by “What is low-G tuning?” “Why does my ukulele sound so jangly?” “Should I switch to low-G?” If you’ve been Googling any of these, you are not alone. We’ve all been there, staring at our uke and wondering what that little g actually means. Good news: it’s a small change with a big effect on your sound and by the end of this guide you’ll know exactly which one suits the way you play.
First things first: what standard tuning really is
Your ukulele almost certainly came tuned to standard gCEA. Those four letters are the open notes of your strings, from the 4th string (closest to your face when holding your ukulele in the playing position) down to the 1st string (closest to the floor).
Here’s the part that surprises most beginners. In standard tuning that top g is reentrant (= the strings don’t run simply low to high, one of them jumps back up). The 4th string g is tuned HIGHER in pitch than the 3rd string C. It actually sits up near your E and A strings, not below them.
Think of it like a singing group where you’d expect the order to go low to high, but one voice unexpectedly pops up into the higher range. That little jump is the secret behind the classic ukulele sound.

High-G (reentrant): the classic ukulele sound
High-G is what most ukuleles come with and it’s the sound in your head when you picture a ukulele. Bright, sparkly and sweet.
That famous “my dog has fleas” jingle? Strum the open strings and you’ll hear it. The reason it sounds so jangly is exactly that reentrant g. Because the highest-pitched note is hiding in the middle of your chords instead of at the bottom, your strums ring out in a bright sparkly cluster rather than a tidy low-to-high run.
It’s perfect for strumming, singalongs and campfire songs. If you’re a beginner who mostly wants to strum and sing, high-G is your friend. Stick with it.
Low-G (linear): more range and a fuller bottom end
Low-G keeps the C, E and A strings exactly the same. The only thing that changes is the 4th string. You swap that thin high-g string for a thicker string tuned a full octave lower (= the same note name, just much deeper in pitch).
Now your four strings run in a tidy line from low to high, just like the top four strings of a guitar, only pitched a little higher. This is called linear tuning, because the pitch climbs in order with no jump.
What does that get you? A whole extra chunk of low range underneath your playing. Melodies sound smoother, fingerpicking sounds richer and your solos suddenly have a fuller, rounder bottom end. The trade-off is that you lose some of that signature jangle. It leans a touch more guitar-like.
In my opinion the difference really shines the moment you start picking single notes. I keep one ukulele strung with low-G just for fingerpicking and it sounds like a totally different instrument, in the best way.
High-G vs low-G at a glance
| High-G (reentrant) | Low-G (linear) | |
|---|---|---|
| 4th string pitch | Higher than the C string | One octave lower |
| Sound | Bright, jangly, sweet | Fuller, rounder, smoother |
| Range | Compact | Wider (extra low notes) |
| Best for | Strumming, singalongs | Fingerpicking, melody, solos |
| Ships standard? | Yes, on most ukes | No, you switch to it |
Remember, only the 4th string is ever in question. The C, E and A strings stay put no matter which camp you join.
Does it change my chords?
Good question and the short answer is no. Your chord shapes stay exactly the same in both tunings. An open C is still an open C.
The same finger goes on the same fret either way. Low-G just adds a deeper note to the bottom of some chords. So you can switch over without relearning a single shape. Trust me, that’s a relief (it was for me when I learned about this).
Who should pick which?
If you’re a beginner who mostly strums and sings, stick with the high-G your ukulele came with. It’s the traditional sound and you’ve got nothing to fix.
If you love fingerpicking, want to play melodies and solos or just crave more low-end range, give low-G a try. Players who came over from guitar often feel right at home with it too.
Honestly, you don’t have to choose forever. I play high-G for everyday strumming and keep a separate low-G uke for quieter fingerpicking sessions. Plenty of players end up with one of each.
How to switch to low-G
The good news is this is cheap and easy. You don’t need a new ukulele.
Buy a single low-G string or a full low-G string set. Aquila and several other brands make them and you can read more in my guide to the best ukulele strings. Pull off your old 4th string, fit the new low-G in its place and tune it up.
One small heads-up. Some low-G strings are wound (= wrapped in a thin metal coil, like a guitar string) and a touch thicker than the slot they sit in at the nut (= the little grooved strip at the top of the neck). If your new string feels pinched or won’t seat properly, a luthier can file that one slot a hair wider in a couple of minutes. A lighter unwound low-G string usually drops right in with no fuss at all.
Either way, give it a fresh tune-up afterward and let the string settle for a day. New strings always drift a little while they stretch in.
