Standard soprano, concert and tenor ukuleles use g C E A — note the high re-entrant G, which sits above the C rather than below it. That bright top string is what gives the uke its signature sound.
G4C4E4A4
Quick way to remember the strings: Good Cooks Eat A-lot.
| Tuning | Notes |
|---|---|
| Low-G | G3 C E A — fuller, guitar-like low end |
| D-tuning | A D F# B — a tone higher, older/traditional sound |
| Baritone | D G B E — like a guitar's top four strings |
Switch the instrument selector above to chromatic mode to tune to any of these notes by ear.
