The walaycho (hualaycho, maulincho, or kalampiador) is a smaller relative, with a scale typically around 30 cm long. It has 10 strings (which may be of metal, nylon, or nylon fishing line) arranged in 5 courses of two strings each. Despite the short scale the headstock must still accommodate ten tuners, which increases the total length of the instrument by nearly a third (ca. 56 cm is typical). Usually tuned a fifth higher (sometimes a fourth higher) than the charango, strings in the 3rd (center) course may be either in unison or in octaves.
