The Baritone sized ukulele is the largest of the four main sizes. The scale length is generally around three inches longer than that of a Tenor and subsequently features the widest nut width of the four main ukulele sizes. A key characteristic of the Baritone is its similarity to the classical guitar in terms of pitch. Typically it is tuned (low to high) D, G, B, E which is in unison with the highest four strings on the guitar. This makes for an easy transition for players who have some experience with the guitar.  

Tonally the Baritone size is rich in low end, warm and full sounding with considerable volume. Baritone Ukuleles can also be strung with  (high) G, C, E, A and (high) D, G, B, E sets which makes them wonderfully versatile.
