The Carnatic music of South India has 72 scales (melakartas) comprised of seven different notes in either an ascending (arohana) or descending (avarohana) fashion. These scales are used in a kind of India music called rāga and are extremely beautiful. In addition these scales are grouped into different chakras, based on certain similarities.
Today’s melakarta is the Senavati scale (meaning “maintenance”), the first scale from the second chakra.
Below is a representation of the scale as if it was put into Western notation:
Both the first (SA) and fifth (PA) scale degrees are in a placement normal to most scales found in Western music. However, the second scale degree (RI) is lowered, creating a tendency to resolve downward. In addition, the seventh scale degree (NI) is lowered as well. While this may sound dissonant or exotic, this scale gives a great amount of opportunity to play with tension and chromatic passing tones.
Try playing around with the scale, possible harmonies, and progressions!
