Thank you for your comment, Chitra. Kodo normally uses several notation systems from western and japanese musical traditions. But we use less notation and more dependent on the oral transmission of the rhythm called “Kuchi-shoga” which is similar to onomatopoeia. This is typical and traditional way to teach and learn rhythms often found in many local folk performing arts throughout Japan. We do not know much about Indian rhythmic theary, but when we see it as a type of oral imitation of rhythm we may be doing the similar thing. But I am sure that the Indian rhythmic theory and system should be very different from ours.
