Sruthi bEdham - continued:
Taking all the twelve swarams in an octave in a row, if we write the existing swarams and
leave gaps for the non existing swarams, SankarAbharaNam can be written as follows:
S - R - G M - P - D - N S'
( I tell the beginners to play Sa; oru gap Ri, oru gap Ga, Ga kittE Ma, oru gap Pa;
oru gap Dha; oru gap Ni; Ni kittE Sa' - to play SankarAbharaNam on the veena )
When we take the octave from R to R' we get this pattern:
R - G M - P - D - N S' - R'. By changing R as Shadjamam, we get this octave
S - R G - M - P - D N - S' which are KharaharapriyA swarams.
Let us take from G to G' of SankarAbharaNam. We get this octave
G M - P - D - N S' - R' - G'. By changing G as Shadjamam, we get this octave
S R - G - M - P D - N - S' which are ThOdi swarams.
The same logic to be used for shifting Sruthi to M, P, D and N. Only for 'N' we will not get a mELa rAgam,
as mentioned in the earlier post, because M1 and M2 will appear in the octave. This concept is very easy
to understand with Harmonium, Keyboard or Piano which have keys for each swaram and the Veena which
has a fret for each swaram. The violin does not have frets for each swaram and so it may be difficult to
understand. Hence I wrote the swarams with gaps, for easy understanding of the patterns. Hope it is clear!
One more interesting rAgam for fascinating sruthi bEdham is MOhanam.
The swaram pattern in ArOhaNam is: S - R - G - - P - D - - S'
Shifting sruthi to Rishabham we get S - R - - M - P - - N - S' which is MadhyamAvathi.
Shifting sruthi to Gandharam we get S - - G - M - - D - N - S' which is HindhOLam.
Shifting sruthi to Panchamam we get S - R - - M - P - D - - S' which is Suddha SAvEri.
Shifting sruthi to Daivatham we get S - - G - M - P - - N - S' which is Suddha DhanyAsi.
So, MOhanam, MadhyamAvathi, HindhOLam, Suddha SAvEri and Suddha DanyAsi are have the similar pattern of gaps
in the swarams. So any of these rAgams will bring the other rAgams by proper shift of the sruthi!
P.S: In the western music, shifting of sruthi is found. But the same notes (rAgam) will continue.
Controversy! Here is M S Amma singing the same song as the janya rAgam of HarikAmbOji!!
