Actually, all swarasthanas deviate from their respective western notes!
Take a look at this visualization that shows the deviation of carnatic swarasthanams from their nearest western equal-tempered notes:
As you can clearly see from the chart:
- Eight swarasthanas sound lower than keyboard notes.
- Three swarasthanas sound higher.
- Range of deviation is -15.64 cents (Dha2) to +11.73 cents (Ri1)
Many carnatic music teachers make their students practice swarasthanas on keyboard in the hope that it might help them to improve their swara gyanam. Contrarily, it will only destroy their sense of swarasthana as most of the notes on a keyboard are very wrong. Let us fully understand the danger: according to this study, use of harmonium, which is also an equal tempered keyboard, has permanently skewed Hindustani music’s swara ratios. Fortunately, influence of harmonium is minimal in carnatic music, and the study says, we still retain the purity of our swarasthanas.
What is the alternative?
Absence of appropriate technology for carnatic is the reason why our teachers and students have to resort to other means such as keyboards.
On our part, we have created Shruti Carnatic Tuner, a reliable companion for authentic carnatic swarasthanas. It provides accurate reference tones. It also detects and shows you the swarasthanam when you sing or play. We, at Kuyil, will continue to innovate apps tailor-made for carnatic that will empower teachers, students and performers.
