The ronroco is an instrument created by one of the members of Los Kjarkas, it is a mix between the charango and the guitar. Its sound is lower than that of a charango but higher than that of a guitar. The tuning is the same as that of a charango with the first and fourth strings in one low octave. For the fifth strings one changes to Sol to one low octave. The hualaycho is a more local instrument and can be tuned in many ways, the most comon are: It can be compared to a charango with a capoteaste in the third fret, in other words, tuned in Sol. The most comon tune is in La, like using the capoteaste in the fifth fret. The sound of the hualaycho is beeper than that of the charango, usually it is used for the called Klampeo which is to make melodies scratching the strings.
