The classical guitar or Spanish guitar is a musical instrument of the plucked string family, consisting of a soundboard, which usually has a hole in the center of the top, a neck on which the fingerboard is glued and six strings.
The origin of the classical guitar is very old and has European roots. There are several theories about the birth of this wooden instrument, although it is known that it evolved mainly from the zither, the lute and the vihuela. The classical guitar or Spanish guitar has suffered variations for centuries until the 19th century when Antonio de Torres established the bases and canonical measures of what today would be the modern classical guitar.
This instrument is made almost entirely of wood and among the most used varieties are Indian Rosewood, Spruce, Ebony and Honduras Cedar. In the past, the strings were made with animal gut, which fell into disuse and today it is composed of six nylon strings, three of which are covered with a metal braiding.
