Two Faces Of Music
by Ganapathi Narsimhan
There is more
to music than meets the ear. There are two ways in which any piece of
music or sequence of intonated phrases can be discussed. On the one
hand, we can talk about its 'physical' characteristics such as
sound patterns which can be measured as the progression of frequencies,
mediated by amplitudes(loudness) in decibels. On the other hand, we
can talk about "meaning." These two ways are independent of each
other. We can talk about the duration, loudness and sequence of swaras
without reference to what that particular sequence means. We do not
even need to know the art and science of music. But if we want to talk
about "meaning" it is essential that we know music science, the
language of music. We might agree that chatusruti rishabam and suddha
gandharam have a common swara and frequency representation and that
the phrases: pa,da,sa and pa ni sa are different without having to debate
whether the phrases are written down or intonated loud or soft,
and in tempo, slow or fast. To borrow two terms from psycho-linguistics,
the underlying discipline in comprehension and learning, we have ‘surface
structure’ of music representing the physical characteristics and
the 'imbedded' or 'deep' structure, the meaning. In short these
represent the totality of music, both the form and content. The term
“imbedded” is appropriately chosen because meaning lies deeper than
mere sequence of sounds or of written syllables. Here there is cause
for much theoretical difficulty and therefore confusion. Meaning does
not lie in the realm of musical language, written or intonated, but
only in the underlying thought processes of the user or the listener.
Swara sequences are not swaras intonated in isolation. The way in which
swaras are intonated and are combined in sequences forming musical phrases,
determines the meaning The bridge between the surface and the deep structure
is called 'syntax' or the rules of musical grammar. It is the performer’s
latent knowledge that enables him to interpret and deliver musically
correct phrases. A listener acquires meaning from the surface structure
presented by the performer only if he/she is aware of some rules of
grammar. A critical listener comprehends scientific music by imposing
his own limited imbedded structure. While this provides him aesthetic
sensations, by virtue of his familiarity of musical grammar, he is also
able to pass judgment on the performance. A critic need not be a performer
because of the lack of essential attributes like a well trained voice
and training. An amateur and an aesthete can be both.
Meaning does
not travel from the message to the listener until the listener brings
meaning to the message. Music comprehension is also a matter of anticipation
or prediction of what the performer might deliver at a given moment
of time. Cognitive prediction means the prior elimination of unlikely
alternatives in the flow of musical phrases, in raga alapana for example.
Such
predictions are neither too narrow nor too broad. A probability measure
is brought to bear on the termination of a given phrase at a time
t to qualify the range of predictions. A well structured raga
alapana, unlike what a nadaswara vidhwan undertakes, of Anandabairavi,
for example, may be considered. This delectable raga is derived from
the melakartas, Kharaharapriya. The arohana-avarohana format of this
janya raga is:
Arohana: s g R g m P D P
S ; Avarohana: S n D P m g R
s
with an occasional
prayoga of antaragandharam, G. This raga acquires a rare and short-lived
flavor of Reetigowlai from the rendering by intellectual stalwarts like
GNB or Mahalingam when a prayoa like n D m and the occasional
phrase, g m P m are intonated subtly. A well structured raga alapana
signifies an ordered musical exercise which might commence at the adhara
swara like sa and which builds up an edifice by moving successively
to higher notes in the arohana and frequently looping backwards
in the domain of avarohana.
Take the
phrase that is delivered at time, t :
Pa, Da Pa ma Pa ma
ga Ri ga ...
The listener
endowed with sufficient raga gnana can legitimately anticipate the following
sequence as a follow up with a probability of 0.8 at time ( t + δt
):
ga ma Da pa ma ga Ri, ni
sa ga Ri ga ma...
but might not
anticipate the phrase:
ga ma pa Da pa Sa, ni Da
ma , ga ma pa ma ga Ri
ga....
Intonated
with the liberty taken to use the segment ni Da ma,
deleting pa, the phrase would be a ‘special’ prayoga,
giving a subtle flavor of Reetigowlai. This is a privilege of
the mighty and not of the ordinary mortals.
It is rarely
necessary to predict precisely the structure of an evolving series,
that a raga alapana traverses. The more knowledgeable we become
and the more familiar we become with the virtuosity of the artist, our
predictions come closer to near certainty. But the excitement resides
only in the unpredictable.>
In summing
up, we could say that we are usually able to anticipate what phrases
the artist is about to intonate because we have the abiliy to make such
predictions based on our musical knowledge and critical
listening experience. We thus sample the remaining set of alternatives
for limited matching. An accompanist on the violin, for example, keeps
these alternatives in his mind while supporting the vocalist. I have
often heard Lalgudi Jayaraman amongst others, accompanying Madurai Mani
Iyer and GNB. While accompanying Madurai Mani Iyer on a raga alapana
of Bairavi or Kambodhi, the superposition of the sounds of the vocal
chords and the violin would be on phase. But repeating the exercise
with GNB, there would be a perceptible lag in the follow up. Herein
is then the example of the predictable as against the unpredictable.
Often the violinist like Chowdiah would be carried away by his own exuberance
and would go on the lead. This is often risky because of the existence
of similarities of approach of many ragas. For example, Ariyakkudi Ramanuja
Iyengar is prone to keep the pattern hanging to confuse the violinist
like Chowdiah. In one concert Ariyakkudi was rendering a raga alapana
starting with madhyamam and progressing towards the upper shadjamam
only without extension to the rishaba-gandhara domain. The raga
flavor could have been that of Pantuvarali, Subhapantuvarali
or Varali. Chowdiah took the lead and intonated the suddha
rishabham and antara gandharam, thinking that Iyengarval was going to
elaborate Pantuvarali. Iyengar , looked at Chowdiah and said softly:
" I am going to sing : 'Karuna Yelagante' .
This is a composition of Thyagaraja in the raga Varali ! Because
music is embedded in meaning (order) and meaning is limited by the purpose
and understanding of the performer and the listener, the occurrence
of ambiguity in practice is a very rare event; and when it occurs and
is detected, it is a cause for amusement.
Syntax is concerned
with order and semantics with meaning. Musicologists do not assert that
our facility in music appreciation is not rule-governed and that the
rules are not generative in the sense illustrated in the miniature
grammar indicated below:>
Generative Grammar
(Symmetric and Asymmetric Pentatonic Scales)
Format
r m
d
s
P
S ..1
R M
D
Lexicon
{ A= s; B=(r,R), C=(m,M), D=P, E=(d,D), F=S } ..2
Segments
X 1 = A +
B + C ; Y1 = D + E + F ; X 2 = C + B + A;
Y 2 = F + E + D
..3
If S 1 and
S 2 are the arohana and the avarohana then they are
given by:
S 1 = ( X 1
+ Y 1 ) and ( X 1
+ Y 1 ) = / ( Y 1 + X
1 )
..4
S 2 = ( Y 2 + X 2 ) and
( Y 2 + X 2 ) = / ( X 2
+ Y 2 )
..5
There are three bivariants
(r,R; m,M; and d,D) which lead to a total of 2 3
= 8
arohana formats
and for each of these 8 arohana formats there are 8
avarohana formats which are the exact reverse of the 8 arohana formats.
Thus we have a total of 64 musical scales of which 8 are symmetric
and 56 are asymmetric. The music-scientist would argue that rules of
music must be rooted in meaning and related to meaning in all their
operations. Consider a miniature generative grammar of English:
Syntax
Lexicon
S = X + Y
A => A(1)= a; A(2)= the
X = A + B and B => B(1)= ball; B(2)=bicycle; B(3)= bird;
Y = C + X and thus:
B(4) = cat; B(5)= dog; B(6)= girl;
..6
S = A + B + C + A + B
B(7) = man; B(8) = teacher
C
=>C(1)= alarms; C(2) =annoys;
C(3)= avoids
C(4) = bites; C(5) = chases.
The number
of perfectly grammatical sentences that can be formed (S's)
are: 1280 given by the product: 2x 8 x5 x2 x 8; the numbers correspond
to the degrees of
freedom of
the components of S .
Let us write down some sentences that make
sense and some that do not.
Sense:
S(1) = A(2) + B(8) +
C(5) + A(1) + B(5) => The teacher chases a dog
S(2) = A(1) + B(4) +
C(1) + A(2) + B(3) => A cat alarms the bird
..7
Nonsense:
S(3) = A(2 )+ B(2) +
C(4) + A(1) + B(7) => The bicycle bites a man
S(4) = A(1) + B(6) +
C(2) + A(1) + B(1) => A girl annoys a ball
..8
So grammar
is not concerned with making sense out of a sentence. Who then is responsible
for the sensible content of an utterance? The answer is course, the
speaker. When the speaker cranks up his grammar to produce an
S he wants one that will represent a meaning he has in his
mind. He begins with an imbedded structure (thoughts) and the grammar
enables him to generate a surface structure for the meaning. The listener
reverses the flow by translating the surface structure to his own characteristic
imbedded structure. Thus the meaning that the speaker intended and the
meaning that the listener abstracted may not be identical.
The syntax
that determines the structure of a raga must be based not on how swaras
can be put together with grammatical rules at the level of surface structure(arohana-avarohana)
but how musical expressions are related at the deeper level of aesthetic
appeal. Under such conditions and constraints, most of the 64 janya
ragas would be devoid of musical appeal.
Communication
in music, a complex term, may be defined as producing a surface structure
(sequence of swara phrases) that someone can make sense of in the way
that was intended by the communicator.
