Graha Bedham & Sruti Bedham

[mukundan.r...@centigram.com]

First can someone explain me clearly about these things in Carnatic
music
?.

I have gone thru different primers that exist out there in diff
websites but I have some doubts that need to be explained.

My understanding is
1. A raga has a set of swaras whose relative positions w.r.t Sa is
fixed, and whose absolute pitches are determined by absolute pitch of Sa,

2. When a ragamalika is being sung, in order to distinguish between
the ragas, the performer(say singer) will have his Sa fixed at some
absolute pitch and will sing the swarasthanas for that particular
raga based on this Sa.

Now, my confusion is whether this (Graha Bedham, Sruti Bedham) is same as
singing another raga with Sa changed.

Thanks.

The basic difference between Ragamalika and Grahabhedam is, in ragamalika
it is not necessary to change the shruti to show another raga, whereas in
Grahabhedam the Adhara shruti itself is changed but the notes are not
changed again. Let me explain this in more detailed manner with examples.

In a ragamalika, any raga can be chosen to follow or preceded by any other
raga, but the basic shruti, i.e., Sa never changes the pitch.

Whereas in Grahabhedam, for example, if grahabhedam is being done in say,
raga Nagaswaravali, which has notes Sa Ga Ma Pa Da, If Ma is taken as Sa,
and subsequently, Ma, Pa, Da, Sa, Ga in sequence, it sounds like Sa, Ri,
Ga, Pa, Ni of Hamsadhwani. So, Super imposing Nagaswaravali on itself by
making its Ma as Sa, it becomes Hamsdhwani, in other words, the Shruti is
also being shifted here, so one can call it ShrutiBhedam also, though I did
not here of such a word. What all I heard about is GrahaBhedam and this is
it.

In some ragas, there is more scope to show these things more clearly. For
instance, ragas Shankarabharanam, Thodi, Kalyani and even Kharaharapriya
all can be shown in NataBhairavi by doing GrahaBhedam in different places
like Ri, Ga, Ma, Pa etc.

The point here, is when GrahaBhedam is being done, the raga's scale is not
changed but it gives the effect of another raga because of change in
shruti, whereas in a ragamalika, the raga itself is chosen without changing
the Shruti

Hi Nagraj,

Thank you for the explanation you have given here. It does explain to me
very clearly what this concept is. My doubt still is if the scale is not
changed, then how would one distinguish between the ragas ? Because,
can't I always think of it as Nagaswaravali being sung from Ma onwards,
instead of Hamsadhwani ??.

Thanks.
Bye,
Mukund.
