GRAHABEDAM
AND SYMMETRIES
|
|
|
| The topics of this section are of
fairly advanced nature and somewhat abstract and mathematical. Readers who are not
mathematically oriented may skip this section. The basic principles behind Grahabedam and symmetry
are rooted in mathematics. Thus, a certain amount of mathematical notation is almost unavoidable in
any explanation of these concepts. Grahabedam is the process of
modifying ragas by shifting the base note Sa or the sruthi to various swara sthanas. Symmetry
indicates certain types of similarities in the structure of the swaras used in a ragam.
Grahabedam is defined
for melakartas as well as janya ragas. Consider Dheerasankaraabharanam (Bana Ma), the 29th melakarta ragam.
Theswara sthanas for it in one kattai sruthi are as shown in the following
keyboard diagram. |
