Trinity of Carnatic Music
Carnatic music (Sanskrit: Karnāṭaka saṃgītaṃ) is a system of music commonly associated with the southern part of the Indian subcontinent, with its area roughly confined to four modern states of India: Andhra Pradesh, Karnataka, Kerala, and Tamil Nadu. It is one of two main sub-genres of Indian Classical Music that evolved from ancient Hindu traditions; the other sub-genre being Hindustani music, which emerged as a distinct form due to Persian and Islamic influences in North India. In contrast to Hindustani music, the main emphasis in Carnatic music is on vocal music; most compositions are written to be sung, and even when played on instruments, they are meant to be performed in gāyaki (singing) style.
Although there are stylistic differences, the basic elements of śruti (the relative musical pitch), swara (the musical sound of a single note), rāga (the mode or melodic formulæ), and tala (the rhythmic cycles) form the foundation of improvisation and composition in both Carnatic and Hindustani music. Although improvisation plays an important role, Carnatic music is mainly sung through compositions, especially the kriti(or kirtanam); a form developed between the 16th and 20th centuries by prominent composers, such as Purandara Dasa and the Trinity of Carnatic music.
Important elements of Carnatic music
Śruti commonly refers to musical pitch. It is the approximate equivalent of a tonic (or less precisely a key) in Western music; it is the note from which all the others are derived. It is also used in the sense of graded pitches in an octave.
Swara refers to a type of musical sound that is a single note, which defines a relative (higher or lower) position of a note, rather than a defined frequency. Swaras also refer to the solfege of Carnatic music, which consist of seven notes, "sa-ri-ga-ma-pa-da-ni" (compare with the Hindustani sargam: sa-re-ga-ma-pa-dha-ni or Western do-re-mi-fa-so-la-ti). These names are abbreviations of the longer names shadja, rishabha, gandhara, madhyama, panchama, dhaivata and nishada.
Raga in Carnatic music prescribes a set of rules for building a melody - very similar to the Western concept of mode. It specifies rules for movements up (aarohanam) and down (avarohanam), the scale of which notes should figure more and which notes should be used more sparingly, which notes may be sung with gamaka, which phrases should be used or avoided, and so on. In effect, it is a series of obligatory musical events which must be observed, either absolutely or with a particular frequency.
Tala refers to the beat set for a particular composition (a measure of time). Talas have cycles of a defined number of beats and rarely change within a song. They have specific components, which in combinations can give rise to the variety to exist (over 108), allowing different compositions to have different rhythms.
Nature of Carnatic music
The main emphasis in Carnatic music is on vocal music; most compositions are written to be sung, and even when played on instruments, they are meant to be performed in a singing style (known as gāyaki).Like Hindustani music, Carnatic music rests on two main elements: rāga, the modes or melodic formulæ, and the rhythmic cycles.
Today, Carnatic music is presented by musicians in concerts or recordings, either vocally or through instruments. Carnatic music itself developed around musical works or compositions of phenomenal composers .
