How to tune to Ukulele
- 1Tap Start Tuning. Allow microphone access. Nothing is recorded or uploaded, everything runs in your browser.
- 2Pluck one string at a time. Start with the C string, it's the easiest to identify. The tuner auto-detects which string you're playing.
- 3Adjust until the needle centers. Tighten the tuning peg if the needle reads flat, loosen if it reads sharp.
- 4Expect to re-tune a few times. New nylon strings stretch a lot in the first sessions, so check all four strings again after playing for a few minutes.
What is Ukulele tuning
Standard ukulele tuning is GCEA, also called C tuning. From the string closest to your face to the one closest to the floor: G4, C4, E4, A4. This works for soprano, concert, and most tenor ukuleles. Unlike a guitar, standard ukulele tuning is re-entrant, the G string is tuned an octave higher than you'd expect, so pitch runs high-low-low-high across the four strings instead of climbing steadily from low to high. That re-entrant G is what gives the ukulele its bright, jangly, immediately recognizable sound.
Many tenor players prefer swapping to a low G, dropping that string a full octave for a fuller low end that suits fingerstyle arrangements. Baritone ukuleles use a different tuning entirely, DGBE, the same as the top four strings of a guitar, rather than GCEA.
Nylon strings stretch considerably when new, so expect to re-tune several times during the first few sessions with a fresh set. Once broken in, a quick check at the start of each playing session is usually enough to keep a ukulele sounding right, whether you're playing folk, pop, or the Hawaiian and island styles the instrument is best known for.
Frequently asked
What is standard ukulele tuning?
Standard ukulele tuning is GCEA, also called C tuning. From the string closest to your face to the one closest to the floor: G4, C4, E4, A4. This works for soprano, concert, and most tenor ukuleles.
Why is the G string higher than the C string?
Standard ukulele tuning is re-entrant, the G string is tuned an octave higher than you'd expect. Instead of running low to high in pitch like a guitar, the strings go high-low-low-high. This gives the ukulele its characteristic bright, jangly sound.
Can I tune to a low G instead?
Yes, many tenor players prefer low G tuning, which drops the G string an octave down. It gives the ukulele a fuller low end and works well for fingerstyle. Switch to Chromatic mode to tune it by ear against a guitar's low E reading, or once the other three strings are set.
Baritone ukulele uses a different tuning, right?
Correct. Baritone ukuleles tune to DGBE, the same as the top four strings of a guitar, not GCEA. This tuner is set up for standard soprano, concert, and tenor ukuleles. Baritone players can use the standard guitar tuner and target D3, G3, B3, E4.
How often should I tune my ukulele?
More often than you'd think, especially with new strings. Nylon stretches a lot for the first week or two, expect to re-tune several times per session. After break-in, a quick tune-up at the start of each playing session keeps you in good shape.
