Reentrant tuning

[3] The Andean charango, a small 5-course, 10-string guitar frequently made from an armadillo shell, is most usually tuned in re-entrant fashion, with re-entry before and after the octave strung third course.

These tunings may also be used on related instruments, such as ten string electric and jazz guitars.

The Venezuelan cuatro is a member of the guitar family, smaller in size and with four nylon strings.

The traditional "Camburpinton" tuning is re-entrant (A3–D4–F♯4–B3), but with the re-entry between the second and first strings, rather than between third and fourth as in the ukulele.

The ten-string, five-course Puerto Rican cuatro is not tuned re-entrantly, but in straight fourths.
