Answer to Question 1
celebration of heroic passion, a vivid confrontation between two war gods
Answer to Question 2
Agbekor Song 1 : A1 A2 : B B A2 = A B A, ternary.
Agbekor Song 2 : A1 B1 A2 B2 : = A B, binary
Agbekor Song 3 : A1 A2 :: B1 B2 : A2 = A B A, ternary.
(In Agbekor Song 3, since at the end only A2 returns and A1 does not return, you may also think of the overall form as rounded binary, that is, basically a two-part binary form with limited reference to the opening material at the end.)
