Treatment of svara
Ardha-māgadhī distinguishes itself from māgadhī in so far as it is
more concerned with the latter part of the namewise (yathākṣara)
caccatpuṭa tāla, viz. with the third laghu and the fourth pluta (extra long)
out of its four mātrā-s, viz. SSIS' (guru, guru, laghu and pluta).
What is suggested is that, in order to formulate ardha-māgadhī, the
third mātrā of the yathākṣara caccatpuṭa, which is laghu, be augmented
with half of cha-gaṇa, i. e. three mātrā-s; that is, its value should be
increased from one laghu to four (mātrās). And then having thus in-
creased its value to four mātrā-s it may be sung with the initial two
and the last two (of the eight) mātrā-s of caccatpuṭa, viz. dhruvaka and
sarpiṇī and patāka and patitā respectively. This forms the first step
as it were.
In the second step the pluta that is following the laghu is required
to be augmented by one and half the cha-gaṇa. Cha-gaṇa is a grouping
of six mātrā-s. So, to the three mātrā-s of pluta, nine more are added,
making twelve in all. Of these twelve mātrā-s, the first eight are sung
with the eight mātrā-s of caccatpuṭa in due order, and the last four by
repeating the last two mātrā-s twice in due order, i. e. with patāka,
patitā, patāka and patitā. This process forms ardha-māgadhī as based
on tāla.
Sambhāvitā and pithulā are conceived on the same lines except
that the former is set in dvikala and the latter in the catuṣkala caccatpuṭa.
This ends the Section on gīti-s and also Chapter One constituting
Volume I entitled the Svaragatādhyāya.
