"Guitar" is a large class of classical stringed organs; as early as the eighth and ninth centuries, there were Arabic and Latin guitars, the earliest guitar music from the thirteenth century Castilian King Alfonso X began to germinate. By the fifteenth century, the system of lutes, another subordinate group of lutes, began to rise, gradually eliminating the original Arabic guitar and evolving the Latin guitar into the bivela. In sixteenth Century, Bi Wei La Qin used fingers to directly touch strings, playing in the Royal aristocracy. The most popular period in Spain was 1535-1578 years. The lute also laid the foundation for classical music in the sixteenth century, and still holds a place in the subordinate categories of the harp.
