Hindustani Classical Music

Hindustani classical music is the classical art-music tradition of North India, Pakistan, Bangladesh, Nepal, and Afghanistan, and stands as one of the two principal streams of Indian classical music alongside the Carnatic system of the south. Its theoretical foundation descends from the Natyashastra of Bharata (composed between roughly 200 BCE and 200 CE) and the Sangita Ratnakara of Sharngadeva (13th century), the last great Sanskrit treatise common to both northern and southern traditions. From the 13th and 14th centuries onward, the northern tradition diverged under sustained Perso-Arabic and Central Asian influence carried into the Delhi Sultanate and later the Mughal court. The polymath Amir Khusrau (1253–1325), associated with the Chishti Sufi order, is traditionally credited with innovations in form and instrumentation, while the Mughal emperor Akbar's court patronage of Mian Tansen in the 16th century crystallised the courtly, soloist-centred character the tradition retains. For UPSC General Studies Paper I, the subject falls squarely within the Art and Culture syllabus on Indian heritage.

The grammar of the tradition rests on two organising axes: melody and rhythm. The melodic axis is the raga, a framework of selected notes (swaras) governed by rules of ascent (aroha) and descent (avaroha), characteristic phrases (pakad or chalan), resting notes (vadi and samvadi), and an associated mood (rasa) and prescribed time of day or season. Hindustani theory organises ragas under the thaat classification of ten parent scales codified by Vishnu Narayan Bhatkhande in the early 20th century. The rhythmic axis is the tala, a cyclic metric pattern of beats divided into measures (vibhags) and marked by stressed beats (sam and tali) and an unstressed beat (khali); common talas include teental (16 beats), jhaptal (10), ektal (12), and dadra (6). The seven basic swaras—Sa, Re, Ga, Ma, Pa, Dha, Ni—are realised with komal (flat) and tivra (sharp) variants, and Sa is a movable, performer-chosen tonic rather than a fixed pitch.

A performance proceeds through structured stages. The vocalist or instrumentalist begins with the alap, an unmetered, slow exposition that introduces the raga without rhythmic accompaniment, followed by the jor and jhala in instrumental practice as pulse and tempo gather. The composed section, or bandish, then unfolds against the tala kept on the tabla, moving from a slow (vilambit) to a fast (drut) tempo, with improvisation through techniques such as taan, sargam, and bol-banao. Vocal genres include the older, austere dhrupad; the more ornamented and now dominant khayal; and lighter forms such as thumri, dadra, tarana, and tappa. Principal instruments include the sitar, sarod, sarangi, santoor, bansuri, shehnai, and the tabla, with the tanpura providing the constant drone. Transmission occurs through the guru-shishya parampara, the oral apprenticeship binding teacher and disciple, and stylistic schools known as gharanas—among them Gwalior, Agra, Kirana, Jaipur-Atrauli, and Patiala for vocal music, and the Maihar gharana for instruments.

Twentieth- and twenty-first-century practice carried the tradition from princely courts and Mughal durbars onto concert stages and the global circuit. Pandit Ravi Shankar (1920–2012), trained at Maihar under Ustad Allauddin Khan, brought the sitar to Western audiences through collaborations with Yehudi Menuhin and George Harrison and performances at the Monterey (1967) and Woodstock (1969) festivals. Ustad Bismillah Khan (1916–2006), the shehnai maestro, and the sarod player Ustad Amjad Ali Khan, the vocalist Pandit Bhimsen Joshi of the Kirana gharana, and tabla virtuoso Ustad Zakir Hussain became national figures; Joshi, Shankar, and Bismillah Khan all received the Bharat Ratna. The Sangeet Natak Akademi, established in 1953, and All India Radio remain central institutional patrons in New Delhi.

Hindustani music must be distinguished from the Carnatic tradition of South India, with which it shares the raga-tala foundation but diverges sharply in practice. Carnatic performance is predominantly composition-based and devotional, built on the kriti form and the 72 melakarta parent scales, whereas Hindustani practice privileges extended improvisation and the meditative alap, classifies ragas under ten thaats, and assigns ragas to times of day. Carnatic music absorbed less Persian influence and retains a more fixed compositional repertoire associated with the 18th-century Trinity of Tyagaraja, Muttuswami Dikshitar, and Syama Sastri. The two systems also differ in instrumentation, with the veena, mridangam, and violin dominant in the south.

Contemporary debates surround the tradition's preservation and reach. The decline of dhrupad, the economics of the guru-shishya system in an era of formal music schools, and questions of access, caste, and gender among hereditary musician communities (such as the sarangi and tabla lineages) remain live concerns. Cross-border heritage is politically sensitive: many gharanas and performers, including Ustad Bade Ghulam Ali Khan and the Patiala lineage, are shared between India and Pakistan. Fusion experiments and film music have widened audiences while raising purist anxieties about dilution, and digital streaming has reshaped patronage away from the live concert (the baithak and the modern jugalbandi duet).

For the working civil-services aspirant or culture-desk practitioner, Hindustani classical music is a recurring GS1 topic demanding command of specific terminology—raga, tala, thaat, gharana, dhrupad, khayal—alongside the ability to name representative exponents and instruments and to draw the precise contrast with Carnatic music. Beyond examinations, it constitutes a core element of India's intangible cultural heritage and soft-power diplomacy, regularly deployed in cultural exchange programmes and festivals abroad by the Indian Council for Cultural Relations.
