Dattilam is an ancient Indian musical text ascribed to the sage (muni) Dattila.
The text marks the transition from the sama-gayan (ritual chants as in the Samaveda), to what is known as gandharva music, after the gandharvas, musically adept spirits who are first mentioned in the Mahabharata.
Dattilam discusses scales (swara), the base note (sthana), and defines a tonal framework called grama in terms of 22 micro-tonal intervals (sruti) comprising one ocave.
Dattilam, dated roughly 400 AD, is the main text for this music.
This text discusses parent tonal frameworks (grama), the 22 micro-tonal intervals (srutis) placed in one octave-space, the process of sequential re-arrangement of notes (murchana), and the permutations and combinations of note-sequences (tanas).
Dattilam also describes the 18 jatis which are the fundamental melodic structures for the jati-gayan.
