Tune your ukulele with precision
Tips for accurate tuning:
- Play one string at a time, let it ring clearly
- Tune in a quiet environment for best results
- The needle should be centered (green) when in tune
- Flat (♭) means too low, sharp (♯) means too high
Standard Tuning (GCEA)
For Soprano, Concert, and Tenor ukuleles, the standard tuning is g-C-E-A.
| String | Note | Octave | Frequency | Position |
|---|---|---|---|---|
| 4 (Top) | G | G4 | 392.00 Hz | Closest to your face |
| 3 | C | C4 | 261.63 Hz | Thickest string |
| 2 | E | E4 | 329.63 Hz | - |
| 1 (Bottom) | A | A4 | 440.00 Hz | Closest to floor |
The "High G" vs. "Low G"
Most ukuleles use Re-entrant Tuning (High G). This means the top string (G) is actually higher in pitch than the next string (C), giving the instrument its characteristic cheerful sound.
- High G: Standard. The G string sounds high and jangly.
- Low G: Requires a special thick string. The G is tuned down an octave (196 Hz) for a deeper, guitar-like range.
Baritone Tuning (DGBE)
The Baritone ukulele is larger and tuned lower, exactly like the top four strings of a guitar.
| String | Note | Frequency |
|---|---|---|
| 4 (Top) | D | 146.83 Hz |
| 3 | G | 196.00 Hz |
| 2 | B | 246.94 Hz |
| 1 (Bottom) | E | 329.63 Hz |

New Strings? Read This!
Nylon ukulele strings are notorious for stretching. If you just put on fresh strings, they will go out of tune constantly for the first few days.
- The Fix: Tune it up, then gently pull on the string to stretch it manually. Retune. Repeat 5-10 times per string until it stabilizes.
Frequently Asked Questions
Why is my G string higher than my C string?
This is intentional! It's called "re-entrant" tuning. Unlike a guitar where strings go Low-to-High, the ukulele's G string is pitched high to facilitate close-voiced chords and rapid strumming patterns.
Can I use a guitar tuner for my ukulele?
Yes, but be careful. A standard guitar tuner might expect the low E-A-D strings. Use "Chromatic" mode on your tuner (or this website) to detect the specific C and G notes of a ukulele.
How often should I tune?
Nylon strings are temperature sensitive. Tune every time you pick up the instrument, and check tuning every 15 minutes if you are playing vigorously or if the room temperature changes.
