Jarana

A Jarana is a guitar-shaped fretted stringed instrument, from the southern region of the state of Veracruz, Mexico. Typically strung with 8 strings in 5 courses, usually arranged in two single outer strings with three courses between. The strings are usually nylon, although they were gut in the past. The body is somewhat narrower in proportion to a guitar; this is due to its direct lineage from the Spanish baroque guitar of the sixteenth century. Sometimes mistaken for a ukulele, the jarana jarocha comes in at least four sizes, the smallest being the 'mosquito', about the size of a soprano ukulele; the 'primera', about the size of a concert ukulele; the 'segunda', in length between a tenor and a baritone ukulele; and the 'tercera', which is somewhat longer than the baritone ukulele.
