Ukulele tuning: G C E A

Soprano, concert and tenor ukuleles are tuned G4 C4 E4 A4, from the string nearest your face to the one nearest the floor. The G is tuned higher than the C (re-entrant tuning), which gives the ukulele its bright, close-voiced strum. The phrase "My Dog Has Fleas" sings those four notes.

Low G tuning drops the fourth string an octave to G3 for a fuller, guitar-like bass; tenor players often use it for fingerstyle. Baritone ukuleles are tuned D G B E, the same as the top four strings of a guitar.

Nylon strings stretch for days after you fit them, so a new ukulele drifts flat quickly. Tune, play for a few minutes, and tune again. Once it holds, try strumming along with a song you made in the AI song generator.
