SAPTAK - THE SCALE

by David Courtney working tools


The word "saptak" has two meanings.  The first is the Eng­lish word "register".  The se­cond meaning translates to the Eng­lish word "gamut" or "the series of seven notes".  We will dis­cuss the se­cond meaning here.



The word "saptak" in Sanskrit means "containing seven" and is der­ived from the Sanskrit word "sapta" which means "seven".  (Incidentally, the Eng­lish month "September" was ori­gi­nal the seventh month in the old Roman calendar).  To understand the nature of the saptak we must return to our con­cept of the swar.  Remember that Sa and Pa are immovable.  This forms our perfect fifth.  Every other note has var­ious forms.  How­ever Hindusthani sangeet (North In­dian sys­tem) and Carnatic sangeet (south In­dian sys­tem) take dif­fer­ent views as to how many, and what these posi­tions shall be.

In Hindusthani sangeet (North In­dian sys­tem) the movable notes have two forms.  There­fore, the notes; rishabh (Re), gandhara (Ga), dhaivat (Dha), and nishad (Ni) may be either natu­ral (shuddha) or flattened (komal).  Madhyam (Ma) is unique in that its alternate form is augmented or sharp.  This note is called tivra ma.  There­fore, we find that we are ac­tually dealing with 12 swar.  This extended con­cept is shown in the table below.  These are roughly comparable to the keys on a harmonium, or piano (chromatic scale).

The si­tua­tion in Carnatic sangeet (the south In­dian sys­tem) is a bit more comp­lex.  In the South the movable notes Re (Ri), Ga, Dha, and Ni may occupy one of three posi­tions.  Ma how­ever still only occupies two posi­tions, ether natu­ral or augmented posi­tion (sharp).  This is shown in the table below.

In the previous tables we evoked a model which is somewhat si­mi­lar to the Western chromatic scale.  This is not exactly cor­rect.  We must not forget that the Western scale is based upon the equal tempered scale while the In­dian scale is based upon pure tones.  There­fore the exact level of intonations will vary.
