Avarohin varṇa occurs where svaras descend in one order alone, either with gapless svaras or with gaps.
"Where the svaras descend in one order alone, that is called avarohin with
(120)
'equal' (gapless) svaras (or) with gaps."
<sup>87</sup>
TRANSLATION
When in the gita (melodic rendering) the svaras move (to and fro) in
mutual7 (directions) along with the last one8 (of the preceding phrase forming
the beginning of the succeeding phrase), or two by two, that is known as the
(119)
sañcārin<sup>9</sup> (circulatory) varņa.
(Anu. <sup>65</sup>)
Just as in mālavakaišika-sāsā sanipa pani nipa nisā sādharīpā pani nini; in
various (phrases) like this, on account of mutual movement (the sañcārin varņa
is formed).
(Anu. <sup>66</sup>)
Where the svaras of the gita ascend one by one or with intervening gaps,
that varņa is called ārohin (ascending). Just as in mālavapancama - pāpasa,
dharī sama ripa mapa mapadha māmā pasāri sāsama māpā rigā sā dhani pāri
mama dhani nini pāri mama dhani pādhani riripā — thus on account of
'mutual'10 (gapless) ascent or with a gap of one or two svaras the arohin
(ascending) varņa (comes into being).
Where the svaras descend in one order alone, that is called avarohin with
(120)
'equal' (gapless) svaras (or) with gaps.
pāma mamagā gaga mama mari riri ri pāmā mama papā papa pa māmama
nini dhadha papa pama gagā riri ninidhā pāpā — thus is avarohin varņa on
account of 'mutual' (gapless) descent or with a gap of one or two svaras.
Hence it has been said -
"These varnas ought to be known for the sake of the structuring" of
alankāras and the like, as being born of svaras produced by the human body 12
(and) adorned by repetition13 (in the) three registers." (NŚ XXIX. 17)
(Anu. <sup>67</sup>)
How is varna brought about? It is being answered. When the svaras stretch
the syllable<sup>14</sup> due to the demand<sup>15</sup> of melodic rendering through (their)
steadiness, circulatory movement, ascent (and) descent, then varņa (pattern of
melodic movement) is effected.
Just as, in śādjī (jātī) the sthāyin (steady) varņa (is illustrated by) sāsāsā 16.
Sancārin (circulatory varņa) is there, as in dhaivatī (jātī) — dhā 17 dhā nidha
padha mā mā mā. Ārohin (ascending varņa) (is illustrated) in nandayantī
— 18 gā gā gā pā pā dhapa mā, dhā dhā dhā dhā nī sani nidha, pā pā
pā pā pā pā pā. Avarohin (descending varņa) is (illustrated) there itself (in
nandayanti) with svaras that are equal (gapless) or are having gaps — 19pā pā
pā pā pā pā pā pā, dhā nī mā pā gā gā gā.
These varņas obtain also in the wooden20 (viņā), just as they are
