The cythara is a wide group of stringed instruments of medieval and Renaissance Europe, including not only the lyre and harp but also necked, string instruments. In fact, unless a medieval document gives an indication that it meant a necked instrument, then it likely was referring to a lyre. It was also spelled cithara or kithara and was Latin for the Greek lyre. However, lacking names for some stringed instruments from the medieval period, these have been referred to as fiddles and citharas/cytharas, both by medieval people and by modern researchers. The instruments are important as being ancestors to or influential in the development of a wide variety of European instruments, including fiddles, vielles, violas, citoles and guitars. Although not proven to be completely separate from the line of lute-family instruments that dominated Europe (lute, oud, gittern, mandore), arguments have been made that they represent a European-based tradition of instrument building, which was for a time separate from the lute-family instruments.
In the 9th century, one of the instruments that cythara was actively used to name was a large plucked or strummed instrument; pictures show it being played with a plectrum. Pictures of the instrument illustrated in the Stuttgart Psalter all have the word "cythara" near the instrument in the text. The players hold the instrument in a distinct manner similar to the way that citole players were shown to hold their instruments, resting the instrument on the playing arm, and bringing their forearm and wrist to the strings from underneath the body of the instrument. In contrast, players of lute family instruments, such as the gittern, mandore, or lute did not hold the instrument this way. Instead of keeping their arms below the instrument, they allowed their arm and wrist to move parallel to the soundboard, as a guitar player does today.
