The classical guitar—also known as the nylon-string or Spanish guitar—has a rich history dating back to the late 19th century in Spain. It evolved from earlier instruments like the vihuela and gittern. Notable composers who have written for the classical guitar include Fernando Sor, Mauro Giuliani, and Francisco Tárrega. Curious facts about the classical guitar include its use of gut or nylon strings, the different playing positions and techniques, and the development of the modern classical guitar by luthier Antonio Torres Jurado.
