding that sparkly layer.

Pro Tip: Play both E strings together. They should sound harmonious, with the higher one adding a shimmering quality. If they sound like they’re fighting, they’re probably not in tune with each other. It’s like trying to have a conversation with someone who’s talking over you. Annoying, right?
The A Strings: Getting Deeper (Sort Of)
Moving up, we have the A strings. Just like with the E’s, you have a thicker A and a thinner A.
The thicker A string is your standard A. Tune that up. Now, for the second A string, this is where it can vary slightly depending on your preference or the guitar itself. Sometimes, it's tuned in unison with the first A. But more often, it's tuned an octave higher, just like the E strings. This creates that lovely richness.
So, tune your thicker A string. Then, tune the thinner A string to match its octave. You’ll be listening for that sweet, full sound. If they’re clashing, it’s time for a little more fine-tuning.
Remember: Listen closely! The goal is for them to blend, not to grate on each other’s nerves. Imagine them holding hands, not throwing punches.
The D Strings: The Heart of the Matter
Next up are your D strings. Same principle, different note. Tune your thicker D string first.
Then, tune the thinner D string to its octave. This pair really contributes to the “wall of sound” effect that 12-strings are famous for. It’s like adding another layer of icing to an already delicious cake.
Don’t get discouraged! If it sounds a little off at first, just keep at it. You’re training your ear and your fingers. It’s a journey, not a race to the finish line.

The G Strings: The Sweet Spot
Now, the G strings. This is where things can get a tiny bit different for some guitars, but for standard tuning, it’s usually the same idea: octave pairs.
Tune the thicker G string. Then, tune the thinner G string to its octave. This pair is really going to sing when it’s in tune. It’s like the lead singers of your guitar choir.
A little trick: When you strum all six of your main notes (E, A, D, G, B, E), and then you strum the thinner strings of each octave pair, they should sound like they’re in conversation. The thinner ones should complement the thicker ones. If they sound dissonant, you’ve got some adjusting to do.
The B Strings: Reaching for the Highs
We’re getting closer to the top! Your B strings. Again, standard tuning usually means octave pairs here.
Tune the thicker B string. Then, tune the thinner B string up to its octave. This pair adds a beautiful shimmer to the higher register of your guitar. It’s like adding glitter to a masterpiece.
Pro Tip: Some players actually tune their thinner B strings in unison with the thicker B string. This can give a different, sometimes brighter, sound. But for beginners, sticking to the octave tuning is usually the way to go. We’ll get to the fancy stuff later.
The High E Strings: The Crowning Glory
Finally, the highest strings – your E strings! These are your standard high E strings.
Here’s the deal: These are almost always tuned in unison. That means both high E strings should be tuned to the exact same note. No octave difference here. This is the brightest, most chiming part of your guitar.

Why unison? Think about it. If you had an octave difference here, it would sound a bit too jangly and out of sorts. We want a clear, ringing high note, not a screech. So, tune both of these E strings to the same note. Make sure they’re locked in together.
This is crucial: Get these two high E strings perfectly in tune with each other. A tiny discrepancy here will be amplified like crazy. It's like a tiny crack in a dam; it can cause big problems!
Putting It All Together: The Tuning Dance
So, you’ve tuned each pair individually. Awesome! But now, we need to make sure the entire guitar is in tune. This is where the magic (and a bit of frustration) happens.
Step 1: The Master Tune
Start with your lowest string, the thick E. Tune it up to E. Then, tune its octave partner. Then move to the A’s, tune the thick A, then its octave partner, and so on, all the way up to the high E’s.Step 2: The Harmonious Check
Now, play all the strings together. Listen. Does it sound good? If not, don’t panic. Go back and check your pairs. Did you accidentally nudge one of the pegs? It happens to the best of us!Step 3: The Chordal Symphony
Play some basic open chords. C, G, D, A. Listen to how they sound. A 12-string really shines when played open, so pay attention to those open-voiced chords. If they sound muddy or out of tune, it's time to revisit your tuning.Step 4: The Octave Refinement
This is the key to a sweet-sounding 12-string. For each pair (except the high E’s), play the thick string and then the thin string. They should sound like they’re in perfect harmony. If the thin string sounds sharp or flat compared to its octave, adjust it. You might need to go back and forth a few times. It’s a delicate dance.It’s like tuning two singers who are supposed to hit the same note, but one is slightly off. You keep nudging them until their voices blend perfectly.

Step 5: The Unison Lock-In
For the high E strings, make sure they are exactly the same pitch. Play them together. If you hear any "beats" or wavering, they’re not perfectly in tune. You might need to use your tuner’s fine-tuning capabilities here.Step 6: The Stress Test (Optional but Recommended)
Once you think you’ve got it, try playing a song you know well. This will really expose any tuning issues. You’ll hear them more clearly when you’re actually trying to make music.Don't be afraid to go back to step one if needed! Sometimes, tuning one string can slightly affect the tension on the neck, which can subtly throw off another string. It's a chain reaction, like dominoes falling.
When Things Get Wobbly: Troubleshooting Tips
So, your 12-string is still sounding a bit like a herd of wild horses? Here are a few things to check:
- Old Strings: Worn-out strings are notoriously difficult to keep in tune. If your strings are old and grimy, it might be time for a fresh set. It's amazing what new strings can do for both sound and tuning stability.
- Tuning Peg Issues: Are your tuning pegs slipping? If they feel loose or don’t hold tension well, you might need them tightened or replaced. A guitar tech can help with this.
- Nut and Saddle: Sometimes, the nut (where the strings rest at the headstock) or the saddle (at the bridge) can have issues that cause tuning problems. If you notice strings binding or not moving smoothly when tuning, this could be the culprit. Again, a guitar tech is your friend.
- Neck Relief: If your neck has too much or too little "bow" (relief), it can affect tuning. This is a more advanced adjustment, so if you're not comfortable with it, leave it to the pros.
- Environment: Extreme temperature or humidity changes can wreak havoc on a guitar's tuning. Try to keep your guitar in a stable environment.
Advanced Tuning Tactics (For When You're Feeling Brave)
Once you've mastered standard tuning, you might want to experiment. Some players tune their 12-string to an open G or open D. This gives you even richer, more resonant sounds for certain styles of music.
A capo is your secret weapon here. If you’re tuning to an open G, for example, you’d tune your strings to G-D-G-B-D-G, and then use a capo on the first fret to get it back to A. It’s a bit of a mind-bender, but it unlocks a whole new sonic palette.
Another fun trick is to tune the octave strings slightly sharp or flat compared to the main string. This creates a natural chorus or vibrato effect. It's a subtle thing, but it can really add character to your playing.
The Sweet Reward
Tuning a 12-string guitar can feel like a marathon sometimes. There will be moments you want to throw it out the window (don't do that!). But when you finally get it sounding just right, when you strum that first chord and it rings out with that incredible, shimmering fullness… oh boy. It’s pure magic.
It’s that sound that makes you forget all the fiddly bits. It’s the sound of a thousand angels singing (or at least a really good folk band). So, keep at it, embrace the process, and soon you'll be a 12-string tuning maestro. Happy strumming!
