Concert Ukuleles:

Concert Ukuleles are the second smallest of the ukulele family. Concert ukuleles are usually around 24 inches in length, and usually have between 15 and 19 frets. The Concert ukulele has a slightly bigger body than the Soprano Ukulele, and so has a bigger sound, but still close to a typical ukulele tone. The Tenor Ukulele is bigger, making it sound, for some, closer to a guitar.

Concert Ukuleles are usually tuned gCEA, the same as Soprano Ukuleles and Tenor Ukuleles. Some people prefer Concert Ukulele strings with Low G ukulele strings rather than the typical ukulele High G strings (this is then written with a capital G rather than a small g; GCEA).
