The chapu talas have their avartanam structures, namely 3, 5, 7, 9 beats per cycle, but do not specify the angas (namely, body or constituent parts).
Can we still use the regular angas (as described in the tala dasapranas and the 108 talas, suladi talas, etc) in describing the structure of the chapu talam? For example, a Tisra Chapu is Tha Ki Ta, and from the hand movements, can be split into 1 + 2. This can be viewed as an Anudhrutham followed by a Dhrutham.
Similarly, Khanda Chapu is Tha ka Tha ki ta (2 + 3), but can be construed as 2 + 1 + 2 based on the hand movements. Can this then be viewed as a Dhrutham followed by an Anudhrutham followed by a Dhrutham?
Misra and Sankeerna Chapus can be similarly represented. It bothers me a little that we have the Tala dasapranas, and angas, that are used by both the 108 talas as well as the Suladi talas, but the Chapu talas don't have any defined angas, merely 2+3 etc. Are there defined angas for the Chapu talas? Is it ok to use the Anudhrutham/dhrutham to describe them, or is it blasphemous?
