Hindustani music emphasizes improvisation and exploration of all aspects of a raga, while Carnatic performances tend to be short composition-based.
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.
[10] 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.
The earliest Indian thought combined three arts, syllabic recital (vadya), melos (gita) and dance (nrtta).
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,[18][19] it is sections of Rigveda set to music.
[27] Time keeping with idiophones was considered a separate function than that of percussion (membranophones), in the early Indian thought on music theory.
[27] 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.
[28] 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.
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 Kannada, Odia, Pali (Buddhism), Prakrit (Jainism), Tamil and Telugu.
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.
He travelled widely sharing and teaching his ideas, and influenced numerous South Indian and Maharashtra Bhakti movement 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).
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.
[54] Tansen's style and innovations inspired many, and many modern gharanas (Hindustani music teaching houses) link themselves to his lineage.
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.
[58] 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).
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.
[74] 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.
[11] 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.
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.
[77] 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.
[80] 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.
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.
[82] Instruments typically used in Hindustani music include the sitar, sarod, surbahar, esraj, veena, tanpura, bansuri, shehnai, sarangi, violin, santoor, pakhavaj and tabla.
[84] Instruments typically used in Carnatic music include veena, venu, gottuvadyam, harmonium, mridangam, kanjira, ghatam, nadaswaram and violin.
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.
[citation needed] 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.
[92] Numerous musicians of American origin, including Ramakrishnan Murthy, Sandeep Narayan, Pandit Vikash Maharaj, Abby V, and Mahesh Kale have taken professionally to Indian Classical Music with great success.
[95] Akhil Bharatiya Gandharva Mahavidyalaya Mandal (अखिल भारतीय गान्धर्व महाविद्यालय मंडल) is an institution for the promotion and propagation of Indian classical music and dance.
