Ball-end nylon strings work great for the wee ones, no bridge conversion needed....

Many children's music classes suggest the 4 string Baritone Ukulele for the young students that show an interest on guitar playing. The reason behind this suggestion is:
1: Baritone Ukuleles are tuned like the first four strings of the guitar : EBGD.
2:The strings for Baritone Ukes are nylon-straings NOT STEEL strings.
3:A small child's hands will adapt quite well to the much smaller fret board of the Ukulele.
4:Chords used on a guitar are the same as those used in the Baritone Uke except that
since the Uke only have four strings (instead of six on the guitar) most of the chord can
be played with only two fingers.
5:When the child "grows" into a guitar he/she already knows the fret-board for the first 4 strings as well as most of the chords formation.
6: A solid-top Bariton Uke can be purchase new for under $100. (www.hobglobin.com).
