Hindustani classical music is one of the two major traditions of Indian classical music, primarily practiced in the northern regions of the Indian subcontinent. It is a melodic system centered around *raga* (modal framework) and *tala* (rhythmic cycle), with a strong emphasis on improvisation. Historically rooted in ancient Vedic chants and the *Natyashastra*, Hindustani music developed distinctive forms such as *dhrupad*, *khayal*, and *thumri* under the influence of Persian and Mughal court traditions. It is performed both vocally and instrumentally, with prominent instruments including the sitar, sarod, bansuri, and tabla.
1 History
1.1 Ancient and Vedic Origins
1.1.1 Sama Veda and the Natyashastra
The earliest roots of Hindustani classical music lie in the *Sama Veda* (c. 1500–1200 BCE), whose chants employed a structured melodic framework. The *Natyashastra* (c. 200 BCE–200 CE), attributed to Bharata Muni, codified performance arts and established the foundational concepts of *raga*, *tala*, and emotional expression (*rasa*). These texts provided the theoretical bedrock for the later evolution of North Indian music.
1.2 Medieval Period and Mughal Influence
1.2.1 Amir Khusrow and the Synthesis of Traditions
The 13th‑century poet‑musician Amir Khusrow (1253–1325 CE) is traditionally credited with blending indigenous Indian musical elements with Persian and Central Asian practices introduced during the Delhi Sultanate. He is said to have invented the sitar and tablā, and his innovations helped shape new genres and a courtly style that would flourish under the Mughal Empire.
1.3 Colonial and Modern Developments
1.3.1 The Role of Princely Courts and Gharanas
During the 18th and 19th centuries, the patronage of princely states such as Gwalior, Jaipur, and Rampur fostered the emergence of *gharanas* (hereditary schools), each preserving distinctive stylistic features. The decline of court patronage under British rule led to a shift toward public concerts and recording technology in the early 20th century, which preserved and disseminated the tradition.
2 Theory and Structure
2.1 Raga – Melodic Framework
2.1.1 Classification by Thaat (Parent Scale)
Ragas are systematically classified under ten *thāts* (parent scales) as defined by Vishnu Narayan Bhatkhande in the early 20th century. Each thaat is a heptatonic scale from which a raga derives its permissible notes.
2.1.2 Raga Families and Time Theory
Ragas are assigned to specific times of day or seasons to enhance their expressive mood (*rasa*). They also form families based on shared ascending/descending patterns and dominant notes (*vadi* and *samvadi*).
2.2 Tala – Rhythmic Cycles
2.2.1 Common Talas: Tintal, Jhaptal, Ektaal
Tala is a recurring rhythmic cycle with a fixed number of beats. The most common is *tintal* (16 beats, divided 4+4+4+4); other important talas include *jhaptal* (10 beats: 2+3+2+3) and *ektaal* (12 beats: 2+2+2+2+2+2).
2.2.2 Layakari (Tempo Variations)
*Layakari* refers to the art of rhythmic manipulation, where a performer improvises variations in tempo—such as halving (*dwigun*), tripling (*tigun*), or quadrupling (*chowgun*) the speed of the composition while maintaining the tala cycle.
2.3 Ornamentation and Gamakas
2.3.1 Meend, Gamak, and Khatka
*Meend* is a smooth glide between two notes; *gamak* is a forceful, oscillating shake; and *khatka* is a rapid, decorative cluster of notes. These ornaments (*alankaras*) are essential for expressive raga rendition.
3 Major Vocal Forms
3.1 Dhrupad
3.1.1 Alap and Dhamar
Dhrupad, the oldest surviving vocal form, opens with *alap* (a slow, rhythm‑free melodic exploration) and may include a *dhamar* composition set to a 14‑beat tala. It emphasizes solemnity, precise pitch, and yoga‑like breath control.
3.2 Khayal
3.2.1 Vilambit (Slow) and Drut (Fast) Sections
Khayal, the dominant vocal form since the 18th century, typically alternates between a slow (*vilambit*) section—featuring detailed *alap* and *taans*—and a fast (*drut*) section with a shorter composition and lively rhythmic interplay.
3.3 Semi‑Classical Forms
3.3.1 Thumri
Thumri is a lighter, romantic genre often associated with the courtesans of Lucknow. It uses simpler ragas and emphasizes *bol* (text) and emotive nuance (*harkat*).
3.3.2 Dadra and Ghazal
Dadra is set to a six‑beat tala of the same name, with a playful, folk‑inflected style. The ghazal, originally Persian, was adopted into Hindustani music as a poetic form of love and longing, set to classical and semi‑classical tunes.
4 Instrumental Music
4.1 String Instruments
4.1.1 Sitar
The sitar is a long‑necked lute with plucked strings and sympathetic strings. It became internationally known through maestro Ravi Shankar, who popularized its use in Hindustani instrumental *gayaki ang* (vocal‑style playing).
4.1.2 Sarod
The sarod is a fretless lute with a deep, resonant tone. Its playing style emphasizes rapid *taans* and left‑hand slides (*meend*).
4.1.3 Veena
The *rudra veena*, a stick‑zither with two large gourds, is the classical instrument for dhrupad. Plucked with a wire plectrum, it produces a rich, meditative sound.
4.2 Wind Instruments
4.2.1 Bansuri (Flute)
The bansuri, a bamboo transverse flute, is associated with the god Krishna. Its Hindustani style employs a controlled, breathy tone and intricate ornamentation.
4.2.2 Shehnai
The shehnai is a double‑reed oboe, traditionally played at weddings and temples. Under Bismillah Khan, it gained concert‑hall prominence.
4.3 Percussion
4.3.1 Tabla
The tabla consists of a pair of hand‑drums—a smaller right drum (*dayan*) and a larger left drum (*bayan*). It is the chief rhythmic accompaniment, capable of complex syllables (*bols*) and improvised variations.
4.3.2 Pakhavaj
The pakhavaj is a barrel‑shaped double‑headed drum used in dhrupad accompaniment. Its deep, resonant sound marks a slower, more solemn rhythmic style.
5 Performance Practices
5.1 Concert Structure
5.1.1 Alap (Free Rhythm Introduction)
A performance begins with *alap* (or *alapana*), a slow, unmetered exploration of the raga’s notes and mood, establishing its identity.
5.1.2 Jod, Jhala, and Gat (Composition with Rhythm)
In instrumental music, *jod* introduces a gentle pulse, *jhala* accelerates with rhythmic strumming, and the *gat* (fixed composition) introduces a formal tala cycle. In vocal khayal, the *bandish* serves a similar compositional anchor.
5.2 Role of Improvisation
5.2.1 Taans and Boltaans
*Taans* are fast, florid runs of notes, often improvised. *Boltaans* incorporate the lyrics (*bol*) of the composition into these rapid passages, blending melody and text.
5.3 Sangat (Accompaniment)
5.3.1 Tabla Accompaniment
The tabla player (*tabaliya*) follows the vocalist or instrumentalist, maintaining the tala cycle while executing *theka* (basic pattern) and occasional *saath sangat* (synchronized interplay).
5.3.2 Harmonium Role
The harmonium, introduced by British missionaries, is widely used in vocal accompaniments and solo performances. It provides drone and melodic support, though its fixed pitch limits *meend* effects.
6 Gharanas (Schools of Tradition)
6.1 Gwalior Gharana
The oldest khayal gharana, founded in the 16th century. It is known for clear, straightforward *bol* rendition and emphasis on *taan*.
6.2 Agra Gharana
Known for powerful voice projection and a merger of dhrupad elements (e.g., heavy *gamak*) into khayal.
6.3 Jaipur‑Atrauli Gharana
Emphasizes complex ragas and intricate *taankari* (rapid note passages), often with a rhythmic approach that challenges the tala.
6.4 Patiala Gharana
Famous for its elaborate *taans* and emotional thumri style, blending *khayal* and semi‑classical forms.
6.5 Kirana Gharana
Prioritizes *swar* (melodic note) purity and slow, meditative *alap*. Influenced by the vocalist Abdul Karim Khan.
6.6 Maihar Gharana (Instrumental)
Founded by Allauddin Khan, this gharana centers on *sarod* and *sitar* playing, advocating for a rigorous, *guru‑shishya* training system and a large‑scale concert format (the *Maihar band*).
