Standard Ukulele String Tuning
This is the most common ukulele tuning. Soprano, concert, and tenor ukuleles are tuned in standard tuning, sometimes referred to as “C tuning.”
In the picture above, you see the notes of each string. The top string or fourth string of the ukulele is tuned to a G. The third string is tuned to a C. The second string is tuned to an E. The bottom, or first string, is tuned to an A.
Baritone Ukulele Tuning (D, G, B, E) — This tuning is used on baritone ukuleles and sometimes even on tenor ukuleles. This ukulele tuning is equivalent to the tuning of the last four strings on a guitar. Sometimes this tuning is referred to “G tuning.”
