Like the Quintuplets, there is no official way to count the septuplets as
far as I know. I use the same 2 methods. The first is just to count
straight from 1-7. Kind of like counting a real fast measure of 7/8 or
7/16. Except your counting subdivisions not beats.
The second is the Indian type of method. You can count this 2 ways. One
with a strong 1 and 4 feel or with a strong 1 and 5 feel.
