A complete overview of Indian classical music for UPSC — covering its Vedic origins in the Sama Veda, Bharata's Natyashastra, the twin pillars of raga and tala, the 22 shrutis, the Bhakti movement's influence, and a comparison of the Hindustani and Carnatic traditions.
Indian classical music is one of the world's oldest continuous musical traditions, rooted in the Sama Veda and systematised in Bharata's Natyashastra. It rests on two universal pillars — raga (a melodic framework specifying notes, sequences, and emotional colour) and tala (the rhythmic cycle) — and has evolved over millennia into two distinct schools: the Persian-influenced Hindustani tradition of the north and the relatively unaltered Carnatic tradition of the south.
What Are the Vedic Origins of Indian Classical Music?
The earliest codified musical practice in India is found in the Sama Veda (c. 1200–1000 BCE), one of the four Vedas and the only one devoted almost entirely to musical chants called samans. These were sung by udgatar priests during Vedic sacrifices. The Sama Veda distinguished three pitch accents — udatta (raised), anudatta (lowered), and svarita (combined) — which formed the embryo of the later seven-note system (saptasvaras: Sa, Re, Ga, Ma, Pa, Dha, Ni). This makes the Sama Veda the first musical text in Indian civilisation.
The second foundational milestone is Bharata Muni's Natyashastra (c. 2nd century BCE – 2nd century CE), a comprehensive treatise on dramaturgy, dance, and music. Several chapters are devoted to the theory of music (gandharva and gana), introducing: sruti (micro-tonal interval), svara (note), grama (modal scale system), and murchana (modal transposition). Crucially, the Natyashastra recognised 22 shrutis — the micro-tonal divisions of an octave — establishing a theoretical framework that Indian music theory has built upon ever since.
What Are Raga and Tala — the Twin Pillars?
Raga (Sanskrit: raja, "to colour") is the melodic framework that governs a performance. It specifies: which notes (svaras) may be used, their ascending (aroha) and descending (avaroha) order, characteristic phrases (pakad), the dominant and secondary notes (vadi and samvadi), ornamentation patterns, and an associated emotional quality (rasa). A raga is also traditionally linked to a specific time of day, season, or ritual context. Over 300 ragas are in active performance across both traditions.
Tala is the rhythmic cycle that governs the time-dimension of a performance. Each tala consists of a fixed total number of beats grouped into sub-sections (vibhag). The first beat of each cycle — called sam — is the moment of resolution and convergence between soloist and percussionist. Common talas include teentaal (16 beats, Hindustani) and adi tala (8 beats, Carnatic). Indian classical music is fundamentally an improvised art: the musician explores a raga's melodic landscape within the rhythmic container of the tala, making each performance unique.
How Did the Two Traditions Diverge?
Indian classical music was broadly unified until the early medieval period. The arrival of Turko-Afghan rulers from the 12th century onward brought Persian and Central Asian musical influences to northern India, causing the gradual divergence into two streams:
- Hindustani music (North India): absorbed Persian melodic sensibilities and introduced new instruments such as the sarangi and, later, the tabla. Urdu and Hindi became dominant languages of composition. The khayal style — emphasising melodic improvisation — became its principal vocal genre.
- Carnatic music (South India): remained relatively insulated from foreign influence, continuing older Sanskrit and Dravidian traditions. The kriti — a tightly structured devotional composition — is its core vocal form. Telugu, Tamil, Kannada, and Sanskrit predominate.
How Did the Bhakti Movement Transform Indian Classical Music?
The Bhakti movement (8th–17th centuries CE) was the most transformative socio-spiritual force in the history of Indian classical music. Bhakti saint-composers took music out of temple precincts and royal courts and placed it in the hands of common devotees, permanently altering both its social role and its expressive range.
Key impacts:
- Vernacularisation: compositions shifted from Sanskrit to regional languages — Hindi, Braj Bhasha, Marathi, Telugu, Tamil — dramatically widening music's social reach.
- Emotional deepening: the Bhakti ethos of anuraga (intense devotional love) enriched the emotional content of ragas, particularly those evoking longing and surrender.
- The Carnatic Trinity: Thyagaraja, Muthuswami Dikshitar, and Syama Sastri (18th–19th centuries) composed thousands of kritis that form the core Carnatic concert repertoire to this day. Purandaradasa (16th century) is revered as the "Father of Carnatic Music" for standardising pedagogical exercises.
- Northern saint-composers: Kabir, Mirabai, Surdas, and Tukaram produced devotional poetry set to ragas, enriching Hindustani music's devotional dimension (bhajan, pada, abhangs).
The 22 Shrutis — India's Micro-tonal System
A defining feature of Indian music theory is the concept of 22 shrutis — 22 micro-tonal intervals distributed across one octave. While Western equal temperament divides an octave into 12 semitones, Indian theory recognises far finer pitch gradations. The 22 shrutis are distributed unevenly across the seven svaras: Sa and Pa each occupy one shruti, while Re, Ga, Ma, Dha, and Ni accommodate two or three each depending on the theoretical system.
These micro-intervals are not usually rendered as discrete steps but as the pitch-space within which ornaments operate. In Carnatic music, gamaka (oscillation or shaking between adjacent shrutis) is the principal vehicle. In Hindustani music, meend (glide) and andolan (gentle oscillation) serve a similar function. The shruti system is what gives Indian classical music its characteristic capacity for emotional nuance and subtlety.

| Geographic base | North, Central, East India | South India (Tamil Nadu, Karnataka, Andhra Pradesh, Kerala) |

Frequently Asked Questions
Which is the first musical text in Indian history?
The Sama Veda (c. 1200–1000 BCE) is considered the first musical text in Indian history. Devoted entirely to musical chants called samans, it classified pitch into udatta, anudatta, and svarita — the earliest codified tonal distinctions and forerunners of the later seven-note saptasvara system used in all Indian classical music.
What is the significance of Bharata's Natyashastra for Indian classical music?
The Natyashastra (c. 2nd century BCE – 2nd century CE) is the foundational treatise on Indian performing arts. For music, it introduced the 22 shrutis, the seven svaras, the grama (scale) system, and jati (melodic archetypes that preceded ragas), establishing music as a formal, theorised discipline for the first time and providing the theoretical vocabulary that all subsequent musicology has built upon.
How did the Bhakti movement influence Indian classical music?
The Bhakti movement democratised Indian classical music by shifting composition from Sanskrit to vernacular languages and taking it from temples and courts to ordinary devotees. It deepened music's emotional register through devotional fervour, and its saint-composers — including the Carnatic Trinity (Thyagaraja, Dikshitar, Syama Sastri) and northern saints such as Mirabai and Surdas — created repertoires that remain central to both traditions today.
What are the 22 shrutis in Indian music theory?
The 22 shrutis are micro-tonal intervals within a single octave, first enumerated in Bharata's Natyashastra. They are finer subdivisions than the 12 semitones of Western equal temperament and give Indian music its capacity for subtle pitch expression. In performance, they manifest through ornamental techniques: gamaka (oscillation) in Carnatic music and meend (glide) and andolan in Hindustani music.
What is the difference between raga and tala?
Raga is the melodic framework — it defines which notes to use, in what sequence, with what ornamentation, and at what time, giving a performance its emotional identity. Tala is the rhythmic cycle — a fixed pattern of beats providing the temporal structure within which the musician improvises. Raga governs the melodic dimension; tala governs the rhythmic dimension. Together they form the dual axis of all Indian classical music.
