Indian classical music
Indian classical music is the classical music of the Indian subcontinent. It has two major traditions: the North Indian classical music known as "Hindustani" and the South Indian expression known as "Carnatic". These traditions were not distinct until about the 15th century. During the period of Mughal rule of the Indian subcontinent, the traditions separated and evolved into distinct forms. Hindustani music emphasizes improvisation and exploration of all aspects of a raga, while Carnatic performances tend to be short composition-based. However, the two systems continue to have more common features than differences. The roots of the  classical music of India are found in the Vedic literature of Hinduism and the ancient "Natyashastra", the classic Sanskrit text on performing arts by Bharata Muni. The 13th century Sanskrit text "Sangeeta-Ratnakara" of Sarangadeva is regarded as the definitive text by both the Hindustani music and the Carnatic music traditions. Indian classical music has two foundational elements, "raga" and "tala". The "raga", based on a varied repertoire of "swara" (notes including microtones), forms the fabric of a deeply intricate melodic structure, while the "tala" measures the time cycle. The "raga" gives an artist a palette to build the melody  from sounds, while the "tala" provides them with a creative framework for rhythmic improvisation using time. In Indian classical music the space between the notes is often more important than the notes themselves, and it traditionally eschews Western classical concepts such as harmony, counterpoint, chords, or modulation. History. The root of music in ancient India are found in the Vedic literature of Hinduism. The earliest Indian thought combined three arts, syllabic recital ("vadya"), melos ("gita") and dance ("nrtta"). As these fields developed, "sangeeta" became a distinct genre of art, in a form equivalent to contemporary music. This likely occurred before  the time of Yāska (c. 500 BCE), since he includes these terms in his nirukta studies, one of the six Vedanga of ancient Indian tradition. Some of the ancient texts of Hinduism such as the "Samaveda" (c. 1000 BCE) are structured entirely to melodic themes, it is sections of "Rigveda" set to music. The "Samaveda" is organized into two formats. One part is based on the musical meter, another by the aim of the rituals. The text is written with embedded coding, where "swaras" (octave notes) are either shown above or within the text, or the verse is written into  parvans (knot or member); in simple words, this embedded code of swaras is like the skeleton of the song. The swaras have about 12 different forms and different combinations of these swaras are made to sit under the names of different ragas. The specific code of a song clearly tells us what combination of swaras are present in a specific song. The lyrical part of the song is called "sahityam" and sahityam is just like singing the swaras altogether but using the lyrics of the song. The code in the form of swaras have even the notation of which note  to be sung high and which one low. The hymns of "Samaveda" contain melodic content, form, rhythm and metric organization. This structure is, however, not unique or limited to "Samaveda". The "Rigveda" embeds the musical meter too, without the kind of elaboration found in the "Samaveda". For example, the Gayatri mantra contains three metric lines of exactly eight syllables, with an embedded ternary rhythm. In the ancient traditions of Hinduism, two musical genre appeared, namely "Gandharva" (formal, composed, ceremonial music) and "Gana" (informal, improvised, entertainment music). The "Gandharva" music also implied celestial, divine associations, while the "Gana" also implied singing . The Vedic Sanskrit musical tradition had spread widely in the Indian subcontinent, and according to Rowell, the ancient Tamil classics make it "abundantly clear that a cultivated musical tradition existed in South India as early as the last few pre-Christian centuries". The classic Sanskrit text "Natya Shastra" is at the foundation of the numerous classical music and dance traditions of India. Before "Natyashastra" was finalized, the ancient Indian traditions had classified musical instruments into four groups based on their acoustic principle (how they work, rather than the material they are made of) for example flute which works with gracious  in and out flow of air. These four categories are accepted as given and are four separate chapters in the "Natyashastra", one each on stringed instruments (chordophones), hollow instruments (aerophones), solid instruments (idiophones), and covered instruments (membranophones). Of these, states Rowell, the idiophone in the form of "small bronze cymbals" were used for "tala". Almost the entire chapter of "Natyashastra" on idiophones, by Bharata, is a theoretical treatise on the system of "tala". Time keeping with idiophones was considered a separate function than that of percussion (membranophones), in the early Indian thought on music theory. The early 13th century Sanskrit  text "Sangitaratnakara" (literally, "Ocean of Music and Dance"), by Sarngadeva patronized by King Sighana of the Yadava dynasty in Maharashtra, mentions and discusses "ragas" and "talas". He identifies seven "tala" families, then subdivides them into rhythmic ratios, presenting a methodology for improvization and composition that continues to inspire modern era Indian musicians. "Sangitaratnakara" is one of the most complete historic medieval era Hindu treatises on this subject that has survived into the modern era, that relates to the structure, technique and reasoning behind "ragas" and "talas". The centrality and significance of music in ancient and early medieval India is also  expressed in numerous temple and shrine reliefs, in Buddhism, Hinduism and Jainism, such as through the carving of musicians with cymbals at the fifth century Pavaya temple sculpture near Gwalior, and the Ellora Caves. Texts. The post-Vedic era historical literature relating to Indian classical music has been extensive. The ancient and medieval texts are primarily in Sanskrit (Hinduism), but major reviews of music theory, instruments and practice were also composed in regional languages such as Braj, Kannada, Odia, Pali (Buddhism), Prakrit (Jainism), Tamil and Telugu. While numerous manuscripts have survived into the modern era, many original works on Indian  music are believed to be lost, and are known to have existed only because they are quoted and discussed in other manuscripts on classical Indian music. Many of the encyclopedic Puranas contain large chapters on music theory and instruments, such as the "Bhagavata Purana", the "Markandeya Purana", the "Vayu Purana", the "Linga Purana", and the "Visnudharmottara Purana". The most cited and influential among these texts are the "Sama Veda", "Natya shastra" (classic treatise on music theory, Gandharva), "Dattilam", "Brihaddesi" (treatise on regional classical music forms), and "Sangita Ratnakara" (definitive text for Carnatic and Hindustani traditions). Most historic music theory texts  have been by Hindu scholars. Some classical music texts were also composed by Buddhists and Jain scholars, and in 16th century by Muslim scholars. These are listed in the attached table. Major traditions. The classical music tradition of the ancient and medieval Indian subcontinent (modern Bangladesh, India, Pakistan) were a generally integrated system through the 14th century, after which the socio-political turmoil of the Delhi Sultanate era isolated the north from the south. The music traditions of the North and South India were not considered distinct until about the 16th century, but after that the traditions acquired distinct forms . North Indian classical music is called "Hindustani", while the South Indian expression is called "Carnatic" (sometimes spelled as "Karnatic"). According to Nazir Ali Jairazbhoy, the North Indian tradition acquired its modern form after the 14th or the 15th century. Indian classical music has historically adopted and evolved with many regional styles, such as the Bengali classical tradition. This openness to ideas led to assimilation of regional folk innovations, as well as influences that arrived from outside the subcontinent. For example, Hindustani music assimilated Arabian and Persian influences. This assimilation of ideas was upon the ancient classical foundations such as "raga , tala", "matras" as well as the musical instruments. For example, the Persian "Rāk" is probably a pronunciation of "Raga". According to Hormoz Farhat, "Rāk" has no meaning in modern Persian language, and the concept of "raga" is unknown in Persia. Carnatic music. Purandara Dasa (1484–1564) was a Hindu composer and musicologist who lived in Hampi of the Vijayanagara Empire. He is considered "Pithamaha" (literally, "grandfather") of the Carnatic music. Purandara Dasa was a monk and a devotee of the Hindu god Krishna (Vishnu, Vittal avatar). He systematised classical Indian music theory and developed exercises for musicians to learn and perfect  their art. He travelled widely sharing and teaching his ideas, and influenced numerous South Indian and Maharashtra Bhakti movement musicians. These exercises, his teachings about "raga", and his systematic methodology called "Suladi Sapta Tala" (literally, "primordial seven talas") remains in use in contemporary times. The efforts of Purandara Dasa in the 16th century began the Carnatic style of Indian classical music. Carnatic music, from South India, tends to be more rhythmically intensive and structured than Hindustani music. Examples of this are the logical classification of ragas into melakartas, and the use of fixed compositions similar to Western classical music. Carnatic  raga elaborations are generally much faster in tempo and shorter than their equivalents in Hindustani music. In addition, accompanists have a much larger role in Carnatic concerts than in Hindustani concerts. Today's typical concert structure was put in place by the vocalist Ariyakudi Ramanuja Iyengar. The opening piece is called a varnam, and is a warm-up for the musicians. A devotion and a request for a blessing follows, then a series of interchanges between ragams (unmetered melody) and Tanam (the ornamentation within a melorhythmic cycle, equivalent to the "jor"). This is intermixed with hymns called krithis. The pallavi  or theme from the raga then follows. Carnatic pieces also have notated lyrical poems that are reproduced as such, possibly with embellishments and treatments according to the performer's ideology, referred to as Manodharmam. Primary themes include worship, descriptions of temples, philosophy, and nayaka-nayika (Sanskrit "hero-heroine") themes. Tyagaraja (1759–1847), Muthuswami Dikshitar (1776–1827) and Syama Sastri (1762–1827) have been the important historic scholars of Carnatic music. According to Eleanor Zelliot, Tyagaraja is known in the Carnatic tradition as one of its greatest composers, and he reverentially acknowledged the influence of Purandara Dasa. A common belief in South India is  that Carnatic music represents a more ancient approach to classical music, whereas Hindustani music has evolved by external influences. Hindustani music. It is unclear when the process of differentiation of Hindustani music started. The process may have started in the 14th century courts of the Delhi Sultans. However, according to Jairazbhoy, the North Indian tradition likely acquired its modern form after the 14th or after the 15th century. The development of Hindustani music reached a peak during the reign of Akbar. During this 16th century period, Tansen studied music and introduced musical innovations, for about the first sixty years of  his life with patronage of the Hindu king Ram Chand of Gwalior, and thereafter performed at the Muslim court of Akbar. Many musicians consider Tansen as the founder of Hindustani music. Tansen's style and innovations inspired many, and many modern "gharanas" (Hindustani music teaching houses) link themselves to his lineage. The Muslim courts discouraged Sanskrit, and encouraged technical music. Such constraints led Hindustani music to evolve in a different way than Carnatic music. Hindustani music style is mainly found in North India, Pakistan and Bangladesh. It exists in four major forms: Dhrupad, Khyal (or Khayal), Tarana, and the semi -classical Thumri. Dhrupad is ancient, Khyal evolved from it, Thumri evolved from Khyal. There are three major schools of Thumri: Lucknow gharana, Banaras gharana and Punjabi gharana. These weave in folk music innovations. Tappa is the most folksy, one which likely existed in Rajasthan and Punjab region before it was systematized and integrated into classical music structure. It became popular, with the Bengali musicians developing their own Tappa. Khyal is the modern form of Hindustani music, and the term literally means "imagination". It is significant because it was the template for Sufi musicians among the Islamic community of India, and  Qawwals sang their folk songs in the Khyal format. Dhrupad (or Dhruvapad), the ancient form described in the Hindu text "Natyashastra", is one of the core forms of classical music found all over the Indian subcontinent. The word comes from "Dhruva" which means immovable and permanent. A Dhrupad has at least four stanzas, called Sthayi (or Asthayi), Antara, Sanchari and Abhoga. The Sthayi part is a melody that uses the middle octave's first tetrachord and the lower octave notes. The Antara part uses the middle octave's second tetrachord and the higher octave notes. The Sanchari part is the  development phase, which builds using parts of Sthayi and Antara already played, and it uses melodic material built with all the three octave notes. The Abhoga is the concluding section, that brings the listener back to the familiar starting point of Sthayi, albeit with rhythmic variations, with diminished notes like a gentle goodbye, that are ideally mathematical fractions such as "dagun" (half), "tigun" (third) or "chaugun" (fourth). Sometimes a fifth stanza called Bhoga is included. Though usually related to philosophical or Bhakti (emotional devotion to a god or goddess) themes, some Dhrupads were composed to praise kings. Improvisation is of  central importance to Hindustani music, and each "gharana" (school tradition) has developed its own techniques. At its core, it starts with a standard composition (bandish), then expands it in a process called "vistar". The improvisation methods have ancient roots, and one of the more common techniques is called "Alap", which is followed by the "Jor" and "Jhala". The "Alap" explores possible tonal combinations among other things, "Jor" explores speed or tempo (faster), while "Jhala" explores complex combinations like a fishnet of strokes while keeping the beat patterns. As with Carnatic music, Hindustani music has assimilated various folk tunes. For example , ragas such as Kafi and Jaijaiwanti are based on folk tunes. Persian and Arab influences. Hindustani music has had Arab and Persian music influences, including the creation of new ragas and the development of instruments such as the sitar and sarod. The nature of these influences are unclear. Scholars have attempted to study Arabic "maqam" (also spelled "makam") of Arabian peninsula, Turkey and northern Africa, and "dastgah" of Iran, to discern the nature and extent. Through the colonial era and until the 1960s, the attempt was to theoretically study "ragas" and "maqams" and suggested commonalities. Later comparative musicology studies, states  Bruno Nettl – a professor of Music, have found the similarities between classical Indian music and European music as well, raising the question about the point of similarities and of departures between the different world music systems. One of the earliest known discussions of Persian "maqam" and Indian "ragas" is by the late 16th century scholar Pundarika Vittala. He states that Persian "maqams" in use in his times had been derived from older Indian "ragas" (or "mela"), and he specifically maps over a dozen "maqam". For example, Vittala states that the "Hijaz maqam" was derived from the "Asaveri raga", and "Jangula  was derived from the Bangal". In 1941, Haidar Rizvi questioned this and stated that influence was in the other direction, Middle Eastern "maqams" were turned into Indian "ragas", such as "Zangulah maqam" becoming "Jangla raga". According to John Baily – a professor of Ethnomusicology, there is evidence that the traffic of musical ideas were both ways, because Persian records confirm that Indian musicians were a part of the Qajar court in Tehran, an interaction that continued through the 20th century with import of Indian musical instruments in cities such as Herat near Afghanistan-Iran border. Features. Classical Indian music is a  genre of South Asian music, the other being film, various varieties of pop, regional folk, religious and devotional music. In Indian classical music, the "raga" and the "tala" are two foundational elements. The "raga" forms the fabric of a melodic structure, and the "tala" keeps the time cycle. Both "raga" and "tala" are open frameworks for creativity and allow a very large number of possibilities, however, the tradition considers a few hundred "ragas" and "talas" as basic. "Raga" is intimately related to "tala" or guidance about "division of time", with each unit called a "matra" (beat, and duration between beats ). Raga. A "raga" is a central concept of Indian music, predominant in its expression. According to Walter Kaufmann, though a remarkable and prominent feature of Indian music, a definition of "raga" cannot be offered in one or two sentences. "Raga" may be roughly described as a musical entity that includes note intonation, relative duration and order, in a manner similar to how words flexibly form phrases to create an atmosphere of expression. In some cases, certain rules are considered obligatory, in others optional. The "raga" allows flexibility, where the artist may rely on simple expression, or may add ornamentations  yet express the same essential message but evoke a different intensity of mood. A "raga" has a given set of notes, on a scale, ordered in melodies with musical motifs. A musician playing a "raga", states Bruno Nettl, may traditionally use just these notes, but is free to emphasize or improvise certain degrees of the scale. The Indian tradition suggests a certain sequencing of how the musician moves from note to note for each "raga", in order for the performance to create a "rasa" (mood, atmosphere, essence, inner feeling) that is unique to each "raga". A "raga" can be written  on a scale. Theoretically, thousands of "raga" are possible given 5 or more notes, but in practical use, the classical Indian tradition has refined and typically relies on several hundred. For most artists, their basic perfected repertoire has some forty to fifty "ragas". "Raga" in Indian classical music is intimately related to "tala" or guidance about "division of time", with each unit called a "matra" (beat, and duration between beats). A "raga" is not a tune, because the same "raga" can yield a very large number of tunes. A "raga" is not a scale, because many "ragas" can be based  on the same scale. A "raga", states Bruno Nettl and other music scholars, is a concept similar to mode, something between the domains of tune and scale, and it is best conceptualized as a "unique array of melodic features, mapped to and organized for a unique aesthetic sentiment in the listener". The goal of a "raga" and its artist is to create "rasa" (essence, feeling, atmosphere) with music, as classical Indian dance does with performance arts. In the Indian tradition, classical dances are performed with music set to various "ragas". Tala. According to David Nelson – an Ethnomusicology scholar specializing in  Carnatic music, a "tala" in Indian music covers "the whole subject of musical meter". Indian music is composed and performed in a metrical framework, a structure of beats that is a "tala". A "tala" measures musical time in Indian music. However, it does not imply a regular repeating accent pattern, instead its hierarchical arrangement depends on how the musical piece is supposed to be performed. The "tala" forms the metrical structure that repeats, in a cyclical harmony, from the start to end of any particular song or dance segment, making it conceptually analogous to meters in Western music. However, "talas  have certain qualitative features that classical European musical meters do not. For example, some talas" are much longer than any classical Western meter, such as a framework based on 29 beats whose cycle takes about 45 seconds to complete when performed. Another sophistication in "talas" is the lack of "strong, weak" beat composition typical of the traditional European meter. In classical Indian traditions, the "tala" is not restricted to permutations of strong and weak beats, but its flexibility permits the accent of a beat to be decided by the shape of musical phrase. The most widely used "tala" in the  South Indian system is "adi tala". In the North Indian system, the most common "tala" is "teental". In the two major systems of classical Indian music, the first count of any "tala" is called "sam". Instruments. Instruments typically used in Hindustani music include the sitar, sarod, surbahar, esraj, veena, tanpura, bansuri, shehnai, sarangi, violin, santoor, pakhavaj and tabla. Instruments typically used in Carnatic music include veena, venu, gottuvadyam, harmonium, mridangam, kanjira, ghatam, nadaswaram and violin. Players of the tabla, a type of drum, usually keep the rhythm, an indicator of time in Hindustani music. Another common instrument is the stringed  tanpura, which is played at a steady tone (a drone) throughout the performance of the raga, and which provides both a point of reference for the musician and a background against which the music stands out. The tuning of the tanpura depends on the raga being performed. The task of playing the tanpura traditionally falls to a student of the soloist. Other instruments for accompaniment include the sarangi and the harmonium. Notation system. Indian classical music is both elaborate and expressive. Like Western classical music, it divides the octave into 12 semitones of which the 7 basic notes are, in  ascending tonal order, "Sa Re Ga Ma Pa Dha Ni " for Hindustani music and "Sa Ri Ga Ma Pa Dha Ni " for Carnatic music, similar to Western music's "Do Re Mi Fa So La Si ". However, Indian music uses just-intonation tuning, unlike some modern Western classical music, which uses the equal-temperament tuning system. Also, unlike modern Western classical music, Indian classical music places great emphasis on improvisation. The underlying scale may have four, five, six or seven tones, called "swaras" (sometimes spelled as "svaras"). The "swara" concept is found in the ancient "Natya Shastra" in Chapter 28 . It calls the unit of tonal measurement or audible unit as "Śhruti", with verse 28.21 introducing the musical scale as follows, These seven degrees are shared by both major "raga systems", that is the North Indian (Hindustani) and South Indian (Carnatic) systems. The solfege ("sargam") is learnt in abbreviated form: "sa, ri (Carnatic) or re (Hindustani), ga, ma, pa, dha, ni, sa". Of these, the first that is ""sa"", and the fifth that is ""pa"", are considered anchors that are unalterable, while the remaining have flavors that differs between the two major systems. Contemporary Indian music schools follow notations and  classifications (see melakarta and thaat). These are generally based on a flawed but still useful notation system created by Vishnu Narayan Bhatkhande. Reception outside India. According to Yukteshwar Kumar, elements of Indian music arrived in China in the 3rd century, such as in the works of Chinese lyricist Li Yannian. In 1958, Ravi Shankar came to the US and started making albums. These started a 1960s penchant for Indian classical music in the States. By 1967 Shankar and other artists were performing at rock music festivals alongside Western rock, blues, and soul acts. This lasted until the mid-1970s. Ravi Shankar  performed at Woodstock for an audience of over 500,000 in 1969. In the 1980s, 1990s and particularly the 2000s onwards, Indian Classical Music has seen rapid growth in reception and development around the globe, particularly in North America, where immigrant communities have preserved and passed on classical music traditions to subsequent generations through the establishment of local festivals and music schools. Numerous musicians of American origin, including Ramakrishnan Murthy, Sandeep Narayan, Abby V, and Mahesh Kale have taken professionally to Indian Classical Music with great success. In his 2020 released video, Canadian singer Abby V demonstrated 73 different Indian Classical  ragas in a live rendering, which went viral on the internet; further establishing the growing prominence of Indian Classical Music around the globe. Organizations. SPIC MACAY, established in 1977, has more than 500 chapters in India and abroad. SPIC MACAY claims to hold around 5000 events every year related to Indian classical music and dance. Prayag Sangeet Samiti is also a well established organizastion promoting Indian Classical Music.
