A guitar is a stringed musical instrument, favored in southern Europe during the Renaissance. Its body was flat-backed, narrowed slightly at the waist, with a fretted neck longer in proportion than the citole or the gittern. The Renaissance guitar was similar in shape (though smaller) to the modern classical guitar; the illustration is taken from Morlaye’s Premier Livre de Chansons en tabulature de guiterne, 1552 [Grove 10:554]. Though a period instrument, the guitar doesn’t seem to have been used in period armory; its Society default orientation is affronty, with strings facing the viewer, and with neck to chief. For related charges, see lute.
