GUITTAR, GUITARRA, a musical instrument of the stringed kind, with five double rows of strings; of which those that are bass are in the middle, except it be for the burthen, an octave lower than the fourth. — This instrument was first used in Spain, and by the Italians. In the former country it is still greatly in vogue. There are few of that nation who cannot play on the guitar; and with this instrument they serenade their mistresses at night. At Madrid, and other cities in that country, it is common to meet in the streets young men equipped with a guitar and a dark lantern, who, taking their station under the windows, sing, and accompany their voices with this instrument; and there is scarce an artificer or day-labourer in any of the cities or principal towns, who does not entertain himself with his guitar.
