Somewhere between a Bhoiravi at dawn and a Bhairavi at dusk, between a veena’s sustained drone and a sitar’s plucked resonance, between the Carnatic concert at Chennai’s Music Academy and the Kolkata Dover Lane festival, India’s two great classical music traditions meet and diverge. Hindustani and Carnatic music share ancient roots but have evolved into distinct systems over many centuries – each with its own theoretical framework, performance practice, social context, and relationship with modernity. Understanding both systems is essential to understanding how India thinks about sound, time, and the transmission of knowledge across generations. This piece is a primer for those encountering classical Indian music for the first time and a provocation for those who have been listening for years.
What Is a Raga?
The raga is the fundamental organising principle of Indian classical music. It is not a scale – though it uses scales. It is not a melody – though melodies are derived from it. A raga is a framework: a specific set of notes (swaras), a set of rules about which notes can ascend and which descend, a characteristic phrase that identifies the raga, an associated mood (rasa), a time of day or season for performance, and – in skilled hands – a personality that a musician explores and develops over the course of an improvisation that can last minutes or hours. There are hundreds of ragas in both Hindustani and Carnatic traditions, though the two systems name and conceptualise them differently.
The seven basic notes of Indian music – Sa, Re, Ga, Ma, Pa, Dha, Ni – correspond roughly to the solfege Do, Re, Mi, Fa, Sol, La, Ti of Western music, but the similarities end quickly. Indian classical music recognises microtones – shrutis – that fall between the notes of the Western equal-tempered scale. A “Komal Re” (flat Re) and a “Shuddha Re” (natural Re) are different notes, and a musician’s precise intonation within these positions is central to artistic quality. The twelve-note chromatic system of Western music is a subset of what Indian music theoretically accommodates, though in practice different schools and traditions have their own views on exactly which microtonal positions are meaningful.
Hindustani Music: North India’s Living Tradition
Hindustani classical music, as it exists today, developed primarily in North India from approximately the 12th century onward through a synthesis of older Indian musical traditions with influences from Persian and Central Asian court music that accompanied the Sultanate and Mughal periods. This synthesis produced the gharana system – lineage-based schools of music centred on a senior master (ustad or pandit) whose stylistic approach, pedagogical method, and repertoire of compositions defined the gharana’s identity across generations.
The major gharanas of Hindustani vocal music include the Gwalior, Agra, Jaipur-Atrauli, Kirana, Patiala, and Rampur-Sahaswan gharanas, each with distinct approaches to voice production, ornamentation, tempo, and raga elaboration. The Gwalior gharana is often considered the oldest surviving lineage and values clarity of note and composition. The Kirana gharana, associated with Ustad Abdul Karim Khan and his descendants, values a sustained, meditative style with emphasis on note staying and subtle gamak. Patiala gharana, associated with Bade Ghulam Ali Khan, is known for its dramatic, operatic style with fast taans. These distinctions are not superficial; they represent genuinely different aesthetic philosophies about what music is for and how its beauty is revealed.
Instrumental Hindustani music has its own gharanas and masters. The sitar, sarod, bansuri (bamboo flute), shehnai, and sarangi each have rich performance traditions. Ravi Shankar’s global popularisation of the sitar in the 1960s and 1970s – culminating in his collaborations with Yehudi Menuhin and George Harrison – introduced Hindustani music to audiences who had never encountered it before, though musicians within the tradition have complex views about whether that introduction conveyed the tradition’s depth or its more accessible surface.
Carnatic Music: The Southern Tradition
Carnatic music, the classical tradition of South India, developed along a path that was less influenced by Islamic court music and maintained a closer connection to the temple music traditions of the region. Its theoretical framework is systematised in the melakarta system, a mathematical structure of 72 parent scales (melakartas) from which all ragas are derived. This systematisation, developed formally by Venkatamakhi in the 17th century, gives Carnatic theory a more explicitly codified character than Hindustani theory, though performance practice allows enormous expressive freedom within the framework.
The “trinity” of Carnatic music – Tyagaraja, Muthuswami Dikshitar, and Syama Sastri, all composing in the late 18th and early 19th centuries in the Thanjavur region – created the compositional canon around which Carnatic performance is organised. Tyagaraja alone composed over 700 songs, mostly in Telugu, in praise of Rama. Dikshitar composed in Sanskrit with elaborate mantra elements. Their compositions are not merely historical artefacts; they are living pieces performed at every Carnatic concert. A musician’s interpretation of a Tyagaraja kriti is evaluated not just for technical execution but for bhakti – devotional depth – and for musicological insight into the raga’s possibilities.

The Sabha Culture: Chennai’s Music Season
Every December and January, Chennai transforms into perhaps the world’s most concentrated classical music festival. The Margazhi season – named after the Tamil month considered auspicious for music and devotion – runs for approximately six weeks and involves over 4,000 concerts across dozens of sabhas (music societies). The Music Academy on TTK Road, founded in 1928 and presenting its own season of flagship concerts since then, is the institutional heart of the season; a Morning Concert at the Music Academy is among the most prestigious platforms in Carnatic music. Sabhas like Brahma Gana Sabha, Narada Gana Sabha, and the Cleveland Thyagaraja Aradhana in the United States (which draws thousands of musicians and listeners annually) have extended the Carnatic circuit globally as the Tamil diaspora has grown.
Kolkata’s Dover Lane Music Conference, held in January, serves a comparable function for Hindustani music – a concentrated gathering of the tradition’s leading voices that functions as both artistic summit and social institution. The tradition of the baithak – informal musical gatherings at musicians’ homes or in the homes of patrons – has declined in urban centres but persists in some gharana circles, particularly in smaller cities like Varanasi, Jaipur, and Gwalior where the connection between music, spiritual practice, and community is more intact.
AI-Generated Ragas and the Authenticity Question
In 2023 and 2024, multiple experiments with AI-generated ragas and classical music compositions attracted attention in both the Hindustani and Carnatic communities. Google’s Magenta project, Meta’s MusicGen, and various Indian startups have produced software that can generate melodies in a raga grammar – following the ascent and descent rules, reproducing characteristic phrases, even generating accompaniment patterns. The response from classical musicians has ranged from curiosity to deep scepticism. T.M. Krishna, the Carnatic vocalist and social critic who has written extensively about democratising classical music access, has argued that AI’s ability to reproduce the grammar of a raga without any of the embodied, culturally situated practice that gives raga music its meaning is precisely the problem – not the solution. A raga, in this view, is not a set of rules but a living practice of relationship between teacher, student, tradition, and sound.
The streaming data tells a different story about where the audiences are. Spotify’s annual “Wrapped” data in India has consistently shown classical music as a growing listening category, with younger listeners in their 20s accounting for significant shares of classical streaming. Apps like Ragatip (which identifies ragas from audio), Sangeet (a community app for classical musicians), and YouTube channels run by musicians have built audiences of tens of thousands. Whether streaming exposure translates into the kind of deep engagement – years of studying with a teacher, attending concerts, understanding compositions – that sustains the tradition remains an open question. Classical music has survived the transition from court patronage to the colonial recording industry to the cassette era to digital platforms; it will survive streaming. The question is what it preserves and what it transforms in the process.
T.M. Krishna and the Democratisation Debate
T.M. Krishna has been the most publicly articulate voice for a fundamental rethinking of who Carnatic music belongs to and who gets to perform and appreciate it. His concerts in fisherfolk communities in Chennai, his performances in church spaces, his writing challenging the caste and class assumptions embedded in the sabha culture – all have generated both admiration and sharp criticism from within the classical music establishment. The controversy is not trivial: the Carnatic tradition has historically been closely associated with Brahmin patronage and performers, and the questions Krishna raises about whether sabha gatekeeping, concert etiquette norms, and compositional repertoire reflect and reproduce social hierarchies are serious ones that touch on the tradition’s long-term health and social legitimacy.
Where to Start Listening
If you are new to Indian classical music: for Carnatic, begin with M.S. Subbulakshmi’s recordings of Tyagaraja kritis or M. Balamuralikrishna’s concerts. For Hindustani, begin with Pandit Bhimsen Joshi’s khayal recordings or Ustad Bismillah Khan’s shehnai. For contemporary artists engaging with both traditions and wider audiences, seek out T.M. Krishna (Carnatic) and Anoushka Shankar (Hindustani). The All India Radio archive has decades of concert recordings freely accessible; use it.
Generational Transmission: The Guru-Shishya Relationship
The guru-shishya (teacher-student) relationship is the primary vehicle through which Indian classical music is transmitted across generations. This is not merely a pedagogical arrangement – it is a comprehensive relationship that shapes the student’s artistic sensibility, personal discipline, and relationship with the tradition over years or decades of close study. A student in a traditional setting learns not just notes and techniques but the guru’s entire artistic world: their compositions, their interpretation of ragas, their approach to improvisation, their understanding of the tradition’s history and its debates. The student becomes a custodian and interpreter of a living lineage.
The digitisation of music has created a parallel universe of learning. YouTube has thousands of hours of classical music pedagogy and performance. Apps like Simply Sarangi and Swarganga provide structured learning pathways. The Indian Council for Cultural Relations funds music schools abroad. The question is whether digital learning can produce the same depth of artistic formation as years of face-to-face gurukul training – and the honest answer is that nobody knows yet, because the first generation trained primarily digitally has not yet reached artistic maturity. What is clear is that more people have access to Indian classical music now than at any point in its history, and the tradition is entering unfamiliar territory with that democratisation.

Gen Z and the Spotify Question
Spotify’s 2023 India data showed classical Indian music among the fastest-growing listening categories for users aged 18-25. This is surprising given that classical music has historically been an acquired taste requiring significant investment of time and prior knowledge to appreciate. The explanation probably involves multiple factors: the yoga and mindfulness movement’s embrace of Indian sounds (even in simplified or adapted forms) has created a gateway; the nationalist cultural moment of the 2010s and 2020s has made Indian classical music a marker of cultural pride; and platform recommendation algorithms have exposed listeners who would never have sought out classical music to it through adjacent listening paths. Whether these listeners deepen their engagement beyond background listening is the key question. The tradition can sustain and even grow with casual listeners; it cannot sustain without serious listeners who attend concerts, support musicians, and eventually become patrons and practitioners.
North-South Exchange: What Each Tradition Offers the Other
The two traditions have historically had relatively limited cross-pollination at the level of formal performance practice, though individual musicians have studied elements of both. Pandit Shivkumar Sharma’s santoor was not a classical instrument until he transformed it into one, drawing on both Hindustani theoretical frameworks and the musical sensibility of Kashmir. Ravi Shankar collaborated with Carnatic violinists and was deeply familiar with South Indian musical theory. In contemporary performance, musicians like Chitravina Ravikiran have developed “Melharmony” – a compositional approach that finds structural connections between Hindustani and Carnatic raga systems. TM Krishna has performed compositions by Hindustani composers in Carnatic settings. The walls between the traditions, while real, are not impermeable.
The most productive cross-pollination happens at the level of percussion, where the tabla (Hindustani) and mridangam (Carnatic) have been used in fusion contexts, and where rhythmic theory from both traditions has been explored by composers working across genres. Tabla maestro Zakir Hussain’s collaborations with Carnatic percussionists like Vikku Vinayakram and with jazz musicians including John McLaughlin (in the Shakti ensemble) created listening that drew on both traditions without reducing to either. Whether the future of Indian classical music lies in such cross-tradition exploration or in the deepening of each tradition’s internal development is a debate that practitioners continue to have. Both paths have produced extraordinary art.
