The cithara or kithara (Greek: , translit. kith?ra, Latin: cithara) was an ancient Greek musical instrument in the lyre or lyra family. In modern Greek the word kithara has come to mean "guitar", a word which etymologically stems from kithara.
The kithara was a professional version of the two-stringed lyre. As opposed to the simpler lyre, which was a folk-instrument, the kithara was primarily used by professional musicians, called kitharodes. The kithara's origins are likely Anatolian. The barbiton was a bass version of the kithara popular in the eastern Aegean and ancient Anatolia.
In the Middle Ages, cythara was also used generically for stringed instruments including lyres, but also including lute-like instruments. The use of the name throughout the Middle Ages looked back to the original Greek kithara, and its abilities to sway people's emotions.
The kithara had a deep, wooden sounding box composed of two resonating tables, either flat or slightly arched, connected by ribs or sides of equal width. At the top, its strings were knotted around the crossbar or yoke (zugon) or to rings threaded over the bar, or wound around pegs. The other end of the strings was secured to a tail-piece after passing over a flat bridge, or the tail-piece and bridge were combined. Most vase paintings show kitharas with seven strings, in agreement with ancient authors, but these also mention that occasionally a skillful kitharode would use more than the conventional seven strings.
It was played with a rigid plectrum held in the right hand, with elbow outstretched and palm bent inwards, while the strings with undesired notes were damped with the straightened fingers of the left hand.
The kithara was the virtuoso's instrument, generally known as requiring a great deal of skill.
The kithara was played primarily to accompany dance , epic recitations, rhapsodies, odes, and lyric songs. It was also played solo at the receptions, banquets, national games, and trials of skill. The music from this instrument was said to be the lyre for drinking parties and is considered an invention of Terpander. Aristotle said that these string instruments were not for educational purposes but for pleasure only.
A Greek mythology story goes that she ascended the steep slopes of Mount Parnassus where she was welcomed by the Muses. She wandered through the laurel grove and came upon the cave of Apollo, where she bathed in the Castalian Spring and took Phoebus' plectrum to play skillful music. The sacred nymphs danced while she stroked the strings with much talent to bring forth sweet musical melodies from the resonant kithara.

There is evidence of citharae shaped like a lute, that is with a neck and an elongated body, even before the 12th century: the Golden Psalter of St Gall depicts King David wielding an instrument ... this instrument resembles a lute more than a cythara [lyre] ... Further evidence appears in the Stuttgart Psalter ... several images of an instrument ... in the text, next to all these miniatures, the instrument is called a cythara ...
