Bajo sexto

Bajo sexto (Spanish: "six bass") is a Mexican string instrument with 12 strings in 6 double courses. A closely related instrument is the bajo quinto (Spanish: "five bass") which has 10 strings in 5 double courses.

In playing, the left hand holds the strings against frets on a fingerboard, while the right hand plucks the strings. When played in older styles of music where the instrument assumes the role of a bass, the strings are usually plucked with the fingers. In modern chordal and melodic styles, a pick is frequently used.
