mūrcchanā-s are deprived of sa, ri and ga respectively, they form into
twentyone note-series. Taken together, we get forty-nine hexatonic
note-series. That is how the standard mūrcchanā-s being deprived of
one or two notes become combinational note-series.

(3) The pentatonic note-series : (29c-31b)
Besides, the seven (standard mūrcchanā-s) of the ṣaḍja-
-grāma being deprived of sa and pa, ga and ni¹ and ri and pa
respectively form twentyone pentatonic note-series; while
those of the madhyama-grāma being short of ri and dha and ga
and ni² respectively become fourteen (tāna-s): altogether,
they make thirtyfive. (29c-31b)
Just as the standard mūrcchanā-s by dropping one note become
hexatonic note-series, by dropping two notes they become pentatonic
note-series. In ṣaḍja-grāma, by the omission of sa and pa we get one set
of seven pentatonic note-series, by the omission of ga and ni, another set
of seven and by the omission of ri and pa the third set of seven, making
twentyone in all. Similarly, in the madhyama-grāma by the omission of
1 & 2. Dviśruti of the text literally means a bi-śrutic note; ga
and ni are the two notes with two śruti-s each.

   (1) Total number of hexatonic and pentatonic combinational
   note series (śuddha-tāna-s) : (31cd)
   However, the hexatonic and the pentatonic (specific
   combinational) note-series make eightyfour in all. (31cd)
   (ii) The formation and the number of kūṭa (permutational)
   tāna-s (note-series) : 32-49
   (1) The definition of kūṭa-tāna (permutational) note-
   series) : (32 abc)
   The complete or incomplete mūrcchanā-s with their notes
   produced in a permuted form become permutational note-
   series (kūṭa-tāna-s). (32a-32c)
   ri and dha we get one set of seven pentatonic series, and by the omission
   of ga and ni, the second set, making fourteen in all. Thus the pentatonic
   note-series in both the grāma-s are counted as thirtyfive and the number
   of both the hexatonic and the pentatonic note-series in both the grāma-s
   is considered to be (49+35 = 84) eightyfour. An illustration of a penta-
   tonic note-series is given as under. We know that mūrcchanā is in the
   ascending as well as in the descending order of notes.
