I
was always struck by just how difficult it can be to notate tabla or pakhavaj drumming.
When I was first learning I did what most do: wrote down the
drumming syllables in words, marking the coincidence of certain
words with beats of the tal. The problem is that one
syllable can be played in several different ways, and one stroke
may be represented by several different syllables, all dependent
on context (i.e., the context of the phrase in which it is set,
the type of piece, and even the stylistic tradition).
For
my Ph.D. dissertation (1985) I used a modified Western staff
notation with two lines for left and right hands. Above, on,
or below those lines I placed symbols for the strokes. An example
is given below:

I
found it cumbersome to produce, and many who did not read
Western notation per se found it difficult to read. For my book,
therefore, I modified this further to make the words central to
the notation, and used tabulation and spacing to infer rhythmic
information. The right hand symbols were placed above the words
and the left hand ones below. This is an example taken from The
Tabla of Lucknow (1988: ):

I
found it very easy to solve problems of fingering using these
symbols. By simply placing a black circle above a bol "ta",
for instance, I knew it was to be played on the sur (centre),
not the kinar (rim). Still, I continued to look for
ways to improve this (and probably always will).
As
part of my ongoing research into pakhavaj I came across
the Mrdang-Tabla Vadanpaddhati of Gurudev Patwardhan.
The original, written in 1903, was beautifully notated so that
not only the rhythm was clear (using the symbol system V.D. Paluskar
created for his Sangit Balbodh of 1901-03) but each
placement and fingering was also indicated by symbols. In my
efforts to transliterate his material I needed to further modify
my own symbols, and for analytical purposes I needed to ensure
there was an accurate representation of the durations Gurudev
notated. Rhythm and duration is taken care of both by the tabulation
of elements plus Western durational symbols. I have written a
book about the Mrdang-Tabla Vadanpaddhati, soon to be
published, and below is a sample of a notation from it. It is
a sath for the pakhavaj: a piece usually restricted
to one cycle without a tihai, used in accompaniment.
Twelve-count cautal is represented by a grid of 12 boxes,
read left to right, line by line. In the recording, I play it
at double the speed so that it fits twice into one cycle.

The
symbols for the notation system for pakhavaj are given
below:

The
symbols for tabla notation involve more strokes and
fingering options:

is an old tabla gat (nowadays this would generally be
called a qaida) notated by Gurudev Patwardhan in 1903
and transliterated using my system:
