What is Low G Ukulele Tuning?
Standard ukuleles are famous for their unique re-entrant tuning. In standard soprano, concert, and tenor setups, the 4th string (G4 at 392.00 Hz) is higher in pitch than the 3rd string (C4 at 261.63 Hz). This produces the characteristic light, syncopated, high-pitched chime often described as "My dog has fleas."
In contrast, Low G tuning replaces that 4th string with a thicker gauge string tuned a full octave down to G3 (196.00 Hz). This transforms the instrument into a linear tuning system: the strings now rise sequentially in pitch from lowest to highest: G3 < C4 < E4 < A4.
Why Musician Strummers and Fingerstyle Players Love Low G
Switching from High G to Low G completely expands what is musically possible on a single instrument:
Five Extra Half-Steps of Bass
With G3 as your root open note, you gain access to rich baseline counterpoint and low harmony notes that are simply unreachable on high-G ukuleles.
Full Solo Fingerpicking
Low G is the standard setup for solo artists like James Hill and Jake Shimabukuro when arranging classical, jazz, and contemporary acoustic songs.
100% Identical Chords
You don't need to learn any new fingerings! All your chord charts, scales, tabs, and songs use the identical finger patterns as standard tuning.
High G vs Low G: Side-by-Side Comparison
| Comparison Metric | Standard High G (gCEA) | Low G (GCEA) |
|---|---|---|
| Tuning Structure | Re-entrant (4th string higher than 3rd) | Linear (Lowest to highest sequentially) |
| 4th String Frequency | 392.00 Hz (G4) | 196.00 Hz (G3) |
| Ideal Playing Style | Rhythmic strumming, campfires, Hawaiian chime | Solo fingerstyle, classical, jazz, recording |
| Best Ukulele Sizes | Soprano, Concert, Tenor | Concert, Tenor (optimal body volume) |
How to Convert Your Ukulele to Low G
Converting any concert or tenor ukulele to Low G is straightforward and reversible:
- Select Your String: You can purchase a dedicated 4-string Low G set or buy an individual Low G string (e.g. Aquila Red Series unwound or D'Addario wound).
- Check the Nut Slot: Because a Low G string has a thicker diameter, test if it sits completely in the 4th string nut slot without binding. If it sits high above the first fret, gently widen the slot using a folded piece of fine sandpaper. Do not deepen the slot—only widen it!
- Wind and Tune: Thread through the bridge and peg, leave 2 to 3 winds on the post, and use our online Low G tuner tool above to bring the string up to 196.00 Hz.

Frequently Asked Questions About Low G Tuning
What is the difference between wound and unwound Low G strings?
A wound Low G string has a fine metal wire (silver-plated copper or aluminum) wrapped around a synthetic core. This gives great projection and bright sustain, but can create a subtle "scratch" sound when sliding your fingers. An unwound composite string (like Aquila Red Series) blends copper powder directly into synthetic gut, providing warmth and zero finger squeak.
Can I tune a standard High G string down to Low G?
No. Tuning a standard thin G4 string down an entire octave will cause it to lose all tension. The string will feel like a loose rubber band, flop against the frets, and fail to produce musical pitch. You must install a proper thick Low G gauge string.
How do I tune a Low G ukulele by ear if I don't have a tuner?
You can use the 5th fret method: Hold down the 5th fret of your 4th string (Low G). That fretted note is a C, which must match the open 3rd string (C4). Once String 3 is matched, tune strings 2 and 1 as normal.
