Marwa Thaat

Two swaras move in opposite directions — Re down to komal Re, Ma up to tivra Ma — which is why a count of two describes Marwa and Kafi equally badly.

Marwa moves two swaras in opposite directions: Re falls to komal Re and Ma rises to tivra Ma. Its komal/tivra count is two, exactly like Kafi’s and Bhairav’s, and the three frames share almost nothing else — which is the clearest argument on this site against reading the count as a measure of similarity.

The seven swaras, from Sa

Declared as semitone offsets from Sa, then read through the same fixed chromatic-to-sargam table every thaat on this site uses — the frame’s seven available positions, not a raga’s actual phrasing. Against the Bilawal reference this frame moves two swaras.

Where it falls on the sitar

With Sa placed on C, every fret across all five strings whose pitch class is one of Marwa’s seven swaras — computed from the registry’s true open pitches and the instrument’s fifteen-fret board:

5th string (C3)0, 1, 4, 6, 7, 9, 11, 12, 13Sa, Komal Re, Ga, Tivra Ma, Pa, Dha, Ni, Sa, Komal Re

Because one swara falls and one rises, the position total stays at Bilawal’s forty-five: what the komal Re pulls into the span at the bottom, the tivra Ma pushes out at the top. On the C strings frets 1, 6 and 13 light while 2, 5 and 14 go dark; on the G strings only two positions move at all, 6 and 11 lighting where 7 and 10 were. No other frame here rearranges so much for so little change in count.

A frame, not a raga

This set of seven pitch classes matches nothing in this site’s 12-TET scale library — the comparison simply does not resolve, and saying so is more useful than forcing a Western name onto it. Marwa, Puriya and Sohini are conventionally grouped under this thaat and are distinguished in performance by which swaras they emphasise and how they treat Pa, several of them omitting it entirely. That is raga practice, not the frame.

Where to start

Approach it from Kalyan, which has the tivra Ma and leaves Re alone: adding komal Re on top of it is the whole distance between the two frames. Then look at Purvi, which is this frame with komal Dha added. Both comparisons are one swara wide, and playing them in that order through the fretboard explorer is the fastest way to hear a family rather than three unrelated tables.
