I N SOUTH INDIAN MELAS
Jay Rahn
I n a prev ious a r t i c l e , I have o u t l i n e d f e a t u r e s common t o
s c a l e s around t h e w o r l d . These inc lude penta tonic , hep ta ton ic , and
equihepta tonic s c a l e s found i n t h e music of many c u l t u r e s a s w e l l as
l o g and s l end ro forms of Indones ia , t h e - i n s c a l e of Japan, Arabian
maqamat, and t h e t o n a l m a t e r i a l of North Indian rags. A no tab le omission
from t h a t account was t h e system of mT1a.s found i n South Ind ia . A s i t
t u r n s o u t , c e r t a i n Ca rna t i c mG1as appear a t f i r s t t o be excep t iona l i f

However, on c l o s e r i n spec t ion , one f i n d s t h a t t h e s e "exceptional" s c a l e s
might b e s t be considered no t s c a l e s i n t h e sense of t h e previous paper

t h e i r s p e c i a l s t a t u s i s mir rored i n t h e number of s p e c i a l forms ( o r

of t h e i r r e l a t i v e p o p u l a r i t y among musicians and t h e degree t o which
they a r e considered t o be " natura l" a s opposed t o " a r t i f i c i a l " .
DATA BASE
The d a t a used a s a b a s i s f o r t h i s s tudy c o n s i s t of t h e almost 2,000
j anya rzgas compiled i n Walter Kaufmannfs book on The ~ z ~ a s of South Ind ia . 2
The r&as o u t l i n e d i n Kaufmannls p u b l i c a t i o n a r e based on an oc tave of
110
twelve notes, five to seven of which are used in each rzga. Only the
pitch contents of individual rggas are dealt with here. Special phrases,
none of which have been subjected to classification, are not included,
nor is the distinction between ascending and descending forms and various
vakra (or "zig-zag") features. In short, I am concerned with what -
pitches are used in given ragas, not with how they are used.
The rzgas described in Kaufmannls treatise are grouped in
Carnatic theory into 72 mGlas, or familes of rzgas, depending on their
- - pitch content (Figure 1). These 72 melas constitute the Kanakangi-
- - system, dating at the latest from the closing years of the
eighteenth century or the beginning of the nineteenth. According to
Kaufmann, each of the 72 mTlas is a "rigid, 'impersonal' seven-tone
scale Each rLga belonging to a given mgla family represents a
subset of from five to seven tones of these seven. The question to be
dealt with here is as follows: In what sense are the 72 melas to be
considered scales?
As I mentioned above, I have described a number of features
common to scales throughout the world in an earlier study. Relevant to
the present discussion is a feature which I have termed "cyclic bisection."
In a seven-tone scale that has the feature of cyclic bisection, any
scale degree is from one-half to two-thirds an octave away from the
scale degrees that are four steps.away. This feature is shared by all
the well-documented seven-tone scales outside South India: the equi-
heptatonic, @hog, and diatonic systems, as well as the scales on which
Arabian magamat and North Indian rags are based. Cyclic bisection can
be considered, then, to define seven-tone scales around the world.
I 11 -
However, if one examines South Indian melas, one finds that some feature
cyclic bisection and others do not. This raises an important question.
Are South Indian melas scales or not? If they are scales, cyclic bi-
section cannot be a definitive feature of scales and the previous defi-
nition of scales must be withdrawn. And if they are not scales, what
are they?
In order to answer these questions, one can backtrack a bit
and compare two melas one of which features cyclic bisection and one of
which does not. First, consider mela ~anakan~i, the first mela in
Figure 1. Its tones can be arranged in a cycle such that each tone is
one-half to two-thirds an octave from its neighbours. To state this
another way, one can say that each tone is 6 to 8 semitones from ad-
jacent members of the cycle (Figure 2). - - -
For comparison, one can consider mela Ganamurti, the third
mela in Figure 1. This mela does not feature cyclic bisection. As one - can observe in Figure 3, the interval between - ebb and - b in the cycle for - - Ganamurti is 9 semitones, in other words, three-quarters of an octave,
- - which is larger than two-thirds. It would seem that melas like Kanakangi
resemble scales throughout the world, and ones like ~gnamirti are
exceptional. How can this be?

A clue is offered by Kaufmann when he writes that "the quantity
(i.e., the number or frequency) of janyas is a comparatively good
indicator of the importance and popularity of the primary mgla. Some
of the frequently performed mela-ragas have large numbers of j anyas,
such as melas 8, 15, 20, 22, 28, and 29. These basic scales and their
subordinate forms are particularly favored by South Indian performers
112
and t h e i r audiences. Other s c a l e s , p a r t i c u l a r l y those of melas wi th a
smal l number of j anyas enjoy l i t t l e p o p u l a r i t y and a r e o f t e n descr ibed
as being too " a r t i f i c i a l . " I f one checks t h i s s ta tement i n l i g h t of

are i n t h e minor i ty . Of t h e 72 mzlas, 45 f e a t u r e c y c l i c b i s e c t i o n '
whereas 27 do not.5 Thi rd ly , t hose melas t h a t f e a t u r e c y c l i c b i s e c t i o n

f e a t u r e c y c l i c b i s e c t i o n has 18 janyas . Furthermore, mGlas t h a t f e a t u r e
c y c l i c b i s e c t i o n have a range of from 12 t o 132 janyas ap iece , whereas
melas t h a t do n o t f e a t u r e c y c l i c b i s e c t i o n have from 1 3 t o 28 (F igure

I f one cons iders Kaufmann's remark t h a t "mkas wi th a smal l
number of j anyas ... a r e o f t e n descr ibed a s being too a r t i f i c i a l " ,
o t h e r avenues of explana t ion emerge. F i r s t , t h e world-wide tendency
toward " c y c l i c b i sec t ion" i n seven- tone s c a l e s can be considered t o
r ep re sen t a psychologica l o r pe rcep tua l u n i v e r s a l , as I have suggested
e l ~ e w h e r e . ~ Another way of s t a t i n g t h i s is t o s ay t h a t c y c l i c b i s e c t i o n
is a "natural" way of making music. Accordingly, pieces which do not
feature cyclic bisection could be considered "artificial" in comparison
with those that do. In this sense, Kaufmann's correlation of poularity
with natural-ness appears vindicated by the figures presented above.
Within the realm of the "artificial," there is a broad spectrum
of possibilities. Which possibilities are found in South Indian &as?
This seems to be a broad, indeterminate question, for it involves
defining the range of variation within "exceptional" cases. This is not
a usual procedure in musical research, which typically isolates "regular"
features and leaves undefined the residue of "irregular" instances. In
the present situation, however, the apparently irregular cases are found
to bear a strict relationship to those that are regular. This point can
be illustrated with reference to Figure 3. There one can observe that
b if - ebb were - eb or if - b were - b , the pitch collection would feature
cyclic bisection. Indeed, the same holds for the other 26 irregular
melas. If one or two pitches were displaced a semitone, the resulting
collections would feature cyclic bisection and would be identical with
'-. 'I regular" melas. In this way, the apparently regular melas can be
considered close variants or transformations of the regular mGlas. More-
over, the relationships between regular melas and their variants is
uniform; the variant is always just a semitone away from the regular
form.
A related regularity consists in the fact that at least one of
the pitches in an "irregular" interval is always a semitone away from
the next higher or lower pitch of the m<la in which it is found.
Turning to Figure 3 again, one can observe that pitches fl and - b form
t he i r r e g u l a r i n t e r v a l of 9 semitones. A s i t t u r n s ou t , i s a semitone
from t h e next h ighe r p i t c h i n t h e mGla, namely, c, and - ebb i s a semitone
b away from t h e next lower p i t c h , namely . Another way of s t a t i n g t h i s
is t o s ay t h a t - b forms a l ead ing tone t o - c and - ebb forms a l ead ing tone
t o - db. This can b e observed more c l e a r l y i n Figure 5 where t h e mGla
p i t c h e s are arranged from low t o high (Figure 5 ) . An important f a c t i n
t h i s r ega rd i s t h a t t h i s leading- tone ' re la t ionship i s found i n a l l t h e
i r r e g u l a r i n t e r v a l s i n a l l t h e i r r e g u l a r mGlas.
I n s h o r t , i t would appear t h a t t h e i r r e g u l a r melas can be
derived from r e g u l a r mGlas according t o a uniform t ransformat ion such
t h a t by s h i f t i n g t h e p i t c h of one o r both tones i n a r e g u l a r i n t e r v a l an

members of t h e r e g u l a r mgla. Though t h e term leading- tone might seem
somewhat e t h n o c e n t r i c , one should observe t h a t leading- tone adjustments
a r e found i n musical c u l t u r e s a s widely d i v e r s e a s those of Japan,
8 Indonesia , and t h e West. Indeed, t h e r e i s an obvious p a r a l l e l between

harmonic minor modes on t h e o t h e r i n t h i s r e spec t .
CONCLUDING REMARKS
I n conclus ion , one can no te t h a t South Indian melas can be d i -
chotomized i n t o r e g u l a r and excep t iona l forms, depending on t h e presence
o r absence, r e s p e c t i v e l y , of c y c l i c b i s e c t i o n . Regular forms r ep resen t
t h e ma jo r i t y of mzlas and a l s o tend t o have more subs id i a ry janyas . I f
t h e l a t t e r f a c t is taken a s an i n d i c a t o r of popu la r i t y , r e g u l a r melas
can a l s o be considered t o be more popular . In terms of world-wide
- t endencies , r e g u l a r melas can be considered more n a t u r a l and a r e re-
cognized a s such i n South I n d i a i t s e l f . The form which a r t i f i c i a l i t y
takes can be defined in terms of, a) the absence of cyclic bisection, b)
a single type of transformation relationship between natural and arti-
ficial forms, and c) leading-tone relationships which result from such
transformations. It would seem, then, that the regular melas are scales
in the most determinate and universal sense of the term, and the ir-
regular melas are use-scales (~ebrauchsleiter)' derived from the regular
The data base employed here could be extended in a number of
ways to develop further the ideas outlined above. Other indicators of
poularity such as frequency of actual performance could be investigated,
and more probing questions concerning the concept of artificiality could
be asked of South Indian musicians and audiences. Finally, the model
tonal systems as described here could be tested against those data which
are ultimately most important, namely, actual pieces of Carnatic music.
One can only hope, in the meantime, that the directions for further
research provided here will prove to bear fruit.
By way of conclusion, I would like to suggest a much more
general hypothesis for future research, namely, that systematically more
"elegant" or "central" forms (such as scales featuring cyclic bisection)
might tend to predominate in a given repertoire. With this hypothesis,
one might enter realms of rhythmic theory and topics even further afield.
Suffice it to say for the present that the data discussed here lend some
credence to such an hypothesis and considerable hope for the union of
theoretical and empirical studies.
