String instruments

Classification and historical foundations

Indian string instruments are united by their sound-producing principle rather than by a single shape or performance technique. A stretched string vibrates, and a resonating body amplifies its sound. Pitch depends principally on the string’s vibrating length, tension and mass per unit length. Instruments may therefore differ in material and appearance while belonging to the same broad organological family, called chordophones in modern comparative musicology.

The Natya Shastra, attributed to Bharata and compiled over a debated period around the early centuries of the Common Era, gives the foundational fourfold classification: tata, avanaddha, sushira and ghana. Tata refers to stretched-string instruments; avanaddha to instruments with stretched membranes; sushira to wind instruments; and ghana to solid instruments such as cymbals. Many teaching systems distinguish plucked tata instruments from bowed vitata instruments. For examinations, identify which classificatory convention a question uses.

Veena is an old and historically broad designation, not the name of one unchanged instrument across all periods. Literary references and sculptures document diverse string-instrument forms, including harp-like instruments. These should not automatically be equated with the modern Saraswati or Rudra veena. The Tamil yazh, known from early Tamil literature, belongs to the historical harp tradition. Claims that one individual invented a major modern instrument often simplify a long process of adaptation.

How strings create melody, ornament and drone

Indian string instruments can be grouped by playing action. Sitar, sarod and veena are plucked; sarangi, violin and kamayacha are bowed; santoor strings are struck with light wooden mallets. This distinction separates technique from the vibrating medium: striking does not make the santoor an avanaddha instrument, because its primary vibrating elements are strings rather than membranes.

Frets provide positions for stopping strings and organising pitch. The sitar has movable, curved frets, while the Saraswati veena has fixed frets mounted on its fingerboard. The sarod has a fretless metal fingerboard, and its strings are stopped with the fingernails. Fretless instruments facilitate continuous pitch movement, but fretted instruments can also produce glides through string deflection and other techniques. Thus, fretted does not mean incapable of ornamentation.

Meend is a glide between notes; gamaka broadly denotes melodic ornamentation, with particular technical importance in Carnatic music. Instrumental technique adapts these expressive features to a raga’s grammar. Sympathetic strings, found on instruments such as the sitar, sarod and sarangi, resonate without normally being directly played. They enrich tone but are distinct from the main melody strings. The tanpura supplies a recurring drone, usually around the tonic and selected supporting notes, establishing a stable pitch reference without playing the raga melody.

Major instruments of the Hindustani tradition

The sitar is a long-necked, plucked instrument with movable frets, a resonating body and sympathetic strings. It is generally played with a wire plectrum called a mizrab. Ravi Shankar and Vilayat Khan represent influential performance traditions. The surbahar is a larger, lower-pitched instrument related to the sitar, particularly suited to expansive alap. The Rudra veena, with a long tubular body and two large gourd resonators, is strongly associated with dhrupad.

The sarod is a plucked, fretless instrument with a skin-covered resonator and a metal fingerboard. It developed through adaptations associated with the rabab tradition. Allauddin Khan, Ali Akbar Khan and Amjad Ali Khan are major names linked to it. The sarangi is a bowed, fretless instrument held vertically; its principal strings are stopped using the sides of the fingernails. Its vocal-like expressiveness made it important in accompaniment as well as solo performance. Ram Narayan helped establish its modern solo prominence.

The santoor is a trapezoidal instrument with numerous strings stretched across bridges and struck with a pair of light mallets. It is associated with Kashmir’s Sufiana musical tradition. Shivkumar Sharma adapted its technique and presentation for Hindustani classical concert performance. The instrument illustrates why regional origin and present performance setting must be distinguished: an instrument rooted in a regional tradition can enter a wider classical repertoire.

Carnatic and regional string traditions

The Saraswati veena, closely associated with southern India, has a large wooden resonator, a fretted neck and a secondary support resonator. It normally has seven strings: four for melody and three side strings used for drone and rhythmic punctuation. Thanjavur is a major centre of veena craftsmanship. The instrument supports elaborate gamakas and occupies an important place in Carnatic solo performance.

The chitravina, also called gottuvadyam, is a fretless instrument played horizontally using a slide. Despite its alternative name, it belongs to the string family. The European violin was successfully adapted to Carnatic music; Baluswami Dikshitar is widely credited with an important role in this process during the early nineteenth century. Carnatic violinists generally perform seated, supporting the instrument between the chest or shoulder region and the foot, which permits flexible fingering and gamaka production.

Folk string traditions have their own social settings and should not be treated merely as simplified classical music. The ektara is associated with devotional and itinerant singing, including Baul traditions in Bengal. Rajasthan’s Manganiyar musicians are associated with the bowed kamayacha, while the ravanhatta is linked to regional bardic traditions. The pena is a bowed instrument of Manipur, important in ritual and cultural performance. Names such as ektara and dotara can cover regional variants, so literal interpretation of a name may not reliably establish every specimen’s string count.

Cultural significance and examination approach

Instrument traditions preserve knowledge beyond performance: wood selection, gourd cultivation, string preparation, bridge shaping, tuning and apprenticeship all contribute to their continuity. The transmission of this knowledge depends on both musicians and makers. Institutional teaching and recordings can broaden access, but declining demand for particular instruments can threaten specialised craftsmanship even when the associated musical tradition remains visible.

For Prelims, organise revision around five links: instrument, playing technique, structural feature, region or tradition, and exponent. Distinguish the tanpura’s drone function from melodic instruments, the santoor’s strings from percussion membranes, and the sarangi’s bowing from the sarod’s plucking. Avoid treating Hindustani and Carnatic associations as absolute geographical boundaries: instruments travel, and the violin is used in both systems. Also separate documented historical development from popular legends, especially the frequently repeated attribution of the sitar’s invention to Amir Khusrau, which is not an established historical fact.
