The two basic elements of Indian Classical
Music are Raga(Melody) and the Thala(Rhythm). Each raga consists of
a series of notes, which bear a definite relationship to the tonic note
and occur in a particular sequence. The ragas form the basis of all
melody in Indian Music. Ragas are divided into two major groups; Janaka
Ragas (Parent Melodies) and Janya Ragas (Derived Melodies). While the
number of Janaka ragas is fixed at 72, there is no limit to the number
of Janya ragas. In a concert, ragas can be sung by themselves without
any words(Raga Alapana) and then be followed by a composition in that
particular raga.
Thala or the time measure is the other principal
element in Indian Classical music. Thala is the regulating factor in
music compositions and provides a basis for rhythmic coordination between
the main artistes and the accomanists. All musical compositions other
than those sung as pure ragas (Alapana) are set to thala. There are
innumerabele varieties of thalas, out of which 7 are common. Adi thala
is the one most commonly used. In a concert, the thala is shown with
standardized combination of clap and finger counts by the musician.
There are two major systems of classical music
in India, Carnatic music and Hindustani music. Both systems have the
same origin. Due to Islamic and Persian influences, the music of northern
India evolved into a system known as Hindustani music. The Southern
part of India retained the old tradition and it is known as Carnatic
music.
Indian music is built along the lines of melody
as against the harmonic nature of western music. The solfa syllables
that correspond "do re me fa so la ti" of western music are "sa ri ga
ma pa da ni" of Indian music. The scale of equal temperament of western
music(harmony) does not suit the melodic structure of Indian music.
It is the intelligent use of these very short intervals that makes the
Indian music highly individualistic. The calliber of a musician is determined
mainly by how he/she uses these micro tones to enrich the compositions
that are sung.
The two primary instruments used as accompaniments
in a vocal concert of Carnatic music are the VIolin and MRidangam. Additionally,
there will be a drone instrument calle tambura to provide the pitch.
Additionally, there may be Ghatam, Kanjeera and Moorching, Veena, Viollin
and Flute are generally used to give solo concerts.
