How to Tune a Ukulele Online
The standard ukulele tuning is gCEA (high G, then C E A). Soprano and concert ukes use this 'reentrant' tuning where the G is actually higher than the C and E. Tenor ukes often use a low-G variation (GCEA), giving a deeper sound and more melodic range. Baritone ukes are tuned DGBE: the same as the top four strings of a guitar, an octave higher than the guitar's actual pitches.
