Theeka-tantrī vīṇā was a medievaltube-zitherveena in India, with a single string and one or more gourd resonators. The instrument became prominent in Indian music in about the 10th century C.E. as instruments of court music. Alongside thealapini vina andkinnari vina it replaced theharp-style veenas and lute-style veenas in sculpture. It was possibly a forerunner of therudra vina. It shares its name with the modern single-string drone lute, theektara.
The instrument is very closely related to the one-stringed alapini vina, an instrument which started out a stick zither but became a tube zither like the eka-tantri vina.
Although the tube zithers and stick zithers are very similar, it is possible that they have different origins. Early paintings of stick zithers in India date back at least to the 5th century C.E. The earliest currently known stick zither is in the Caves of Ajanta at the end of the 5th century.[1] After a period of assuming that tube zithers spread from India to Southeast Asia, modern scholars have been trying to decide if the tube zithers might have originated in Southeast Asia and spread to India. Whatever the origins, Indian influence on musical culture in Southeast Asia is recorded in the archaeological remains of past civilizations.[2][3][4]
Parts of the vinas from Sarnga Deva's Ratnakara:[5][6]
Instruments in paintings and sculpture are not generally labeled, and researchers have had to apply the nameeka-tantrī vīṇā (one-string vina) to different instruments. Iconography can't show whether the rods or bodies are hollow, and researchers have had to look for clues in literature.
Instruments in surviving images that are labeledeka-tantrī vīṇā are generally tube zithers with wide tubes and a gourd attached to the top, the gourd held over the musician's shoulder and the other end past their hip, with a single string and no frets. Musician's are shown sliding the straightened fingers of their upper hand on the string, or holding a stick to slide on the string, and plucking with their lower hand.[8]
The instruments are fretless, the depictions showing a single string. The later instruments labeledkinnari vina we're fretted and show traits of both the ekatantri vina and the alapini vina, with gourds that are pressed into the chest and also rise above the shoulder.[8]
In medieval artwork, a second lower gourd has been seen on both stick zithers and tube zithers. Artwork for the eka-tantri vina commonly shows a second carved resonator or gourd resonator near the instrument's lower end.
While the eka-tantri vina had only one string (the meaning of its name), it may have been modified to add additional strings and frets, moving toward the development of the rudra veena. The manner of holding the instrument is similar too. The kinnari veena with its multiple strings and frets also may also be related in the development of the rudra veena, although this instrument was held vertically in artwork, different from the manner the rudra veena was held.
Based on definitions from Indian literature, the unifying criterion is that both have a single string and a gourd resonator. The literature includes theNāṭyaśāstra (written sometime between 2nd century B.C.E. - 3rd century C.E.) byBharata Muni and theSangita Ratnakara (written 1210 - 1247 AD) byŚārṅgadeva.[3]
In the 13th century, the Sangita Ratnakara placed vinas into three categories: fretless (into which theeka-tanktri vina was placed),harps, and fretted vinas (which included thealapini vina and thekinnari vina). Frets were possibly introduced as a reaction to the invention of the 12-string scale, ca. 700-800. In 1400, the frets on thekinnari vina were attributed to Matanga (800 A.D.) the author of Brhad-desi.[7]
For theeka-tantri vina Śārṅgadeva described an instrument made ofKhadirah wood, less than a yard long (alternative translation says 3 arm lengths long), with a dandam "a stetched palm" (about 5-8 inches) in circumference, and 1.5 inches narrower on the bottom where ayali might be carved.[5]
In comparison, thealapini vina Śārṅgadeva described was an instrument 36 inches long, thered sandalwood orKhadirah wood or bamboo rod 2 inches in circumference. The cup (tumba) was made from coconut, and its string was reportedly made of silk, producing a delicate sound.[5]
Researchers Piyal Bhattacharya and Shreetama Chowdhury described theeka-tantrī vīṇā as being a larger instrument, with a "bigger tube" and bigger gourd, compared to theālāpiṇī vīṇā, which they described as a stick zither. The researchers looked at where the instrument's gourd was placed while playing; they indicated instruments with the gourd over the shoulder wereeka-tantrī vīṇās and those pressed against the chest wereālāpiṇī vīṇās.[3]
Patrick Kersale applied the labelekatantri to a 10th century tube zither from thePala Empire, a long instrument with a squared base and raised bridge-like piece (that lengthened the time the string would sound).[9] Like on the modernpinaka vina a stick was slid on the string to determine the notes.[9] With the kse diev, the gourd is pressed with different pressures into the player's, and the ring finger of the right hand plucks, while the left hand applies pressure on the string at the players chest.[10] The purpose of the bridge may also have been to create a "buzzing" quality to the note (known inIndian classical music asjivari.[2]
The writers for the vīnā entry in the New Grove Dictionary of Musical Instruments called theālāpiṇī vīṇā a stick zither, in which the stick might be a bamboo or wooden tube. They focused on how the vinas were played. The gourd on theālāpiṇī vīṇā was cut to form a cup or bowl, the opening of which could be placed against the musician's body while playing, creating a "closed resonance chamber". On theeka-tantrī vīṇā and laterKinarri vina the gourd (bottom intact) used for the resonance chamber rested over the musician's shoulder. These latter two might have a second or third gourd added further down, creating the modernkinarri vina andrudra veena[2]
In his bookBharatiya Sangeet Vadya,Lalmani Misra used Śārṅgadeva's work to describe theEka-tantri. The body of the instrument, was 3 arm-lengths long and a hand's breadth wide, hollowed out to form a tube, with a bore of 1.5 forefinger widths. A borehole (perpendicular to the instrument's bore) allows the resonating sound in the tube to pass into each gourd resonator; the perpendicular bores are 2 forefingers or 3 pinky-fingers wide. The gourds are secured to the eka-tantri's wooden stem using gut cord, passing through holes made in the stem, down through a hole in the top of the gourd; the thread goes through a pair of holes in the top of a coconut, set inside the gourd (with the rounded side, pressing against the sides of the gourd and toward the stem). On the instrument's lower end, the bridge (kakubh) is attached, its surface not flat but rounded like a tortoise shell. On top of the bridge apatuli (metal plate forming a spike) was placed in the center.[6]

Different symbolism appears on the instruments over time. In Hinduism, the instruments have been associated with the godsShiva,Saraswati, andNataraja.[8] Shiva has been portrayed playing it romantically forParavati, and as an ascetic, Natajara in his form as the divine dancer. Saraswati is a goddess of flowing things, including water, wisdom and music. Much less frequently,Krishna has also been portrayed playing the vina and dancing; the instrument is not iconically associated with him, as his instrument is the flute.
The instrument has been portrayed in Buddhist temple art in the hands of humans, as well as celestialkinnaras, half human, half bird figures.
Some kinnari vinas in museums seem to have bird-related carvings and feathers on the ends. Somealapini vinas andeka-tantri vinas have very styled ends that resemble the heads of monsters, similar to theMakara water monster's or theYali's. Both monsters had forms that included an elephant's trunk, a feature found on some kinnari vinas.
