Guitare

Guitare _Designed by EDPTechEdStudent ( http://www.thingiverse.com/thing:260383 ) _Guitar, plucked stringed musical instrument that probably originated in Spain early in the 16th century, deriving from the guitarra latina, a late-medieval instrument with a waisted body and four strings. The early guitar was narrower and deeper than the modern guitar, with a less pronounced waist. It was closely related to the vihuela, the guitar-shaped instrument played in Spain in place of the lute. _The guitar originally had four courses of strings, three double, the top course single, that ran from a violin-like pegbox to a tension bridge glued to the soundboard, or belly; the bridge thus sustained the direct pull of the strings.rom the 16th to the 19th century several changes occurred in the instrument. A fifth course of strings was added before 1600; by the late 18th century a sixth course was added. Before 1800 the double courses were replaced by single strings tuned E–A–d–g–b–e′, still the standard tuning. _In the 20th century, Andrés Segovia gave the guitar further prominence as a concert instrument, and composers such as Heitor Villa-Lobos and Manuel de Falla wrote serious works for it; others (e.g., Pierre Boulez) scored for the guitar in chamber ensembles.
