Note: The G string in standard tuning is higher pitched than the C string (re-entrant tuning).
The most common ukulele tuning is G-C-E-A, also known as "C Tuning" or "Standard Tuning". What makes it unique is the re-entrant G string—it's tuned higher than the C string, not lower as you might expect.
This high G creates the ukulele's signature bright, cheerful sound. Some players prefer "Low-G" tuning where the G string is an octave lower, giving a fuller, more guitar-like tone.
Click 'Start Tuning' to enable your microphone. Play each string one at a time and adjust the tuning peg until the needle is centered and turns green. Start with the G string (closest to your face when holding the uke).
Standard ukulele tuning is G4-C4-E4-A4, also known as 'C Tuning'. The G string is often higher pitched than the C string (re-entrant tuning), giving the ukulele its characteristic bright, happy sound.
New strings stretch and need time to settle. Humidity and temperature changes also affect tuning. Stretch your strings gently when new, and always tune up to the note (not down) for better stability.
Yes! This online ukulele tuner uses your device's microphone to detect the pitch in real-time. Make sure you're in a quiet environment for the most accurate results.
Our tuner is optimized for standard GCEA tuning. Baritone ukuleles use DGBE tuning—you can use our Guitar Tuner (same notes as the 4 highest guitar strings) for that.
