In this part, we go a bit deeper into the
melody and rhythm concepts.
We'll see what makes a melody major or minor, and how rhythms are
classified, etc. We'll also provide pointers to resources for more
information.

Sa' (Sa of next octave) |
(Conventionally, the first note of the next octave is also included
in the list of notes of a melody, just to round up the number of notes
to eight. The eighth note is usually written as Sa'.)
Some Carnaatic music literature use an alternate convention, referring to certain notes
with multiple names (similar to referring to the same note as C# or D
flat). We won't use the alternate convention in this article, but will
later briefly see why it exists.
Unlike in western music, there is no specific frequency attached to an octave note. An octave note merely indicates the position of the note within an octave.
Major MelodiesA major melody is one that uses exactly seven octave notes in each
octave. In the context of the melody, these seven notes are referred to
as melody notes (svaram),
and are referred to using the names Sa, Ri, Ga, Ma, Pa, Dha, Ni. Thus,
a melody note acts as an alias for an octave note in the context
of the
melody (the melody provides a 'name space' for the notes of the
melody). The combination of a melody name and a melody note uniquely
identifies an octave note. (Think of the melody notes Sa, Ri, Ga,
etc. as a Carnaatic version of Do, Re, Mi, etc.)
Henceforth, when we use the term 'note' in this article without any qualification ('octave' or 'melody'), it is assumed to mean 'melody note'.
The example below shows how the same note (say Ga)
in two melodies could map to different octave notes.

In addition to using exactly seven notes, there are some other rules
that make a melody major: a) the same seven notes must be used during
both the ascending sequence (moving from a low note to a high note) and
the descending sequence (high to low), b) the melody notes must be mapped
to the octave notes according to the scheme shown below:
| Melody note(s) |
Available octave note(s) |
Octave note mapping choice(s) |
Number of possible choice(s) |
| Sa | Sa |
Sa |

| Ri,Ga | Ri1,Ri2,Ga1,Ga2 |
(Ri1,Ri2), (Ri1,Ga1), (Ri1,Ga2), (Ri2,Ga1), (Ri2,Ga2), (Ga1,Ga2) |

(Dha1,Dha2), (Dha1,Ni1), (Dha1,Ni2), (Dha2,Ni1), (Dha2,Ni2), (Ni1,Ni2) |

Thus, twelve octave notes, using the above rules, give rise to to 72 major melodies (1
x 6 x 2 x 1 x 6 x 1). The first such combination of octave notes (i.e., the first melody) is numbered 1, and so on.
Here are the octave notes of the first two major melodies:

Every minor melody is derived from a major melody. Minor melodies
are defined as follows: a) in any octave, the melody must have at
least
five unique notes (of its parent melody), b) the notes Sa and Pa must
be among the five, c) the melody may use different notes during ascension and
descension, d) backtracking is allowed -
i.e., the ascending sequence could descend momentarily, and/or the
descending sequence could ascend momentarily, e) the
melody could include all the seven notes of a major melody, plus one or
two notes from another major melody (in this case its parent is
arbitrarily chosen to be one of the two major melodies). There are a
few
additional rules/relaxations, but these are the main ones.
These rather lax rules result in thousands of minor melodies.
However, only a few hundreds of them are actually in vogue. here are a few examples of minor
melodies:
| Melody name |
Parent melody name (number) |
Notes |
What makes it a minor melody |
| Bilahari |
Shankaraabharanam (29) |
Sa Ri Ga Pa Da Sa' Sa' Ni Da Pa Ma Ga Ri Sa |
Ascending sequence contains only 5 notes. |
| Sahaana |
Harikaambhoji (28) |
Sa Ri Ga Ma Pa Ma Dha Dha Ni Sa' Sa' Ni Da Pa Ma Ga Ma Ri Ga Ri Sa |
Ascending sequence backtracks a little bit (Ma Pa Ma), also Dha is always of double duration (Dha Dha) Descending sequence backtracks (Ma Ga Ma Ri Ga Ri) |

The first line starts in sync with the beat, but the second line starts with the word 'And', a little earlier
than when the rhythm cycle starts (with the word 'everywhere').
Late Start (anaagatha): Similarly, a line of a song might be longer than a cycle of beats
causing the next line to start later than the start of the rhythm cycle.
If a song's description states neither an early start nor a late
start, it can be assumed to start concurrently (sama) with the start of the
rhythm cycle.
Multiple Beats (kalai): Sometimes a single
line of song is long enough to occupy multiple cycles of a rhythm. In such
cases, each beat in the rhythm cycle is repeated to make a single cycle last for the duration of
the line. For
example: if the line
of song is sixteen beats long and the composer has chosen an
eight-beat rhythm cycle (12341212), the rhythm cycle will be
played as 1122334411221122. The most common multiple is 2 (each beat played twice as we just saw - this is referred to as 2-kalai), but could be more.
Gait or sub-rhythm (nadai or gathi)
- While the meter of the song dictates the rhythm cycle, the lengh of a
phrase dictates the length of each beat (i.e., the interval
between successive beats).
For example: the rhythm cycle could be 4 beats long (1234), but the
interval
between two successive beats may be long enough to be counted as three
sub-beats, as
in:
| Four beat rhythm cycle |

The four beat, three sub-beats rhythm cycle is pretty common in
other music systems too. For example, the following song in the film
"Sound of Music" is set to a four beat, three sub-beat rhythm cycle:
| Rain drops, and |
roses, and |
whiskers on |
kittens |
