The finely placed nylon strings around the guitar sound melodious with any music, from jazz to classical. The modern kinds of classical guitars were pioneered by Antonio Torres Jurado. There is a roster of classical guitars classified distinctively according to their functions and usages. These include the small requinto, the bigger guitarron, and others. The requinto is a well-famed type, found mostly within the Latin-American nations just as one associated part of the guitar family.
