The baritone ukulele is the largest size instrument in the ukulele family. Unlike the standard G-C-E-A re-entrant tuning of the soprano, concert and tenor ukuleles, the baritone ukulele is tuned 2 1/2 steps lower in linear tuning (going from low to high in pitch) to D-G-B-E. It is a popular choice for guitarists looking to learn ukulele as it is tuned like the bottom four strings on a guitar.
