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 tāḷa, 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.
Important elements of Carnatic music
Sruti
Sruti 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. While there are an infinite number of sounds falling within a scale (or raga) in Carnatic music, the number that can be distinguished by auditory perception is twenty-two (although over the years, several of them have converged). In this sense, while sruti is determined by auditory perception, it is also an expression in the listener’s mind.
Swara
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. Unlike other music systems, every member of the solfege (called a swara) has three variants. The exceptions exist in “light” ragas, in which, for artistic effect, there may be two, one ascending (in the arohanam) and another descending (in the avarohanam).
Raga system
A 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 (ornamentation), 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.
Ragas may be divided into two classes: janaka ragas (i.e. melakarta or parent ragas) and janya ragas (descendant ragas of a particular janaka raga). Janya ragas are themselves subclassified into various categories.
Tala system
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.
Carnatic music singers usually keep the beat by moving their hands up and down in specified patterns, and using their fingers simultaneously to keep time. Tala is formed with three basic parts (called angas) which are laghu, dhrtam, and anudhrtam, though complex talas may have other parts like plutam, guru, and kaakapaadam. There are seven basic tala groups which can be formed from the laghu, dhrtam, and anudhrtam:
- Dhruva tala
- Matya tala
- Rupaka tala
- Jhampa tala
- Triputa tala
- Ata tala
- Eka tala
A laghu has five variants (called jaathis) based on the counting pattern. Five jaathis times seven tala groups gives thirty-five basic talas, although use of other angas results in a total of 108 talas.
